I should also add, these are heavy compared to other Al cased cells, but they are actually LIGHTER, and take up less volume, than many other lifepop4 prismatic cell case variants, such as sinopoly/winston cells. But compared to other Al case cells, they are off by 50wh/kg, which is substantial. So they are not actually "heavy" for being lifepo4, but as I said in the video, they are heavy as an Al cased cell. Quick specific energy comparison from my testing: Other Al case Grade A prismatic Cells: 159-163Wh/Kg Fortune Cells: 106-110Wh/Kg Sinopoly/Winston etc: 90-110Wh/Kg So as always, it's relative. Considering the durability of these cells, it is not surprising that they weigh more than the tiny terminal Al case cells. It is WELL worth the increased weight and decreased volumetric density, in my opinion. ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Does off-grid solar confuse you?

I was starting to feel like there was not a suitable contender for the battery I'm thinking of building, but now there is, and I'm feeling happier. Has anybody used these cells ? I would be interested to see how they last in prolonged use.
Can you use these to build 6v batteries for golf carts? Or Valence batteries? Want to get away from standard batteries for my 36v Ezgo cart. I appreciate all the videos. Learning a lot.
Considering Al case Grade A prismatic cells are lighter and usually cheaper? Why would you still want to buy Sinopoly/Winston cells? For their durability? For them being more established "brands"? I will buy 300-400 Ah batteries in the near future and it's really tempting to buy the Chinese Al case cells cause of their price. On the other hand, Winston has a distributor in the EU and it feels like I would be taking less of a chance if I go for Winston.
@@Warzbag340 I think the biggest reason is that they are trusted. Personally, I would go with the newer aluminum cased cells because of improved manufacturing methods. But I'm sure the older folks will disagree with me because they used older tech cells for longer.
Very nice! The plastic shrouds are really well thought out for any shape imaginable, and make it easy to swap out tired cells. Tip for cutting threaded rod - put a nut on it first before cutting, then unscrew the nut to tidy the thread, then you can file the end burr for easy use.
@@D2O2 smart idea. I actually saw a video of the deburring tool and cringed at using a nut for all the cuts I had to do. The deburring tool took seconds and I didn't have to position the nut before every cut. Or spin it down a 2 foot rod. The deburring tool saved a lot of time and worked great. But yeah, a nut could work
@@WillProwse The tool is great if you're doing many of them a day, but otherwise it's just a thing you have to spend time looking for at the bottom of one of the toolboxes you forgot about!
I know nothing about battery systems, I came here by accident, but I love your enthusiasm, and now I find myself learning stuff about batteries. Thanks.
I used these Cells to build a 48V 300Ah battery (48 cells 3P16S) in combination with 2 MPP 5Kw inverters and a Daly BMS 16S 100/200A. It works great and I power my whole house 24/7 with it. (I live in the Philippines so no lacking of Sunlight) Actually it was Will's recommendation what made me use this cells. I ordered it in China directly from the Manufacturer for only $50 per cell.
WOW! Who cares if they are big and heavy they look great! And as a newbie I really appreciate the user friendly nature of these. It's like you almost snapped them together like Legos!😁👍❤
Will, PLEASE please please build a 400 amp hour 12 volt and 24 volt DIY systems? Preferably with these batteries hooked to both solar and a vehicle 12 volt system. Few of us can afford 4K for Battle Born, so it would be a big help. Thanks for the great content!
Will, I have been using the 100AH Fortune cells for about 2 years living fulltime in an all electric RV (no propane). I run a 200AH 48V bank with 2 Victron Quattro (split 240V). I have hit them with some pretty hefty loads and they have performed great. BTW great vids, keep 'em coming
Will! If you haven’t done a video on it, please do a quick tutorial on how to solder. I have watched other videos, but I am still not good. I’m optimistic that with your clear teaching style, I could improve with the info you would teach!
When I saw those rods I thought, “hang on a minute! No will prose review is complete without him taping something together??” Luckily he had to attach the BMS to the pack...
Hi Will. For the threaded rod.... Put your nut on the rod before you cut it , then unthread the nut past the cut and the nut will straighten the threads. Also if you cut using a dremel tool and cutoff discs , it cuts very clean but put the nut on before you cut , incase .
Mine too. I am an Electrical Engineer, but have learned more about solar from Will than any schooling. I understand power, volts amps, etc, but Will shows us the products we want and the ones we don't.
I love your videos as one who designed and installed a small remote location solar system. Eleven months ago we had to replace our batteries and wanted to go Lithium but the batteries will be in a cold environment for several months. So, we went with AGM's. At the time I was unaware of a low temp cutoff in fact I don't think there were hardly any BMS's or battery with one. That is how far things have come in just one year! If I had to do it over today I would have no problem putting in a Lithium battery system knowing I could incorporate a reliable BMS with low temp cutoff. The only problem I am having at the moment is what battery would I buy? In your series of evaluating different batteries each time you review a battery and give it a thumbs up I think that is the battery I would buy. Then you do another battery evaluation, like the one above, and my mind is changed again!!! Thanks for all the reviews you do. I have learned a ton and wish I would have had this kind of knowledge 7 years ago when I first setup the system.
John Strein make a list of top 3 batteries and roll a dice. Murphy’s Law says there will be a better cheaper battery the day your order arrives in the mail.
I understand about half of what you say in these videos, but I am understanding more the more I watch 😅 Thanks to your videos, I installed my first van system using your least favorite battery, 2 AGM 100ah Deep Cycle Batteries. But in the future I would love to build my own lithium system from cells. So keep on with these awesome videos.
For my application, I Really don't care if they are heavy or big in size, it's for my solar bank and never moved so weight is not important! Good video!
Thanks for the great evaluation. You have a wonderful channel. I'm buying 96 of these cells tomorrow to build a 144 VDC, 200AH battery bank for electric propulsion on my sailboat. This bank will also cross-charge my 24 and 12 VDC banks.
Thank you Will, glad to see you happy with a good product 😊. When I saw you tightening the nuts on the terminals, want to ask about the torque specs for those terminals? Many people at home may need to be careful not to over tight and cause damage.
I like that they are heavy duty case and terminals. I really liked that you showed us the cold temp cut off real cool. Thanks for your intelligence Will!!!
Don’t know if it will fit but I have used a Playmate cooler for a battery box, workout great. Gives a lot of protection, insulation. The only down side was had to drill through the thicker case , no big deal .
I like that they put thought into assembling packs in the design with the steel rod. The mounting of the bms always seems like an afterthought in these videos though. Next step after assuming the cells with a threaded rod is to nicely mount the bms, in my opinion. Also, it would be fun to cut one open, if you can do this safely! This is the most promising/professional solution for diy cell assembly. Thanks for the video.
I would not cut one open, as depending on make and type, the electrolyte can contain organofluorophosphates, some of which are insecticides and nerve agents. Google returns some interesting results!
@@fj40bryan New batteries probably safer, but this paper indicates that organofluorophosphates can be produced by electrolytic decomposition if the electrolyte is fluorinated. www.sciencedirect.com/science/article/abs/pii/S0021967319307393 I also wish I hadn't searched now!
I priced these batteries they are $120 per 100ah cell and $90 to ship to Indiana. $570 total (4 cells). The 100ah CALB batteries that you tested as good are only $480.28 w/tax (4 cells) with the buss bars & free shipping (60 days of course) I am sure these are really good cells but still $90 more per 12v battery. I did find out about Tariffs. It is a random chance that batteries from China will get snagged and marked for a tariff fee. They say to buy them in smaller lots and even have seller mark the packages as a gift then they will often ignore it. From what I seen most of the batteries like these on Aliexpress have free shipping (unless one requires fast shipping then a lot more of course)
Can you simply skip the battery case? Seems like all the important stuff is already covered in plastic. Plus you get the added benefit of good airflow. Now I would strap them down if they were in an RV or van. 😁
Dang! I love these batteries! Super rugged modular design with heavy-duty lugs. Perfect for a serious A class RV power bank. I'm sure they can be configured into 24 & 48 battery banks too, right? Oh, and Will, from working in the oil patch to cut all thread rod run a nut up to where you're going to cut, then cut with a hacksaw. Now back the nut off over the cut, and you fix the threads. If need be, a cheap triangle file will fix any minor burrs; one doesn't need a special tool. I don't see where one needs a case for these cells except for something that screws onto the top to contain the BMS. Can't wait for more video's on these cells.
Maybe you have addressed this before (sorry if so), but don't you suspect manufacturers are cherry picking batteries when they send you a batch? i.e. it's not a surprise you keep getting batteries with close voltage matches .. or do you order under a fake name and fake address across state lines and have a friend drop them off etc?
You don't need a deburring tool, thread a nut onto the rod at the point of cutting, then remove the nut (with a wrench if needed), the nut will deburr the end.
Instead of leaving an air gap between cells. How about fitting some flat plate aluminum that extends out both sides an inch or two. Thinking this would dissipate the heat more efficiently.
Hello Mr. Prowse I was just wondering if I could ask you a question about the Fortune LiFePO4 batteries in this video. I’m planning on building a 48v 19.2 kWh battery bank and I was just wondering if you would recommend these batteries for a system that large or if you would just go with Battle Born batteries. I did some ruff calculations and I would save roughly 5,000 if I built it myself and went with the Fortune but I’m not sure if it’s worth it for no warranty and I don’t know if the Fortune batteries would hold up over the long haul compared to the Battle Born. And if you would choose the Fortune batteries, Can you wire them up in parallel and then combine multiple packs in series to increase the battery bank capacity?. Also is it better to have multiple 48v cells wired in series or is it better to make smaller 12v cells wired in Parallel to get 48v and then wiring them in series Thank you for your time and all the work you put into your videos.
Really nice holders and accessories. Makes things so much better and nicer. The spacing between batteries is also nice. I would say the energy density is a bit lower than some other cells we have seen, but for stationary storage not a problem. Price also looks good. I see no fault in the design.
Heres a little old school tip that can save the price of a deburring tool. Before you cut the rod, thread on a couple of nuts that fit. After you cut the rod, unscrew the nuts and that will straighten out the threads. Nice video Will.
Just curious, what was your shipping on 4- 60Ah cells, or the (8) 4-60Ah, and 4-100Ah cells? The web site won't give you a shipping charge until you actually place an order and they have all your credit card information.
Hey Will, I am glad to see you reviewed these, as it turns out these are at least a year old, based on the review date. Other than those plastic end caps and those very Hardy terminals, the cell's appear to be the same as the newest ones, they're just about double the weight of the newest cells, and that made it hard for me to believe that these newest cells, were just too good to be true, as these newest cells are less than half the weight and size of the 100 ah cell's that I am replacing. And yes the ones that I am replacing are 13 years old, so I guess it's not impossible to believe that they could advance that much in 13 years, but what was a bit misleading is these cells from a year ago, for a 16S pack of them, the total weight is only 22 pounds lighter than my 13 year old pack but half the weight of the newest ones.
Hey dude, I appreciate all the info you put out there! I am going to buy everything I can through your affiliate links as I'm gearing up for a van build.
I purchased mine about two years ago, 32 cells at 24 volts. However, the plastic covers on mine did not have the holes for the threaded rods. Also, they were a bit cheaper then, understandable. P.S., purchased from the same company, great service.
Since this video, I recently purchased 16 Fortune 100A for a 48V build. They arrived and all were within a couple millivolts. 48V allows smaller wires and larger panels. Have to order most components online. Having trouble sourcing good BMS with low temp cutoff that is not prohibitively expensive. The one on Will's website is sold out. Looking at a Growatt since it has dual MPPT. Considering multiple separate inverters since I don't want them on 24/7. I have a separate cheap 12V 20W panel with old truck batteries for lights in the garage. Looking at larger solar panels to maximize utility.
Hi Will, I'm looking to build a 12v 400ah battery, maybe with 16 of these cells... they look good.. Can the 100A bms you used here work for me? Any more info on the wires you soldered to it and why?? thanks
Great video once again. With the form factor and ease of assembling packs these seem to be the best option out there. I have built two 12v CALB batteries but would like to see someone 3D print plastic connectors for top and bottom to enable easy assembly of CALB packs, rather than using clamps and wasting a truck load of assembly time. With a peak 6C for these fortune cells it's a no-brainer though for my next pack! Thanks for putting out this top quality info!
1:18 The gap between cells is not enough for convective air flow. You need a space >1" (~3 cm) before the air is able to flow to get any significant convective heat transfer.
Just a hint regarding the deburing. If you wind the nut past where you are cutting, then make the cut, then wind the nut off and it will clean the thread up using the nut.
Hey Will, Does someone make a bms to put 16 of these together to make a 48 volt battery? A bms with 16 leads? Also... if i just wanted to build a 12 volt battery like you did here.. can i hit it with a normal 12v battery charger? Do I have to have a 'special' charger to bring it up to full charge? Lovin' the vids and your thirst for knowledge. Learning is living. Teaching what you learn is fulfilling as I imagine you have discovered. All the best... Jim
Hey Will, another great video. Just wondering about the BMS's you used...I see the one you used for the 100ah is quite different than the one used for the 60ah.? Do they have low-temp cutoff? Thanks
Will, love your work and your review of these cells was sufficient for me to order USD3k worth of cells. There's some issues with delivery because of the demand from your review. I'm hopeful though that the supplier is ready for the demand that comes with your favourable reviews...
After I posted this video I ordered $1,200 more with my own money. I love these cells and now I'm building a 48 volt battery pack and everything works flawlessly. and yes, they have a large inventory but they're shipping department is pretty small. Might be delayed but it should get to you no problem. I'm pretty sure I'm going to make all of my future videos with these cells because I like them so much. I found out yesterday that they use these cells in underground mining equipment and electric trains. They are very durable and made to last.
Will, Can you make a video that explains when you can or cannot put a battery in SERIES? Some manufacturers don't allow it, and we don't know when it is OK or not for DIY batteries...
@Jason Bowman I suspect that the problem, has to do with the series connection looking more like a floating ground in between the batteries/BMSes. With two in series, if you had a way to interlink the two BMS units, they could probably sort it out fine, but without that, your voltages may be different between the two batteries, and that could cause all sorts of confusion. I believe this is why you have BMSes with a different number of balance leads, to handle different numbers of cells in your pack.
Will,. I look forward to hearing what the industry expert has to say. There has been a lot of ideas stated as fact but so far I have only heard one explanation that makes sense for limiting series banks. I really don't get limiting parallel banks
@@WillProwse seriously man, I can't think of a single issue to complain about. Between the two sizes and included busbars and different configuration options. This is has the least compromises of any battery system I have seen. It would be hard to choose anything else if a person is doing something permanent and impossible to justify other options for something Mobile (ie van, tiny house or mobile solar generator on wheels)
One whole chicken with some onions use zero or bottled water purity. Little salt and pepper (lots of other spices to taste but unnecessary for healthy. As meat falls off bone, (45-60 minutes) separate for other uses or to put back in soup. After most meat is off separate broth. Add More pure water to continue cooking then removing skin and cartilage and any other meat. Boil bones until satisfied all marrow is out. Trash skin and bones etc. this second boil will have little flavor but add to broth you now have medicinal chicken soup. Consume broth 3-5 ounces minimum. this established recipe should be the natural penicillin to keep you well. Take sections of it and add anything you want from rice to the chicken to vegetables such as carrots celery and you will have many meals, including chicken to put in your salad sandwiches or fry with breading! hope this helps, ....67 years old and have been successful in fighting colds for nearly 20 years now. enjoy
i'm curious about the vendor, Electric Car Parts Company. Did they contact you or did you just buy some inventory without warning them like the ali express purchases? I noticed their 'about me' and 'blog' sections of their website don't actually exist, and was curious.
I run our house on 16 battleborns and will do our RV system next with either 2 or 4- haven't decided yet. But I would say this new design battery cell is definitely on par with the Battleborn - at least as far as we can tell from just one review from will. They seem to be engineered very well, a thoughtful design that is easy to work with, safe to use and simple to assemble. I may try some and build a bank for the RV but I must say - it is nice knowing that my battleborns have a good warranty. Also they have the best customer service that I've ever experienced...
I see you use a bench top power supply to do your charging.Could you do a short video on how to charge LifePo4 batterieswith a adjustable voltage/current power supply?
Functionality of Cc/cv power supplies are very similar to benchtop power supplies. On both you set a voltage and max current to be drawn. It’s just that you have more flexibility and convenience on a benchtop powersupply.
Hi Will, I think I have found the manufacture of these cells are you interested in ordering any cells,? they are minus the plastic molding, but I have asked the manufacture if he can help source the supplier of these moldings!
I use my small bench grinder for deburring. Simply hold the rod very lightly to the face of the fine grit wheel at about a 45 degree angle and rotate it. The key is to use very little force. Takes about 2 seconds.
I have looked over your previous vidoes and have been watching for around a year. I would like to know if you could up load a video of using 2 or more 24v batteries (ones that you make out of 8 3.2v batteries) for a system. What is the best way to use a bms; one bms for each battery setup and another bms to those individual bms's, or one bms that can balance more than 2 24v batteries (once again ones that you make out of 8 3.2v batteries). Best way to charge and other information that is important to know or look for..?
R. Kane, You need to do more research on your own for basic questions such as this. If you find something specific that you are unable to solve, then ask questions.
@@geraldhenrickson7472 I have done a lot of research and I get mixed information on bigger battery systems. But I am always randomly looking at more info and videos. Also I feel like I can trust his videos more than others. :)
This kit they come with is the most awesome bit about it. Makes the whole build so neat and tidy and auto adds in the cooling gap. Is this kit available for other battery sizes and shapes?
I like these. Cost wise, they are competitive with other formats. I was looking at the 25ah form factor. A 72v 25ah pack would come in a bit under $600. The salvaged pouch cells I just ordered are $300 for 60 cells - 20s3P - 24-27ah @80v. And I still have to build the pack and design an enclosure. While both can be built without welding or soldering, if I were using the Fortune cells, I would not have to fabricate anything besides a watertight enclosure. And refactoring the pack would be like playing with legos. Buy some more cells - hook em up series to up voltage. Next month, buy some more and refactor into a 2P pack. The 25AH units are small enough to make a pretty powerful pack. And with the robust connectors, one is not limited to a monolithic pack. You could easily have some cells behind the seat or in panniers and just cable the connections as required, using heavy gauge copper cables with ring connectors. Weight is very close to where I think I'll end up with the pouch cells.
Hi Anton, I'm a solar, lithium battery ROOKIE! and I'm hoping you can answer my question if you don't mind. In this video of Wills he has shown us two different cells, one is 60aph cell and the other is 100aph cell correct? I will be building a van conversion in the future and I've been looking at the Battel born 100aph battery. For the amount of space the 100aph BB would use up in the van I should be able to build a 400aph-600aph battery in the same space using the 4-6 100aph cell Will has just reviewed in this video? am I understanding this correctly? I would ask Will this question but the guy has 300,000 subscribers. If you can clarify this for me that would be great. Thank you.
Tax Slave 4 of those cells hooked together in series make 12volts and 100ah. They are 3.2volt cells 100ah. The same website that sells these cells have a 12volt battery making 400ah for $1700! That’s the best price per AH around.
Mike Mead I’ve been wanting to make the change from Flooded Lead Acid to Lithium ion phosphate! I’m over the discharge recharge rate of the FLA batteries I need new blood. The Battle Borns I’ve had my eye on for a little while, then Will will bust out a video on another option, then he drops a video on these and so far these look like the best made 🤔 single cells that can be put together to make the 12v battery that I need, and I was just thinking hey these might be the ones and possibly cheaper!!! 🤔
@Mike Tipping I think Stephen Otto just wants to sound like he knows what he's talking about. Anyone who knows even a little bit about this stuff knows that it's all dependent on the needs of the project. Obviously you would NOT want to go 24v if all the appliances that you're trying to run are 12v and you just want a simple direct-powered setup, without any step-down converters & all the extra wiring that goes along with it. And also, you can easily make a 24v setup with these cells if that is your goal, so his comment just seems...pointless. At the very least, incomplete.
Nice video Is there anything you will dislike about these batteries ? The cost. Mr Prowse, Pleace include the Watt per Cubic inch when comparing batteries. What Battery is the most compact ? The 110AH are $120.00 and they have 230 AH cells for $225.00
That would be 40 cells for about 13kWh and a price of around $4k,plus $500 for a decent bms, cables, inverter and lots of time. You could just get a Tesla powerwall for about the same price and it would just work from day 1.
@@kktab3919 It's only a suggestion to consider options if available. It can be fun and satisfying building something yourself instead of just buying a box, but it does come with a guarantee that it won't burn your house to the ground if you screw up. Self-build batteries may also invalidate home insurance unless you can get it certified, so there's that to consider too. Personally I accept the risk with my own batteries, but I don't have a house or a family to consider.
I could care less about the weight and size because it would be stationary (for solar storage) I'm buying some now, great video and very informative, God bless you and your family.
Funny how I first came across these batteries less than 24 hours ago while browsing the electriccarparts website. They stood out to me. And voila, few hours later you upload this video lol.
WOW.... I think I may have found a battery to power up my HAM radios out in the field. My radio draws a maximum of 23a. I think that a 16 volt battery, with a buck converter to 13.8 or 12 volts is the ticket.
@@JT-py9lv A fully charged LiFePO4 cell is 3.60, resting voltage is around 3.35, x 4 = 13.4. You said you could use 13.8 or 12 volts, 4 cells would put you in that range.
Avoid anything that has a switching module / PWM and similar. It likely would create a lot of HF noise. Keep it simple, just a 4 cell battery directly hooked to your receiver. The discharge voltage is pretty flat from 100% down to 10% or so, no need to regulate that.
For the smaller battery, are they 60Ah each? Or 60Ah with all 4 combined? Same question for the 100Ah battery. Also, what size are the threaded rods? I went to the electric car company website link you provided and it states the batteries don't come with the threaded rods (I'm assuming they're talking about the rods that hold the battery case together.)
First time I hear you mention Sol-Ark :) Looks like 4 cells only cost $460, plus shipping and BMS. That’s like half the price of a BB. Looking forward to more tests with this battery
Robert Hayden but also the more cells you buy the cheaper they get. 1-4 cells at $115 each but 98 cells plus at $98 each. That $17 difference per cell should easily cover shipping and then some.
HI Will! These do look like a great form factor and great for DIY batteries. One note, you can clean up the threads on the end of cut threaded rod with a file or a grinder disk, rather than needing to get the specialized tool. No criticism, just hopefully a helpful tip! Would something like this be ok for a vehicle replacement battery?
Please come back to post once you have received them. Sometimes these companies make special samples for youtubers and then when we purchase off the recommendations we get the garbage.
I should also add, these are heavy compared to other Al cased cells, but they are actually LIGHTER, and take up less volume, than many other lifepop4 prismatic cell case variants, such as sinopoly/winston cells. But compared to other Al case cells, they are off by 50wh/kg, which is substantial. So they are not actually "heavy" for being lifepo4, but as I said in the video, they are heavy as an Al cased cell.
Quick specific energy comparison from my testing:
Other Al case Grade A prismatic Cells: 159-163Wh/Kg
Fortune Cells: 106-110Wh/Kg
Sinopoly/Winston etc: 90-110Wh/Kg
So as always, it's relative. Considering the durability of these cells, it is not surprising that they weigh more than the tiny terminal Al case cells. It is WELL worth the increased weight and decreased volumetric density, in my opinion.

I was starting to feel like there was not a suitable contender for the battery I'm thinking of building, but now there is, and I'm feeling happier.
Has anybody used these cells ? I would be interested to see how they last in prolonged use.
Can you use these to build 6v batteries for golf carts? Or Valence batteries? Want to get away from standard batteries for my 36v Ezgo cart. I appreciate all the videos. Learning a lot.
Considering Al case Grade A prismatic cells are lighter and usually cheaper? Why would you still want to buy Sinopoly/Winston cells? For their durability? For them being more established "brands"? I will buy 300-400 Ah batteries in the near future and it's really tempting to buy the Chinese Al case cells cause of their price. On the other hand, Winston has a distributor in the EU and it feels like I would be taking less of a chance if I go for Winston.
@@Warzbag340 I think the biggest reason is that they are trusted. Personally, I would go with the newer aluminum cased cells because of improved manufacturing methods. But I'm sure the older folks will disagree with me because they used older tech cells for longer.
@@georgepaquette4202 sure
Very nice! The plastic shrouds are really well thought out for any shape imaginable, and make it easy to swap out tired cells.
Tip for cutting threaded rod - put a nut on it first before cutting, then unscrew the nut to tidy the thread, then you can file the end burr for easy use.
Also, don't use bolt cutters. Instead, use a saw or cut off wheel.
@@D2O2 smart idea. I actually saw a video of the deburring tool and cringed at using a nut for all the cuts I had to do. The deburring tool took seconds and I didn't have to position the nut before every cut. Or spin it down a 2 foot rod. The deburring tool saved a lot of time and worked great. But yeah, a nut could work
You guys should try that tool. Super convenient.
@@WillProwse The tool is great if you're doing many of them a day, but otherwise it's just a thing you have to spend time looking for at the bottom of one of the toolboxes you forgot about!
you beat me to it ,
If i could be as excited as this guy about life as he is about batteries, id be very happy.
LOL
The only thing stopping you is your self..
If we had a ranking system of who's better off in life you would rank higher then you think.
Will is pure heart and make him happy
If I had half his knowledge I'd be happy...
Haha
I know nothing about battery systems, I came here by accident, but I love your enthusiasm, and now I find myself learning stuff about batteries. Thanks.
I used these Cells to build a 48V 300Ah battery (48 cells 3P16S) in combination with 2 MPP 5Kw inverters and a Daly BMS 16S 100/200A. It works great and I power my whole house 24/7 with it. (I live in the Philippines so no lacking of Sunlight) Actually it was Will's recommendation what made me use this cells. I ordered it in China directly from the Manufacturer for only $50 per cell.
Sir, can I ask for a link so that I can order directly from the supplier? Is that possible, sir?
WOW! Who cares if they are big and heavy they look great! And as a newbie I really appreciate the user friendly nature of these. It's like you almost snapped them together like Legos!😁👍❤
Will, PLEASE please please build a 400 amp hour 12 volt and 24 volt DIY systems? Preferably with these batteries hooked to both solar and a vehicle 12 volt system. Few of us can afford 4K for Battle Born, so it would be a big help.
Thanks for the great content!
I would like this also.
+1
I'm hoping to see this type of build for my RV. Thank you in advance.
watch my RUclips
I would also GREATLY value a build of this nature....
Will, I have been using the 100AH Fortune cells for about 2 years living fulltime in an all electric RV (no propane). I run a 200AH 48V bank with 2 Victron Quattro (split 240V). I have hit them with some pretty hefty loads and they have performed great. BTW great vids, keep 'em coming
Thanks for letting us know that they can be used in both serial and parallel configurations.
Awesome thanks for chiming in so helpful. That's like $5k in batteries alone isn't it?
How many 200Ah 48 volts batteries do you use?
@@ThundarrZ It ran about $4K with tax and duty. I used the bottom balance method with a powerlab 8.
@@williamkunte5361 I used 100AH cells (3.2V), 16 in a pack (48V) with 2 packs total (200AH)
Will! If you haven’t done a video on it, please do a quick tutorial on how to solder. I have watched other videos, but I am still not good. I’m optimistic that with your clear teaching style, I could improve with the info you would teach!
Your enthusiasm is infectious ..... Keep up the good work ....
When I saw those rods I thought,
“hang on a minute! No will prose review is complete without him taping something together??”
Luckily he had to attach the BMS to the pack...
Hi Will. For the threaded rod....
Put your nut on the rod before you cut it , then unthread the nut past the cut and the nut will straighten the threads.
Also if you cut using a dremel tool and cutoff discs , it cuts very clean but put the nut on before you cut , incase .
This is turning into my favourite channel, so interesting and learning heaps, also great to finally understand Americans using the Metric system,
Mine too. I am an Electrical Engineer,
but have learned more about solar from Will than any schooling.
I understand power, volts amps, etc,
but Will shows us the products we want and the ones we don't.
Thanks for the video, Will. Thanks for all the effort you put into all your tests. I will have a look for the batteries in Australia.
hi there, the batteries are manufactured by our factory, welcome to contact me for more details. whatsapp 0086 18963643619
I love your videos as one who designed and installed a small remote location solar system. Eleven months ago we had to replace our batteries and wanted to go Lithium but the batteries will be in a cold environment for several months. So, we went with AGM's. At the time I was unaware of a low temp cutoff in fact I don't think there were hardly any BMS's or battery with one. That is how far things have come in just one year! If I had to do it over today I would have no problem putting in a Lithium battery system knowing I could incorporate a reliable BMS with low temp cutoff. The only problem I am having at the moment is what battery would I buy? In your series of evaluating different batteries each time you review a battery and give it a thumbs up I think that is the battery I would buy. Then you do another battery evaluation, like the one above, and my mind is changed again!!! Thanks for all the reviews you do. I have learned a ton and wish I would have had this kind of knowledge 7 years ago when I first setup the system.
John Strein make a list of top 3 batteries and roll a dice. Murphy’s Law says there will be a better cheaper battery the day your order arrives in the mail.
@@4philipp Yup, that's the way it goes.
It’s like buying a laptop.... the minute u buy it it’s out of date...
Dig a hole for a battery pit. Check your location for where the frost line is. That'll keep the batteries at 32F.
Are these still the best deal for LifeP04 batteries? This video is 1 year old.
I understand about half of what you say in these videos, but I am understanding more the more I watch 😅 Thanks to your videos, I installed my first van system using your least favorite battery, 2 AGM 100ah Deep Cycle Batteries. But in the future I would love to build my own lithium system from cells. So keep on with these awesome videos.
it's addictive
Me too at beginning but catching more and more.
Those are by far the best battery configuration I have seen yet. Size and weight is an easy compromise, when it comes to stacking.
Thanks again Will! Your videos have given me the confidence to design and build my own system!
Will great video and very informative. Love the fact you put in lots of sources for all materials. Thanks!
For my application, I Really don't care if they are heavy or big in size, it's for my solar bank and never moved so weight is not important! Good video!
Thanks for the great evaluation. You have a wonderful channel. I'm buying 96 of these cells tomorrow to build a 144 VDC, 200AH battery bank for electric propulsion on my sailboat. This bank will also cross-charge my 24 and 12 VDC banks.
Thank you Will, glad to see you happy with a good product 😊. When I saw you tightening the nuts on the terminals, want to ask about the torque specs for those terminals? Many people at home may need to be careful not to over tight and cause damage.
I like that they are heavy duty case and terminals. I really liked that you showed us the cold temp cut off real cool. Thanks for your intelligence Will!!!
Don’t know if it will fit but I have used a Playmate cooler for a battery box, workout great. Gives a lot of protection, insulation. The only down side was had to drill through the thicker case , no big deal .
I prefer the Colman coolers with wheels:)
@@chucksw1 If I had one ... that’s probably what I would have used as well , wheels are a wonderful thing :-)
Love your descriptions of these batteries. So are these best to get for solar systems.
Best battery so far for the sailboat people, because of the strong construction. Do a drop test Will.. ;)
I'm impressed with these cells, thanks for doing all the research for us! Your videos rock!
Looks like it was designed by an engineer who took some pride in their work. 👍
@bowblizz They were designed by the engineer who actually OWNS the company. LOL.
I like that they put thought into assembling packs in the design with the steel rod. The mounting of the bms always seems like an afterthought in these videos though. Next step after assuming the cells with a threaded rod is to nicely mount the bms, in my opinion. Also, it would be fun to cut one open, if you can do this safely!
This is the most promising/professional solution for diy cell assembly. Thanks for the video.
I would not cut one open, as depending on make and type, the electrolyte can contain organofluorophosphates, some of which are insecticides and nerve agents.
Google returns some interesting results!
Andy Lee Robinson
I’m curious if the build quality is as nice on the inside as it appears on the outside but Yikes that’s sounds like a bad idea then!
@@fj40bryan New batteries probably safer, but this paper indicates that organofluorophosphates can be produced by electrolytic decomposition if the electrolyte is fluorinated.
www.sciencedirect.com/science/article/abs/pii/S0021967319307393
I also wish I hadn't searched now!
Im exited,best batteries so far. Perfect for small offgrid system!
I priced these batteries they are $120 per 100ah cell and $90 to ship to Indiana. $570 total (4 cells). The 100ah CALB batteries that you tested as good are only $480.28 w/tax (4 cells) with the buss bars & free shipping (60 days of course) I am sure these are really good cells but still $90 more per 12v battery. I did find out about Tariffs. It is a random chance that batteries from China will get snagged and marked for a tariff fee. They say to buy them in smaller lots and even have seller mark the packages as a gift then they will often ignore it. From what I seen most of the batteries like these on Aliexpress have free shipping (unless one requires fast shipping then a lot more of course)
Can you simply skip the battery case? Seems like all the important stuff is already covered in plastic. Plus you get the added benefit of good airflow. Now I would strap them down if they were in an RV or van. 😁
Dang! I love these batteries! Super rugged modular design with heavy-duty lugs. Perfect for a serious A class RV power bank. I'm sure they can be configured into 24 & 48 battery banks too, right? Oh, and Will, from working in the oil patch to cut all thread rod run a nut up to where you're going to cut, then cut with a hacksaw. Now back the nut off over the cut, and you fix the threads. If need be, a cheap triangle file will fix any minor burrs; one doesn't need a special tool. I don't see where one needs a case for these cells except for something that screws onto the top to contain the BMS. Can't wait for more video's on these cells.
Maybe you have addressed this before (sorry if so), but don't you suspect manufacturers are cherry picking batteries when they send you a batch? i.e. it's not a surprise you keep getting batteries with close voltage matches .. or do you order under a fake name and fake address across state lines and have a friend drop them off etc?
You don't need a deburring tool, thread a nut onto the rod at the point of cutting, then remove the nut (with a wrench if needed), the nut will deburr the end.
Instead of leaving an air gap between cells. How about fitting some flat plate aluminum that extends out both sides an inch or two. Thinking this would dissipate the heat more efficiently.
Great idea!
How about with some thermal grease?
Yeah... Fins like motorcycle cylinders or airplane cylinders... "cool" idea... pun intended.
Hello Mr. Prowse
I was just wondering if I could ask you a question about the Fortune LiFePO4 batteries in this video.
I’m planning on building a 48v 19.2 kWh battery bank and I was just wondering if you would recommend these batteries for a system that large or if you would just go with Battle Born batteries. I did some ruff calculations and I would save roughly 5,000 if I built it myself and went with the Fortune but I’m not sure if it’s worth it for no warranty and I don’t know if the Fortune batteries would hold up over the long haul compared to the Battle Born.
And if you would choose the Fortune batteries, Can you wire them up in parallel and then combine multiple packs in series to increase the battery bank capacity?.
Also is it better to have multiple 48v cells wired in series or is it better to make smaller 12v cells wired in Parallel to get 48v and then wiring them in series
Thank you for your time and all the work you put into your videos.
I was beginning to think Will's evil twin took his place, until the tape came out ;o)
Haha!!
Really nice holders and accessories. Makes things so much better and nicer. The spacing between batteries is also nice. I would say the energy density is a bit lower than some other cells we have seen, but for stationary storage not a problem. Price also looks good. I see no fault in the design.
The way we remove burs is to thread two nuts on first then cut and back the nuts back over the thread. It recuts threads.
Good way to wreck threads on your rod and nut
Heres a little old school tip that can save the price of a deburring tool. Before you cut the rod, thread on a couple of nuts that fit. After you cut the rod, unscrew the nuts and that will straighten out the threads. Nice video Will.
Just curious, what was your shipping on 4- 60Ah cells, or the (8) 4-60Ah, and 4-100Ah cells? The web site won't give you a shipping charge until you actually place an order and they have all your credit card information.
Also says you can just email them.
I paid $55 US
25-100AH shipped from Utah to MN was $400.
Hey Will, I am glad to see you reviewed these, as it turns out these are at least a year old, based on the review date. Other than those plastic end caps and those very Hardy terminals, the cell's appear to be the same as the newest ones, they're just about double the weight of the newest cells, and that made it hard for me to believe that these newest cells, were just too good to be true, as these newest cells are less than half the weight and size of the 100 ah cell's that I am replacing. And yes the ones that I am replacing are 13 years old, so I guess it's not impossible to believe that they could advance that much in 13 years, but what was a bit misleading is these cells from a year ago, for a 16S pack of them, the total weight is only 22 pounds lighter than my 13 year old pack but half the weight of the newest ones.
Hey dude, I appreciate all the info you put out there! I am going to buy everything I can through your affiliate links as I'm gearing up for a van build.
Excellent review! Those cells look promising! Putting together a quality 100ah 12v for about 500? That’s almost a game changer!
Great video Will. Is this the same as the SimpliPhi? This is what I have been waiting for with a Sol-Ark 12k
I purchased mine about two years ago, 32 cells at 24 volts. However, the plastic covers on mine did not have the holes for the threaded rods. Also, they were a bit cheaper then, understandable. P.S., purchased from the same company, great service.
hi there, please contact whatsapp 0086 18963643619 if you are still interested in these batteries.
Dangling those +/- leads nice and close to each other :D
*anxiety intensifies*
Since this video, I recently purchased 16 Fortune 100A for a 48V build.
They arrived and all were within a couple millivolts.
48V allows smaller wires and larger panels.
Have to order most components online.
Having trouble sourcing good BMS with low temp cutoff that is not prohibitively expensive.
The one on Will's website is sold out.
Looking at a Growatt since it has dual MPPT.
Considering multiple separate inverters since I don't want them on 24/7.
I have a separate cheap 12V 20W panel with old truck batteries for lights in the garage.
Looking at larger solar panels to maximize utility.
Hi Will, I'm looking to build a 12v 400ah battery, maybe with 16 of these cells... they look good.. Can the 100A bms you used here work for me? Any more info on the wires you soldered to it and why?? thanks
Great video once again. With the form factor and ease of assembling packs these seem to be the best option out there. I have built two 12v CALB batteries but would like to see someone 3D print plastic connectors for top and bottom to enable easy assembly of CALB packs, rather than using clamps and wasting a truck load of assembly time. With a peak 6C for these fortune cells it's a no-brainer though for my next pack! Thanks for putting out this top quality info!
1:18 The gap between cells is not enough for convective air flow. You need a space >1" (~3 cm) before the air is able to flow to get any significant convective heat transfer.
Fan cooling with temp sensor switch?
Just a hint regarding the deburing. If you wind the nut past where you are cutting, then make the cut, then wind the nut off and it will clean the thread up using the nut.
Put the nuts on first then cut the rod, and take the nuts off to clean the threads. Nice job BTW.
Hey Will, Does someone make a bms to put 16 of these together to make a 48 volt battery? A bms with 16 leads? Also... if i just wanted to build a 12 volt battery like you did here.. can i hit it with a normal 12v battery charger? Do I have to have a 'special' charger to bring it up to full charge? Lovin' the vids and your thirst for knowledge. Learning is living. Teaching what you learn is fulfilling as I imagine you have discovered. All the best... Jim
Will, we love your content! Would you please list your test equipment under your camera equipment list?
Oh good idea. Will have to make a video about what I use :D
Show us how to use each piece too, nothing sadder than a hobbyist who doesn't know how to use an instrument to trouble shoot a problem.
Hey Will, another great video. Just wondering about the BMS's you used...I see the one you used for the 100ah is quite different than the one used for the 60ah.? Do they have low-temp cutoff? Thanks
According to an e-mail I received from Electric Car Parts Company, “The Factory will warranty them for 2 years”.
Good morning looks like a really nice strong battery assembly at last well done.
Will, love your work and your review of these cells was sufficient for me to order USD3k worth of cells. There's some issues with delivery because of the demand from your review. I'm hopeful though that the supplier is ready for the demand that comes with your favourable reviews...
After I posted this video I ordered $1,200 more with my own money. I love these cells and now I'm building a 48 volt battery pack and everything works flawlessly. and yes, they have a large inventory but they're shipping department is pretty small. Might be delayed but it should get to you no problem. I'm pretty sure I'm going to make all of my future videos with these cells because I like them so much. I found out yesterday that they use these cells in underground mining equipment and electric trains. They are very durable and made to last.
These batteries are awesome so flexible. Your channel is awesome.
Will, Can you make a video that explains when you can or cannot put a battery in SERIES? Some manufacturers don't allow it, and we don't know when it is OK or not for DIY batteries...
Yes, going to have a industry professional interviewed to answer that
@Jason Bowman I suspect that the problem, has to do with the series connection looking more like a floating ground in between the batteries/BMSes. With two in series, if you had a way to interlink the two BMS units, they could probably sort it out fine, but without that, your voltages may be different between the two batteries, and that could cause all sorts of confusion. I believe this is why you have BMSes with a different number of balance leads, to handle different numbers of cells in your pack.
Will,. I look forward to hearing what the industry expert has to say. There has been a lot of ideas stated as fact but so far I have only heard one explanation that makes sense for limiting series banks. I really don't get limiting parallel banks
Will, please build a 48 volt bank using these batteries, but make it a 32 battery 200Ah bank.
These batteries are amazing. Idk if a better solution is out there. So clean.
Right?! Incredible
@@WillProwse seriously man, I can't think of a single issue to complain about. Between the two sizes and included busbars and different configuration options. This is has the least compromises of any battery system I have seen. It would be hard to choose anything else if a person is doing something permanent and impossible to justify other options for something Mobile (ie van, tiny house or mobile solar generator on wheels)
You're getting a cold. I can hear it. Chicken soup.
One whole chicken with some onions use zero or bottled water purity. Little salt and pepper (lots of other spices to taste but unnecessary for healthy. As meat falls off bone, (45-60 minutes) separate for other uses or to put back in soup. After most meat is off separate broth. Add More pure water to continue cooking then removing skin and cartilage and any other meat. Boil bones until satisfied all marrow is out. Trash skin and bones etc. this second boil will have little flavor but add to broth you now have medicinal chicken soup. Consume broth 3-5 ounces minimum. this established recipe should be the natural penicillin to keep you well. Take sections of it and add anything you want from rice to the chicken to vegetables such as carrots celery and you will have many meals, including chicken to put in your salad sandwiches or fry with breading! hope this helps, ....67 years old and have been successful in fighting colds for nearly 20 years now. enjoy
i'm curious about the vendor, Electric Car Parts Company. Did they contact you or did you just buy some inventory without warning them like the ali express purchases? I noticed their 'about me' and 'blog' sections of their website don't actually exist, and was curious.
Will, would you say that these batteries would be competitive to adding 12 volt Battle Borns to an RV?
I run our house on 16 battleborns and will do our RV system next with either 2 or 4- haven't decided yet.
But I would say this new design battery cell is definitely on par with the Battleborn - at least as far as we can tell from just one review from will.
They seem to be engineered very well, a thoughtful design that is easy to work with, safe to use and simple to assemble.
I may try some and build a bank for the RV but I must say - it is nice knowing that my battleborns have a good warranty. Also they have the best customer service that I've ever experienced...
Very clean, simple and easy cells to manage.
5:25 what soldering iron are you using Will?
@bowblizz winner winner chicken dinner like eevblog would say.
You should check out industrial velcro. It would make mounting the BMC to the battery easy. Industrial velcro is incredibly strong.
I see you use a bench top power supply to do your charging.Could you do a short video on how to charge LifePo4 batterieswith a adjustable voltage/current power supply?
Functionality of Cc/cv power supplies are very similar to benchtop power supplies. On both you set a voltage and max current to be drawn. It’s just that you have more flexibility and convenience on a benchtop powersupply.
Ive been looking everywhere for Info on alternator charging finally someone addressed that Thank you
Hi Will, I think I have found the manufacture of these cells are you interested in ordering any cells,? they are minus the plastic molding, but I have asked the manufacture if he can help source the supplier of these moldings!
I have the same BMS you use with the 100Ah battery. Did you use the standard settings or did you customize them in the app?
It'd be nicer if they tapped the bus bars for the bms connections.
I use my small bench grinder for deburring. Simply hold the rod very lightly to the face of the fine grit wheel at about a 45 degree angle and rotate it. The key is to use very little force. Takes about 2 seconds.
I have looked over your previous vidoes and have been watching for around a year. I would like to know if you could up load a video of using 2 or more 24v batteries (ones that you make out of 8 3.2v batteries) for a system. What is the best way to use a bms; one bms for each battery setup and another bms to those individual bms's, or one bms that can balance more than 2 24v batteries (once again ones that you make out of 8 3.2v batteries). Best way to charge and other information that is important to know or look for..?
R. Kane, You need to do more research on your own for basic questions such as this. If you find something specific that you are unable to solve, then ask questions.
@@geraldhenrickson7472 I have done a lot of research and I get mixed information on bigger battery systems. But I am always randomly looking at more info and videos. Also I feel like I can trust his videos more than others. :)
R Kane we have made video
This kit they come with is the most awesome bit about it. Makes the whole build so neat and tidy and auto adds in the cooling gap.
Is this kit available for other battery sizes and shapes?
He says this is the first time he has been excited in months ..hahahaha.
Also: *"these nuts"*
Yeah I caught that too 😲😜😇😏
I like these.
Cost wise, they are competitive with other formats.
I was looking at the 25ah form factor.
A 72v 25ah pack would come in a bit under $600.
The salvaged pouch cells I just ordered are $300 for 60 cells - 20s3P - 24-27ah @80v.
And I still have to build the pack and design an enclosure.
While both can be built without welding or soldering, if I were using the Fortune cells, I would not have to fabricate anything besides a watertight enclosure.
And refactoring the pack would be like playing with legos.
Buy some more cells - hook em up series to up voltage.
Next month, buy some more and refactor into a 2P pack.
The 25AH units are small enough to make a pretty powerful pack.
And with the robust connectors, one is not limited to a monolithic pack.
You could easily have some cells behind the seat or in panniers and just cable the connections as required, using heavy gauge copper cables with ring connectors.
Weight is very close to where I think I'll end up with the pouch cells.
I think this this are the cell's for my next project..
Hi Anton, I'm a solar, lithium battery ROOKIE! and I'm hoping you can answer my question if you don't mind. In this video of Wills he has shown us two different cells, one is 60aph cell and the other is 100aph cell correct? I will be building a van conversion in the future and I've been looking at the Battel born 100aph battery. For the amount of space the 100aph BB would use up in the van I should be able to build a 400aph-600aph battery in the same space using the 4-6 100aph cell Will has just reviewed in this video? am I understanding this correctly? I would ask Will this question but the guy has 300,000 subscribers. If you can clarify this for me that would be great. Thank you.
Tax Slave 4 of those cells hooked together in series make 12volts and 100ah. They are 3.2volt cells 100ah. The same website that sells these cells have a 12volt battery making 400ah for $1700! That’s the best price per AH around.
These look great and relatively easy to assemble. Looking forward to seeing you do a 48V with them.
John Hutchins we have done video for 24v and 48v
$115 per cell needing 4 to make a 12 volt system seems like a pretty decent price point for a 12 volt Lifepo4 battery that is 100 AH
Seeinya traveler after getting the bms and four cells would it be as capable as the 100ah battleborns? And cheaper ?
But if you’re doing DIY, you’ve gotta go 24v.
Mike Mead I’ve been wanting to make the change from Flooded Lead Acid to Lithium ion phosphate! I’m over the discharge recharge rate of the FLA batteries I need new blood. The Battle Borns I’ve had my eye on for a little while, then Will will bust out a video on another option, then he drops a video on these and so far these look like the best made 🤔 single cells that can be put together to make the 12v battery that I need, and I was just thinking hey these might be the ones and possibly cheaper!!! 🤔
@@PaDutchRunner why?
@Mike Tipping
I think Stephen Otto just wants to sound like he knows what he's talking about.
Anyone who knows even a little bit about this stuff knows that it's all dependent on the needs of the project.
Obviously you would NOT want to go 24v if all the appliances that you're trying to run are 12v and you just want a simple direct-powered setup, without any step-down converters & all the extra wiring that goes along with it.
And also, you can easily make a 24v setup with these cells if that is your goal, so his comment just seems...pointless. At the very least, incomplete.
Nice video Is there anything you will dislike about these batteries ? The cost. Mr Prowse, Pleace include the Watt per Cubic inch when comparing batteries. What Battery is the most compact ?
The 110AH are $120.00 and they have 230 AH cells for $225.00
I could ultimately see building a 1000 Amp Hour 48 Volt system with these. With a 6KW Solar Array, I could RUN MY HOUSE!
That would be 40 cells for about 13kWh and a price of around $4k,plus $500 for a decent bms, cables, inverter and lots of time.
You could just get a Tesla powerwall for about the same price and it would just work from day 1.
@@ahaveland time for you to go make your own sandwich and leave his alone
@@kktab3919 It's only a suggestion to consider options if available. It can be fun and satisfying building something yourself instead of just buying a box, but it does come with a guarantee that it won't burn your house to the ground if you screw up.
Self-build batteries may also invalidate home insurance unless you can get it certified, so there's that to consider too.
Personally I accept the risk with my own batteries, but I don't have a house or a family to consider.
@@kktab3919 Pretty useless unless I can get them at home depot or amazon
Andy Lee Robinson are you sure that’s only 40 cells? He’ll need 16 for a 100amp 48v battery. So at 1000amps that’s 160 cells.
I could care less about the weight and size because it would be stationary (for solar storage)
I'm buying some now, great video and very informative, God bless you and your family.
Could you make your own ‘generator’ using these batteries and sourcing a case, BMS, etc?
Jonathan Sailer check out earlier videos. You will find a plethora of information!
Funny how I first came across these batteries less than 24 hours ago while browsing the electriccarparts website. They stood out to me. And voila, few hours later you upload this video lol.
we have upgraded our battery to 510AH thanks to your advice you can see the motorhome on youtube search: 4x4 Motor home SLRV Commander
These cells are pretty spiffy. Especially with the endcaps & the provision to bolt them together. Excellent find!
WOW.... I think I may have found a battery to power up my HAM radios out in the field. My radio draws a maximum of 23a. I think that a 16 volt battery, with a buck converter to 13.8 or 12 volts is the ticket.
JT 6188 great idea to use on cb in wilderness too.
Why not just use a 4 cell battery which would be 13.4 volts instead of a buck converter which would waste energy?
@@JRP3 Well, when I went to school, 3.2x4 = 12.8 - or am I missing something ?
@@JT-py9lv A fully charged LiFePO4 cell is 3.60, resting voltage is around 3.35, x 4 = 13.4. You said you could use 13.8 or 12 volts, 4 cells would put you in that range.
Avoid anything that has a switching module / PWM and similar. It likely would create a lot of HF noise. Keep it simple, just a 4 cell battery directly hooked to your receiver. The discharge voltage is pretty flat from 100% down to 10% or so, no need to regulate that.
For the smaller battery, are they 60Ah each? Or 60Ah with all 4 combined? Same question for the 100Ah battery. Also, what size are the threaded rods? I went to the electric car company website link you provided and it states the batteries don't come with the threaded rods (I'm assuming they're talking about the rods that hold the battery case together.)
First time I hear you mention Sol-Ark :)
Looks like 4 cells only cost $460, plus shipping and BMS. That’s like half the price of a BB.
Looking forward to more tests with this battery
Guess it depends on the shipping costs.
Robert Hayden but also the more cells you buy the cheaper they get. 1-4 cells at $115 each but 98 cells plus at $98 each. That $17 difference per cell should easily cover shipping and then some.
@@4philipp Sure, but if shipping kills it, then it doesn't matter. You have to look at the whole package, not just the listed cost-per-item.
Robert Hayden I think it’s reasonable but haven’t seen any actual numbers
@@4philipp $80 for UPS from Salt Lake to Washington state for 4 100 AH cells. Hope this helps.
Put the nut on first, then cut the rod. Unscrew the nut and it will form the thread back to where they need to be.
Great product!
Run a nut on the long bolts before you cut it . Back off the nut. Whaaalaa deeburd.
HI Will! These do look like a great form factor and great for DIY batteries. One note, you can clean up the threads on the end of cut threaded rod with a file or a grinder disk, rather than needing to get the specialized tool. No criticism, just hopefully a helpful tip! Would something like this be ok for a vehicle replacement battery?
Please do a 24 volt mobile system with those batteries 🔋
“PLEASE “‘!!!
Over50Nomads please watch my video for 24v and 48v
Wow! what a well packaged integrative expandable adaptable product...
Thanx Will for your unbiased pragmatic reviews.
I really like these cells. Thank you.
Thanks for this Will. I've already order my cells, but this give me an ideal of how to secure them. Awesome!
Please come back to post once you have received them. Sometimes these companies make special samples for youtubers and then when we purchase off the recommendations we get the garbage.
Where did you order the cells from?
