Capacity testing the Gobelpower Battery. Can it deliver the promises? Charging/Discharging explained
HTML-код
- Опубликовано: 22 авг 2024
- In this video, we are going to capacity test the #Gopelpower Battery by doing a single cell capacity test as well as the full pack capacity test. As both of these results have been tested by Gobelpower and published on their website, it will be interesting to compare the results. Can it hold the promised numbers from the website?
I also explain the charge and discharge curve of the EVE LF 280K LiFePO4 battery we are testing and what voltages are important for both curves.
So, this is it: we have now seen the outside and inside of this battery, have tested the cells as well as the whole pack and also checked out the Pace BMS again. I must say, it is a wonderful battery. So, why should you spend another $60...?

My view is that equipment is improving. Coming out of manufacturing they are expecting to have a minimum of failure issues. And they though there customer service would have the ability to help. This is what they hope will happen.
Which brings me to the point that Andy, and others are pushing quality control to a much higher standard.
Last word “ Thanks Andy “ 😊
Thanks a lot!
Thanks Andy, you’re doing a fabulous job educating consumers AND manufacturers. 👍👍👍
Thanks, Dave. Trying my best to bring them all together. Gobel is the first to move in the right direction and shed some light in this mud of A-Grade, B-Grade and matched cells.
Finally a manufacturer has listened to the BMS master Andy 😅
... has listened to the community. Isn't that what we all want?😉
nice work, good to see the process again and again. thank you Andy
Yeah, this battery comes out really nice.
Another great experiment, Andy. I like these experiments.
Yeah, me too. Great learning and exploring. So happy I can share all this with you guys.
Ok. Your guitar playing skills never cease to amaze me Andy!
I practice a lot in my spare time. I have plenty of spare time 😄
Hi Andy!
And thank you again for this test.
These Gobelpower Battery are good, with the NEYYYYYY will be perfect.
But for me they are a bit expensive.
My example is a rack type battery 100A/16S- 51.2V all included and good quality costs between 1000 and 1200usd, so if you take 3 of these batteries, it costs around 3000 to 3600Usd, for the same capacity. But still cheaper! And 3 battery is 3 boxes, 3 BMS and all the accessories.
So sincerely they should make an effort on the price.
And we all know that the LFP 280 costs around 100usd/Pc so there are 1600usd of cells and After???
to reach the price of 4900Usd??
They are too expensive their battery is a shame.
But again thank you Andy for this test!
Well, you get this battery with 280Ah for US$2600. Plus shipping though
Hi andy,I saw on their site, but with cells that have a capacity of only 270Ah!? so definitely poor quality cells? the ones they don't use for the packs, much more expensive?! so certainly also, with different resistances and capacities, and there it is no longer the same? my opinion bought the cells directly from EVE and make the pack with their material, but I do not know if they sell without the cells?
But thank you Andy.
Intro music:- Dan Lebowitz "Wishful Thinking"
Yes, should be linked under each video.
My Gobelpower battery came with the same BMS settings as your BMS settings
Oh, right, that is great! So they actually deliver them like this now.
Thanks for sharing!
I can promise one thing, Volta Energy _will_ be listening to the community and definitely using input from people such as yourself Andy! It makes so much sense right? Hopefully more manufacturers will do the same, even if it is because of companies like Gobel Power that are leading the way and pressuring them to do so... However we get there as long as we get there! Within reason of course 😅
Beautiful day down here, Andy. Spring is almost here. Intro music love it Obe won.
As detailed as all your videos are, I still don't understand what a BMS does ... LOL, that was a joke. Comments help the channel even jokes. Thanks for all that you do. Thumbs up as usual.
The BMS is there for safety. It protects the RUclips creator from all harmful comments on their videos. Bad language, swearing or someone looking for a boyfriend, it will just switch off this user and ban him forever. You should never post a video without BMS these days!
😄
LOL. Always entertaining!!! @@OffGridGarageAustralia
It's a good day when the white board comes out
Hahaha, I should use it more often!
26:00 I believe you once had reviewed a BMS with a dry contact output that can be used to turn on/off an external active balancer.
Gobel / Pace should come out with such a feature.
This feature is on the request list for a future FW update. Would be great to give the customer the choice when to close the contact of the relay.
Great video. I did nod when promised to always use a BMS when charging.
Hahaha, great! 😄
great test, great battery, great result. 👍
Very impressive results Andy. Great Video!.
I'm very happy with this battery so far. More testing on the way...
I also note that the connectors on the front of the Gobel battery pack are well away from circuit breakers, menu buttons, BMS screen, etc so if you stack them vertically it looks easy to use long copper flat bars to bolt directly to the packs as busbars, negating the need for battery cables at all.
Very good point!
Great test Andy. This is a much neeeeeeeeded battery, looks great 👍
Andy, can you get one of the Gobel Power DIY batteries to examine for us? They're quite a bit less expensive than the A or B types. From reading the description on their site, it appears that the DIY version of the battery includes used cells, but it's not clear how much life might remain. It's also not clear about what kind of work is required to finish the DIY unit to get it operational. Can you look into that for us?
I would also be interested in that. Gobel Power wrote me the DIY version is already a finished battery pack. So I am wondering why is it than called DIY.
Unfortunately you can’t select the 4 A Bluetooth Balancer with the DIY Version…
I think IT is nearly the same as eel or seplos mason kit
I'll see if they can send me one. I would be interested in the DIY-Kit as well.
It is in fact the same battery just less matched cells. The NEEY is now an option for the DIY-Kit model as well. I guess they call it DIY because it needs a bit more maintenance. But with the NEEY included, I cannot see a problem at all.
I see the option to add the NEEEEEE for the DIY version as well
@@OffGridGarageAustralia Hi Andy, in this so called KIT are 270Ah Modules installed.....BUT, for the price there is no other seller...I would buy two of them for a little more money and the capacity is , i guess, factor 1.8
You'll want to check Windows power management settings on any PC you run for long periods. By default, Windows is set to be pretty conservative. I always disable USB selective suspend, and set everything to be always on (including monitor, I prefer to turn monitor off myself when desired instead of letting the PC do it). Annoying thing is you have to check often, because windows loves to update itself and revert these settings. Dell Optiplex (I generally only see them and deal with them in business/commercial environments) may also have its own power management settings in BIOS in addition to the usual Windows settings.

Hallo Andy, viele Grüße aus Hamburg. Ich schaue seit längerem Deine Videos und bin begeistert. Ich habe bereits für meinen Camper ein ordentliches Batteriepack selbst gebaut, aber jetzt ist die Solaranlage auf dem Dach und ich habe nicht mehr die Zeit für den "Kistenbau". Daher bin ich Deinem Rat gefolgt und bestelle gerade bei Gobel die DIY Variante. Danke für die informativen Videos und Liebe Grüße aus good old germany!
$2600 for the DIY kit is a great price since it has the cells also. I am thinking about ordering 1 or 2.
I thought the price of server LFPs had come down recently.
@@edc1569 not sure but they are already built just not matched cells. My cells are similar out of 64 10 cells spike faster.which means my 57.2 kw is now 56.2 kw. I paid for all $8900. This is a deal.
You can now order the NEEY active balancer with the Gobelpower DIY Kit battery so it will perfectly balance this pack.
I wish they would have sent me the DIY Kit. I may order one to check it out.

What BMS is in that battery?, I like all the inverters it supports, gives us great choices.
Thank you for all you do to bring this contect to us.
Thanks again
Fantastic video👍👍
Thank you 👍
Thanks Andy
oh nein, jetzt hab ich von den Ohrwurm vom Intro
Hahaha, slap hard on one side of the head, it will fall out the other side. Just do it hard enough😂
Not only a great Battery, but a great learning test for others! At this point, might it be worth doing some cost-benefit analysis of DIY systems compared to the new Tesla Powerwall 3?
The Tesla Powerwall is not something you can just buy and hook up to your house or system. It needs an installer and proper commissioning. Very hard to compare this to a 48V DIY battery, I guess.
@@OffGridGarageAustralia Indeed. I would think however that there are many people who might consider or even prefer going the DIY route over the Tesla Powerwall if they got more performance for less money and a bit of time.
Thanks Andy yet another very informative video....
P.S. I meant to ask you last month if your New concrete on your drive entrance has set properly without any tyre marks or footprints on it?
thank you for this information. and tests.
No problem!
Heya, nice battery test again but I keep it on diy so I can keep upgrading wen I have safed some money
Don't know if someone has mentioned this or not, but!... I know in the last video for these batteries, Andy mentioned surprise about the tested capacity of these cells. I'm thinking these are "failed" 304 AH cells. They didn't hold the respected amount to pass Q.C. testing and are rebranded as 280 AH instead. That would explain why they are found here as power bank cells instead of higher end uses. And also why they tested at around 300AH when the typical standard is just a few AH over the rated capacity. 🤔Just my thoughts on that. Still awesome for power holding uses and should last A LONG TIME!!!😁👍
I thought exactly the same.
They are probably just rebranded as 280Ah so they can still sell them
hhhmmmmm.... there is no K version of 304 Ah cells. 🤔
So if this theory is true, these are 3000 cycle cells labeled as 6000 cycle "K' version ?
These are definitely not 304. These are the new EVE280, you can tell because of the hexagon shaped battery post. The new EVE280 cells are really good and often test over 300AH.
It seems these are V3 of the LF280K with this hex shaped terminals and some said, they measure much higher...
Also who would do the re-labelling? EVE or Gobel? Both would not be right.
@@OffGridGarageAustralia
EVE lasers the B mark on them to avoid the reselling as a higher grade.
It seems that GobelPower is unwilling to allow the Neey Balancer in the DIY kit. :(
On the weekend it wasn't there, but now the option for the Neey Balancer is available
They said, they are considering the option for the DIY-Kit. I cannot see why they wouldn't give this option.
Yes, confirmed, it's there now!
Andy, don't most battery manufacturers rate Ah by taking the measured Wh result and dividing by the nominal voltage? In this case, 964.88/3.2=301.525Ah which is a bit closer to their published test results on cell 142.
No, no no no, that would be so wrong. I know Sun Fun Kits is doing this but it's not correct. Voltage is not constant, so how can you just use 3.2V and not 3.25V. Or 3.23V. Or 3.21V???
Wh is energy, Ah is capacity. both very different!
Ah is the only true way to measure the capacity as it eliminates the voltage altogether and makes the result comparable.
I like the longer intro.... 😊
Aha, was that you who left the comment recently 😄
@@OffGridGarageAustralia
No, it wasn't me. But I agree. I like the music, it's very relaxing.
😊
Ευχαριστούμε!
Thanks a lot Mr Multiplex!
More videos Andy!
@@PlexMulti coming
Hi thanks for the video - which software areyou using there to check the settings of the BMS? Thanks!
I HAVE THE SAME QUESTION - because the link you have in the (Gobel cloud) does not have the software you are using. I have also bought 16 of them (B type) from Govel and the measurements I made are almost 300ah (same ZKE tester 40A). Thank you for Greece :)
I have now linked the software on my website under the Gobelpower and Pace BMS section:
off-grid-garage.com/battery-management-systems-bms/
@@OffGridGarageAustralia Great, thanks a lot! Does it also work with other BMSes, e.g. Seplos? Does Seplos provide a desktop app on their own?
In regards to the active balancing doesnt the function to start balancing in the BMS turn off the balancer if it is below 3.45V. If not then the Neeeeeeeeeeeeeeeeeeeeeeeeeeeeeey is the way to go as you have stated.
How Andy and the community, I have 3 server rack batteries, 48 volt, 300ah.
They are similar to the Gobel, from China but don't have the circuit breaker.
I have noticed with my solis inverter that i was getting a major drift in the cells when set up for pylon lv, i have changed back to user defined, I'm still hitting 3.6 volts on one of the cells and this causes an over voltage and stops the charge, which is fine as a safety method, i don't have an active balancer installed as of yet. I monitored the batteries when charging to 100%, but there is only a small window when the balancing commences, The charge rate lowers the closer it gets to 100% but not enough time to balance the cells.
My voltage charge rate is set to 56 volts, i have a floating voltage of 55 volts for 5 minutes at 3 amps, and a battery over protection voltage of 55.5.
While charging the battery to 100% yesterday i noticed the voltage got to 55.2 and one of the cells got to 3.6 volts and stopped the charge.
Can you guys let me know if these voltages are correct?
Or am i doing something wrong,
If i increased the charge voltage will that make a difference?
Also Andy, I noticed you changed the cell under volt protection from 2.7 to 2.5 volts, my question is, do you have to change the pack under voltage also, in the settings of your BMS, the under voltage protection for the pack is 40 volts?
My BMS is set to 2.5 volts under volt protection for the cells, you said in a previous video to stop discharging at 3 volts per cell, should this be changed back after your test in the BMS settings?
Thanks for your message and questions.
First of all, it seems your charging numbers are not correct. Your charge voltage (56V) is set higher than the overvoltage protection (55.2). That makes no sense.
Set the OVP to 58.4V and forget about it. Set the charge voltage to 55.2V and see if still one cell peaks. You haven't told us what battery and BMS you have so not sure what kind of balancer it has.
At the lower end, my 2.5V settings are only required for my testing. In the real world, there is basically no capacity left under 3.0V, so leave yours siting on 2.7V, totally fine. The pack under voltage protection can be 2.7V x 16 or I would set it to 44V or 45V just in case. The inverter should shut down at 48V, so before reaching that voltage.
My 3 batteries parameters where all off.
I changed them all to suit each other.
Hopefully this will solve the error of the over voltage alarm
Thanks!
Thank you very much Karl. Very generous of you. I will drink a SPAT for your health tonight! Cheers
Does the gobel power BMS perform firmware updates like the SEPLOS did ?
I think Gobel used the PACE BMS but I am not sure if that supports firmware updates too cause SEPLOS had been the only one in the past.
EVE LF280 K Spec sheet has a full description of the procedure and you would need a test room offering 25°C all the time cause that is the standard procedure for comparisons what you should get out of the cell.
Yes, it supports FW updates like all these style BMSes do.
I have done one for the Jakiper Battery a while back which uses the exact same Pace BMS.
Yeah, I don't bother with these tests. Gobel takes the results to match the cells and it seems to work quite well.
Actually, I will have such a room soon'ish but such testing is not what I'm particular interested in.
Andy, I had to correct my latest new jk bms battery voltage by 0.2 volts. Both meter and victron solar charger gave same voltage. Jk bms was different. How is the gobel? Spot on?
I would not be worried about 200mV difference. The JK as well as most other BMS can be calibrated. The PACE BMS seems to be accurate as far as I can tell but I don't really know as I have not tested and BMS for accuracy yet.

Ouch! $720 Sea freight shipping (to the US) + 4.4% payment fee!! ($135) - My total would be $3195.87 shipped to me with the discount! I was hoping for like $300-$350 shipping. Assuming the nominal 280Ah.. That would be ~$223/kWh! Now I might go back to the Full DIY route! :-( Really $700 to ship by sea??
I checked shipping to Canada and it was $1300 CAD lol..
Have you got in contact with Gobel to get a quote for shipping? I don't think their calculator works correctly for shipping to some locations.
@@OffGridGarageAustralia I did send them a message.. I quoted just the batteries they have for sale and it was ~$320 for shipping. Which seems more in line with what it should be. Maybe I'll just get the batteries from them and a case from like EEL or something...
@@jbuszkie Andy is ignoring those statements because he will get less money from gobelpower if he says something negative! A lot of people told him that they tried to order and got this overpriced quotations for shipping and packing - instead of checking it he is attacking his audience or saying nonesense. I will not longer watch this advertisement channel... Money is everything now?
I heard back from Gobel.. And they reduced my shipping to $660... Still too much in my opinion! lol
On the DIY version you can not select Neey balancer
You can now...
hey Andy,whats setting pack full voltage in parameter do?
in yours,its set to 55.2v,in my bms setting its set to 57.6v
That is the maximum charge voltage being reported to your inverter. I charge my battery to 55.V only.
I have a slightly offtopic question. A friend of mine who recently moved to Germany has a quote from the power company for connecting the power. They are asking more than €2000 to reconnect it. It was turned off years ago before he bought the house.
Everything looks fine with nice hager box, a 3 phase meter installed and some kWh on it. Is this a normal amount in that situation?
For this kind of money and the yearly cost I am thinking of helping him go offgrid as he has very little to power. But my German is not good, it is far away for me to drive, and I don't know what is allowed.
Is there anyone who can tell me why this is so expensive or knows how to get them to lower the amount if it is incorrect? Maybe it's me, but reconnecting power should be not much more than putting in some new fuses.
Would this be something you would recommend over a Tesla Powerwall 3,which I've just read that it will not support 3 phase AC homes.
noticed the bms updated remaining to full when charging was stopped at 57v.... so you would need to update full so a false capacity is not used.
Yes, this happens when the SOC goes to 100% as the charge voltage is reached. The full capacity will actually update automatically every time you fully charge.
@@OffGridGarageAustralia Right my point was if you set the charge V low like 13.8 like you had said in other videos then the capacity is incorrect for the full charge state?
@@markwright196 If you absorb for an hour or so, the soc will be pretty accurate, even at this low voltage.
The EVE 280k cells are really good. The cells are well matched...good work gooble power!
After Absorbing, you probably charged to 99% at 3.45V 👍
The low temperature charging release sits on 15°C...WTF???
It seems like the Pace is only a "charge balance" BMS
It is disconnecting after reset to 100%...not good at all Andy. Please don't put your Integrity on the line, ok?
Yes, it seems like they modified the settings especially for you. I just got their Pace BMS and the high voltage disconnect was at 3.70V.
Yeah, 3.45V and absorption for 1h give us 99.4%SOC as we tested in the past. The aspect here is to keep the voltage as low as possible but still reach a full charge.
Yes, the PACE BMS is only balancing while charging except you hit a OVP (cell or pack), the it will keep balancing even the charge MOSFETs have been turned off. See the BMS Comparison Spreadsheet 😉
The 12% discount doesnt work. I used the link from your website.
I'm running my tester software from a computer with Windows LTSC, never failed me.
Im looking at this compared to the seplos mason kit in your offgrid garage opinion whats better ? Im buying two units hoping for 30kw at 48 volt ?
The Gobelpower is not a real DIY Kit. It comes with all the batteries and is ready built.
The Mason is a true DIY Kit where you need to buy the batteries separately and need to put everything together.
Yes, if you buy two 280Ah, it will give you 2x ~14kWh. 2x 304Ah will reach 15kWh each.
BMS Tools version 3.3 is available fyi.
Thanks, I'll have a look...
Andy, what would you recommend for an 8S system for a 24v campervan? Could be a bit smaller capacity (150Ah+) but would like to have proper BMS & balancing (50A+ charge capacity). I would consider DIY, as I do have some solar / LV experience. Do these BMS & balancer units work with lower cell counts?
You can get the Seplos Mason for 24V as well but it has the same dimensions. They just use two 280Ah cells in parallel and make a 2p8s battery but in the same case. That might be a bit too large and heave for a camper.
Alternatively, have a look at the Sun Fun Kits 24V system. Use OGGA at checkout for 6% off!

@@OffGridGarageAustralia Thanks Andy - yes the Seplos Mason would be too big.
Do you know if the JK-200 BMS/balancer in the Sun Fun kit is any good? Ideally I'd like to be able to optimize parameters.
Andy, is it possible to look inside on Active balancer, if it is possible to solder a on/off switch?
They come with a solder pad already and you can just unsolder that and have wires connected to the RUN pads.
I've shown this here at the 18min mark:
ruclips.net/video/ZplbAAqnrjo/видео.html
Grüezi and thank you, Andy🎉🎉🎉 I have two of those batteries already. Unfortunately without the Neeeeeeeeeeeeeey - can I just buy one and replace the Gobel (Heltec) balancer?
Hello! Yes, absolutely, you can replace the Heltec with a NEEY.
I'll do a test with the active balancer turned on all the time and only working above 3.45V right now. Result is coming soon, maybe wait for that before you start...
Thank you for your reply, Andy, looking forward to the new tests✌️
I run a total 12V small shack system and curious. Would one of these systems be able to power a 12V system and can I use my Victron MultiPlus II 3000Va charge it somehow?
You mean the Gobelpower battery? It's a 48V battery, so not compatible with any of your equipment may you already have. The Multiplus II you have has a 12V input only, so won't work with the 48V system.
I need your help in understanding my pylontech 48v 100ah ithium ion phosphate battery, it has been added to my hybrid 5kw solar inverter, the problem is the battery will gradually reduce the voltage from 49.9v and it reducea slowly and abruptly shutdown and says o% soc. Please help me to fix this issue and get the battery maintains the 49.9v at every charge please.
Thanks
Thank you very much!

Amazing ❤
Is it possible to run both balancers, the one of bms and a neey at the same time? Or is it better to turn the bms balancer off?
They can run at the same time, no problem. You can have as many balancers connected as you like. They all work together and balance the battery.
My EBC sometimes cuts out during discharge/charge cycle as well. This happened twice during 32 tests. I suppose it is some bug in the software that needs sorting.
Never had this issue before. After fixing this stuck Win update it seems to work again.
You tested all your 32 cells?
I tested three lots of 32 cells! My first supplier was below spec (about 290Ah instead of quoted 310Ahr average) so having tested a few I did them all and then complained through Alibaba to try to get a small refund equating to the difference in price with the 280Ahr cells but got nowhere. This led me to check all cells I have subsequently bought. In the later two orders I used recommended retailers and found that the actual and quoted capacities matched fairly well but not as good as yours. As each pack was 16S2P measuring all the capacities help me pair up the cells to balance out the combined capacities.
Andy when are you going to wire an active balancer into your Tesla pack?
I have never seen any larger deviation than 20mV in the Tesla. Their balancer is pretty good. It's an open patent and you can google it...
If only i had expoqable income to get like 6-8 of these, but i'll have to make do with what i have... They look clean though.

@@Lana_Warwick , they offered to ship for $250 - and that is completely reasonable. But I need to deal with customs by myself.
@@MrJanulis $250 is ok, the rest unknowns concerns me also.
Andy needs to import container full, become Oceanic supplier, with his video tutorial showing us "what to do", after huge man drops it from van.
I'm wondering if the resistance in the battery leads are being calculated in your testers results. My leads get warm when discharging at 40 amps...That heat loss may not be being compensated for by the tester. Just a thought.
The leads can be a 100m long and it would not make any difference. It would still test the battery with 40A. The ZKE tester has 2 extra cables to measure the voltage accurately. That is all it matters.
@@OffGridGarageAustralia The "extra leads" are not clamped onto the same spot...the studs or the contact platform may or may not have the same resistance which may make a difference over time....just wondering.... :)
How many kw is that battery
100Ah = 5kw
15 kwh
👍👍👍
what BMS is actually in this battery? I need to buy 5 or my 70+KW project. Andy, I assume we can purchase this BMS as you have previously tested it..
It is the Pace BMS that Andy tested recently in the bigger Jakiper battery .
Yes, this BMS is great. I've tested the Pace BMS here:
ruclips.net/video/Wqvj4R--uNE/видео.html
Andy, the basic model (even with 4A neeeeey balancer) brings according to gobel power website a voltage range of 49V - 54.5V. Is this correct ? What is your opinion about the basic model? Because I think you tested the premium model with eve cells... maybe gobel sent you a better version than the real basic model reflects...
I would not buy anything else than the basic version with the 4A NEEY balancer. Once top balanced, it will charge to whatever voltage you want, up to 58.4V, no problem.
It is a bit confusing why they say it's not charging higher than 54.5V. They test all batteries unbalanced to make the batteries comparable. The basic model has just cells which are not as tight selected as cells for the other models. But the balancer will fix that, 100%.
@@OffGridGarageAustralia Shit, I read your answer to late and payed now already an upgrade fee of 430$ to get a standard version. However, with this I think (hope) I get 5 years Limited Warranty also to the BMS, 1.2kWh more capacity and 10kW output power instead of 7.7kW. Was this worth the money?
Danke!
Thanks a lot Gustav! Appreciate your generous support!
Hi, vielen dank für deine tollen Videos , ich habe eine frage was für ein BMS kannst du empfehlen für eine 16S LiFePo4 ?

Hi, thank you very much for your great videos, I have a question, what kind of BMS can you recommend for a 16S LiFePo4?
greeting
I looked at their website after your last video. Their prices are very high.
Thanks for saving me the time
Compared to what ? Most of the ones you see like this are only 100 AH . These are 280 AH .
Do the math on kW/h price. It is 166 dollars per kW/h. That is very low compared to almost anything worth buying actually...
An EG4 with 100ah at 48V is close to 250 dollars per kW/h
That is like comparing the price of a 100 gallons tank with a 300 gallons tank prices... Not comparable.... At all.
These might be the cheapest kW/h for this quality... It is a great deal.
A 100ah 12V battery with a lower quality overall is 1,280kw, and their cheapest cost 280/300 Bucks...
@@ricardomarcelino8388, have you checked shipping price? £2106 for batteries BUT £4627 for shipping!!!!!
@mrm7309 The price is probably lower than a DIY battery you build yourself.
Not sure what you compare the prices to?
What is a good, cheapish 30+ amp AC powered battery charger? I need one for a portable hybrid power project I'm working on. Paying over $200 for one kills the economic viability of it for me.
Hi Andy 299Ah is very high for a 280Ah or a bit low for 305Ah. Does Gobel sell these battery's with a fixed price or is the price depending on the capacity? Or... did Gobel power just build a perfect battery for your channel? While talking with Gobel about a month ago, they confirmed knowing your channel. So this battery might be a special build.
Others here have commented that these are the new V3 of the LF280K and apparently EVE has underrated these cells to overcome any complaints about low capacities. Capacity tests with these have confirmed my results and some had even higher results with over 300Ah.
These are genuine EVE LF280K cells with a 'B' on the QR code.
How many kWh of batteries do you have now in total?
Only 44kWh in the battery shelf. All the other ones are not connected and only for testing purposes at the moment. I'm not sure what will end up in the production system yet.
@@OffGridGarageAustralia I know they are only for testing, but curious just how many kWh in total (all48v battery packs), got to be getting on for 100kWh
Hi Andy. When doing a charge and discharge (and partial recharge) test, I tend to do the initial charge at 3.55V at 40A with cutoff at 39A, before charging at 3.65V at 40A and cutoff at 1A.
I have no idea if this improves capacity, stresses the cell less, or just takes longer 🤔😜
It will have no effect on the cells as long as you don't exceed the 3.65V. But it makes sense to do so to give the balancer time to sort out your cells.
@@OffGridGarageAustralia I was talking about testing cells individually with the ZKETech tester, sorry I wasn't clear 🤪
How many miles did you gain on the Tesla from the 15 kW battery
der einspieler war recht beklemmend :)
🦦 we love your intros 🐬
Great, I'll make more!
How much range did you get into the Tesla from the 15kw?
My Model Y will get around 105km out of 15kW of charge.
I should have shown that. It was 132km!
@@OffGridGarageAustralia Thanks alot... We in South Africa don't have the joys of many EV options so it's always interesting...
Measurement uncertainty will never give you the same battery capacity as someone eleses measurent.
$7 for 15kwh seems like a lot. You can do a 4s 12v off the shelf lifepo for $4800 for 15kwh these days.
I agree , I can get an EVE 280ah 48v battery with bms for $5300 in Australia just need a shelf or box to put it in
The battery is US$2600 for the cells, case, BMS, and all accessories, ready built. Cheaper than something you build yourself, I guess?
It's "without further ado"
he knows... He does it on purpose now!
100% 'without further to do'. If you listen carefully, it is 'to do'!
For the love of God, Andy, please, PLEASE change that jingle/intro "music." Even Cat Stevens is tired of it now!!! Lots of us HATE it now.
How to get the Upgrade to a neeeeey Balancer? I don't find the Option on the Page
It is not available for the DIY battery. :(
It is now available for the DIY-Kit model as well. They just changed it.
Don't know what exactly the crash of the software looks like, maybe for security reasons? The clamps on the battery terminals are not optimal, high voltage drop possibly? Better tighten with cable rings?
The tester itself was still running, ok.
I've never had a problem. And even if you switch off the PC software the ZKETech continues the current program until the end (e.g. full charge). But his seemed to stop midway through a program, indicating a problem with the charger (although I don't get how that would stop the software).
But it's a pretty old PC, so I guess there are plenty of potential causes.
The tester has no voltage drop as such. That's what the small croc clamps are for. They measure the voltage accurately no matter what. The big crocs are just for sucking the 40A, no matter how good or bad this connection is.
So any discussion about voltage drop, too small cables or sub-optimal clamps with this tester, is totally unnecessary.
It's not the PC, running 100% perfect without issues. The problem was a stuck Win10 update. I removed it and since then, the software is working again. All fixed!
Yes, the tester works off it's task even without PC but not if you program a sequence like I did. It then stops at the end of the task it was doing when the PC disconnected.
@@OffGridGarageAustralia Yay!
Truly a great system, but a bit too big. We want more, or actually less. More or less.
It is huge and very heavy. Nothing you want in a caravan, RV or lift upstairs anywhere.
🐸🐸🐸
Sadly, Gobel Power is completely useless to me in Switzerland. Battery Premium 3500$. Shipping 4600$. Lol. Goodbye.
Yo
🥇
No EU availability. VAT and Taxes makes it a no deal. I can get a same capacity for less.
lol gobels b grade cells are better than some other vendors "certified" cells
did they know who they were sending this battery to?
Yes, Gobel knows.
The new EVE 208 with the hexagon post often test over 300Ah if not stamped with a B.
Nice Trolley. LMAO
Isn't that what it is for?😉
