- Discover Battery AES is built rock-solid! There is a thick steel case and multiple UL listings. Let's test it!
Lithium Iron Phosphate cells (LiFePO4) are some of the safest on the market. This, combined with an over-sized BMS, makes for a great home energy battery. This can be used in residential solar and mobile applications such as RV's, Van, and tiny houses.
Discover Battery model: 42-48-6650

Impressive product.
Website doesn't list prices.
Contact sales for info is always a sign of overpriced stuff.
Yea whats with the secrecy? Wants you on the mailing list.
The manufacturer doesn't sell direct to consumers. You have to buy through a solar distributor.
@@DavidPozEnergy Ok, it wholesales to distributors.
SOLARIS sells it for $9,209, now on sale for $7,365
@@iteerrex8166 Ecodirect $5725 plus shipping...lol
I really appreciate the attention to detail and the thorough approach. Easy to consume, not dry, and zero fluff. Bravo
Great video and awesome review, David! At these current levels I am glad to see you use your IR camera to look for hotspots. But you might consider investing in a good milliOhm meter to make sure that your connections are tight and wire resistance is balanced.
Can we take a minute and appreciate how robust that XW inverter is 😮.
big time, 130 amps at 48 volts aint no joke
I always love the instruction booklet that tells you just how to open the box after you have the box opened... God to love it...
Love how much work you put into your videos thanks man..
Another great review David, we appreciate all the work you put into your videos for you viewers !!.
Thank you.
Great review!!! I loved every test passed!! Good job bro!
Extremely well done. You never disappoint. Thank you.
I just finished setting up 30Kwh with a BMS for $4,300 (this price already includes Shipping costs). Not only that, but the 32 cells were brand new, A-grade CATL 280Ah cells - the best of the best, and shipped by an American company, located in America. Amazing deal!
Sounds pretty awesome. What batteries are you talking about and where did you get them?
Lots of unused CATL modules dropping on the market lately as assembled packs, damaged cars or trucks, vehicle totalled.
Batteries are from Battery HookUp. They were assembled for a project that never made it to production, so battery hookup has stacks of these 280Ah CATL cells which have never been used (they dissemble the packs, so they do have Epoxy on them, but that is not a big deal). It's a fantastic deal for brand new , grade A, CATL cells.
Thanks, David for your time again. The batteries are good and hopefully, the prices as usual will come down and be affordable for all.
Excellent review and commentary. I have one XW6048 and 3 Discover 7.4 running a small farm house. It is a golden combo and I wish I had more. Batteries are built like a tank and the inverter can handle anything you give it.
You get to have all the fun!!!!!!! Great content always. Now I want some (more) batteries! That packing, wow, they care.
Cool test setup. Thanks for the vid.
That overload capability is great. It means that you could load-shed a big load (like a shower) by measuring the current actually being drawn from the inverter - you have enough time for a contactor to operate to drop the shower if someone starts a more critical load.
Yeah, you even have time to warn the person showering that their shower will go cold in 30 seconds :)
You take apart most batteries. It would have been interesting to see the internal construction and vibration considerations as you were touting the external features. Thanks. Love the channel and I think you are doing a great job for your family. Happy Fathers Day
Awesome video! Thanks for all of your hard work.
David this was another super informative video from you as always. I being older have a problem with the metric system if you know what I mean lol. Help us old folk out by giving both to us please. As for cost it is expensive, however, you pay for what you get in quality by the looks of it. Have a super blessed week.
I have never wanted a battery more than I want one of these. Wow, that build quality is amazing.
That is the definition of mil spec.
The use of splitters really lets them down. Otherwise looks great!!
Impressive for sure I sure enjoy true plug and play as we know it is not common. I like that second panic look at the battery when attaching the wire that is one we all need to do every time to make sure our colour code is correct lol. Cheers on another great video.
Thanks
That Battery is a good compliment to the Schneider inverter which also is capable of exceeding its published specs.
Yes, I agree. They both impressed me in testing.
There’s nothing more permanent than a temporary installation. Maybe not, but the wall mounted configuration I opine, is much cleaner and stable especially for anyone even close to a seismic zone. Question: Since these feed an inverter with at least ~ 120V AC inverter, is there any need for an equipment bonding jumper, so all the metal cases and enclosures remain at the same potential in case of a fault; thus, providing a path back to the source? Even ~ 54 Volts DC in those high Ampere discharge rates I imagine could be shockingly dangerous 😂. I don’t have much experience with commingled systems, and there may be very good reasons for keeping them isolated.
Well done video. Testing and setup well performed and well explained.
Excellent review. A small fortune but incredible battery, very impressive David, Many thanks.
Thanks so much. Lots of awesome info and point of view.
Impressive integration between the XW Inverter and Discovery AES Batteries!
I'm really enjoying your work, David. Of those who specialize in this sort of technology, you seem so possess a kind of humility and sincerity that most of the others lack. Your presentations are explicit and straight-forward and easily understood by the ADD-Afflicted amongst your audience.
Thank you, I appreciate that.
Looks like a great battery...
Can't stand sites that don't show the product prices...
He told us the price - $600 per kwh is about $4500 per unit
another great review!
Hello DTG, you're the one I always go to when I want to be sure of anything in the solar world. Many people I know only swear by Solark 15K over Schneider XW Pro. You have the final word. Thx
Bulky set. Works great. Love that Schneider software.
Never heard about this company before, but they look amazing! Great review.
Having now looked into the company, I see that they are in the process of releasing a server rack battery called Element. Hopefully they will send you one for review 🙏.
Hi David, I wanted to thank you for your efforts in making this great content. I am very envious because I live on the north side of a steep mountain on a completely wooded lot. There is no solar panel sized area of my property that gets direct sun more than 5 hours per day, even in peak summer. So solar is out for me. Also Tomatoes ;) Still lots of fun to watch you do it.
Your welcome. Thanks for recognizing the huge effort it takes to make these videos. I'd love to live on a mountain side, so I'm envious of that. Perhaps a wind turbine could work for your site?
Wow, I live in a cabin surrounded by SWAMP. 😂
Since you live high up, you might want to look into electrostatic motors. (Note: this can give 24/7 low levels of power all day!)
For the higher you are up the more power you can get! (With enough wires, you might be able to farm 1000 Watts or more! All due to height!)
en.wikipedia.org/wiki/Electrostatic_motor
@@marlonlacert8133doesn't the atmospherics static, get pushed up from the mountain?
I'd probably say yes and no. Yes because of the ground. And no because of wind.
quite solid specifications, let alone the fact that actually overcome the expectations (over 200 amps lasts a minute which is wow)
for me 1C charging is a great thing even though I wouldn't use it, a 0.75C charge and a maximum capacity of 85% should keep it safe and healthy along the entire lifetime
read the datasheet before assuming the cells can handle 1C charging.
Really good man! Thank you!
Great comprehensive video
Plus rivets where you aren’t in studs would be a good option
Or could have put mounting plates on before putting plywood up with nut serts on back side or through bolt with large washer, small recess optional on mounting board or wall
No worries about battery position relative to stud positions as long as you secure your plywood to studs correctly
I work on RVs and have to put mounting plates in and secure mounting plates
Dry fit with cardboard the size of your batteries and make sure you have room for wiring
wow! I was suitably impressed.
Discover has (for years) had a video out dunking on SimpliPHI showing the robust internal construction of AES build versus that of the less-capable SimpliPHI. All-said, I have a stack of nine SimpliPHI 3.5/48's because the Discover AES was not on the market back when I researched and purchased... There is an extreme voltage sag from SimpliPHI modules when pulling full load on the system at less-than 40%-30% SoC. Unfortunately it is time now to expand the inverter capacity (and so too the storage capacity) and I have to make a decision about whether to buy more SimpliPHI modules to match the existing open-loop system design, or re-invest in a new battery array to gain closed-loop operation. It's exciting anyhow that home energy storage battery technology has progressed so much in the time since just before Discover AES arrived to market - I wonder if Discover has any plans to update with greater energy density for the AES platform?
You don't have to do one or the other. For example, if your new inverter system will require, say, 250A, then you could buy 2 Discover batteries (rated for 260A continuous). They can be paralleled with your existing SimpliPHi bank at a central bus bar. The closed-loop communications of the Discover will talk to the inverter. The SimpliPHi still will be open-loop, but expand the capacity. I'm wiring this up now with my existing EG4 battery. Same concept. The Discover battery does the talking.
Man those Reliable brand inverters are awesome. Just sold one I used almost daily since 2018
Looks like straight out of a battle ship tough (just toured the USS Missouri). Even painted the right color. I will have to go for a lesser one due to cost but these are beasts. Very nice.
Thanks for sharing the great testing as always! Do you have any experience with Epoch batteries? (I think they’re made or at least based, in Atlanta, GA)
This was by far the best review of a battery. Battery seems to be built to military specs almost
Milspec means bare minimum.. Lowest bidder got the contract.
@@jeffery19677true. Some of the specs can be impressive though! I've seen both ends of that lowest bidder spectrum
some people might think these are to expensive @ close to $5k each(about $150 for shipping), but for what you get its prob a better deal than others. This is the first Ive seen these, they seem rock solid, safer than Lipo, and should last a long time. Only thing I'd like to see is maybe a small screen built into the battery so you can check there current conditions real quick.
Looks like in the summer they will introduce ELEMENT ESS Battery basically looks like SOK or EG4 batteries. Just waiting for the UL certification. Looks like they will have a rack for up to 6 batteries and also have outside racks for these. Brief description manufactured with the highest-grade cobalt-free LiFePO4 cells.
OMG ! It has been a while since I’ve watched the channel and I was surprised by the beard and hair! 😮. You are now a match to my 19-yr old son, except he is 6’7” tall and has red hair and beard. But otherwise, you’re a match. 😂. Love your channel and wish I had your skills. My son is mechanically inclined and thinks RUclips is the new classroom. I will turn him on to your channel because your videos are well developed and your explanations outstanding. Please keep posting! 😊
i took some time to look at these in quick detail. My thoughts are firstly that i don't like that they are have passive bms in the box. Wondering what your thoughts were on their inside control as well or rather wondered if you checked on it. Cheers..
I hope you continue to improve and teach what you're learning in your path to net zero. I loved the pace, information and test you're providing. Not too technical, not too shabby.
Subscribed.
pace? i had to watch it at X1.5 speed because he talks soo slow🤣
Well I'll tell ya what you need to get. Well it depends on the size of your house and how much current you are using or area of country. It all plays a part. For starting out you need around 20k or more in inverter power. I have 26k. Need around 200,000 watt hours of Lithium. And around 30KW of solar panels. Reason being is when it's winter and cloudy for days on end you panels produce next to nothing. You need a big battery bank. Also a genny would be nice.
Hi David. Absolutely love your channel and have to ask your opinion on supercapacitors. I have been experimenting with one nesscap 16v 583 farad capacitor. For solar storage for a home as long as I have enough capacitors (yes I know they only hold a fraction of what a chemical battery does) in a large room. They theoretically last forever and you can charge them at any rate just have to have a high voltage limit.
Am I missing something? Would love your opinion or if you have already done a video tell me which one lol thanks from Canada
The high current capacity of these batteries is pretty amazing. I'd like to see them offer a high voltage version, like 400 volts. That way it would work with the Dcbel Energy r16 DC power manager, which wants 400 volts DC nominal.
You want people to have access to 400V DC ,,, I guess you are a supporter of reducing the worlds population :)
Seriously impressive performance.
Could you do a video on the anti islanding feature pls i have issues setting it up
When you mention the 3amp difference in charging between batteries, would that be partially due to the batteries having different SoC?
Love your content David; Side note I always get a kick out of your thumbnail subscriber photo vs what you look like now. Looks like a guy with just hopped on Grateful train 😂
Hmm, good point. I should probably update the photo.
Great Review
Where the positive and negative terminals are, I'm wondering if there is a non-electrically conductive, but thermally conductive material they could use, to keep those points cooler. Seems like an opportunity where the big red and black pads are.
Most important elephant in the room on this fathers day is BRAKE THE HABIT of TOUCHING TERMINALS some day you might get bit and it will kill you it scares the poop out of me when I see someone talking to a camera while touching the terminals. I have 39 years experience as a electronics and design engineer. It starts out with "it's only 12 volts" or "it's only 24 volts" then "it's only 54 volts" . Try going to a funeral with a friend laying in a casket face reconstructed due to part of it blown off from touching a terminal. And the crushing grief from his fiance and family dealing with " it's only ? volts"
do u know anything about the release of the new sodium ion batteries, and when they may be available to purchase in the uk?
Hello DTG, I remember asking you a while back, if you ever tested Discover AES, you said no, I'm glad, you finally got your hands on them
Yeah, it was fun to try them out.
@@DavidPozEnergy if you ever wanted to set the batteries up a Schneider or whatever system all on 1 board, I can purchase 5 to 10 of them from you and put them in my homes. 110 and 220 outlets with a honda generator if need be. All I'll do is purchase the batteries too, from you and set them up. Maximum 20 to 40 panels (230 watts or 600 watts) 2 discover batteries per system
Nice work, Dave. I think I need 3 of them for good luck. Not to happy with growatt. David your rocking that hair and beard, mate.
Hello DTG, I got news for you, we tried the newest EG4 18K-PV 48 V and it's awesome. The easiest installation ever. This beast with 4 Discover AES 48V (6650 AH) is all, I'll ever need. Thx Dave, I hope you get your hands on one and try it.
I'm glad to hear it. Are you posting about your installation anywhere?
@@DavidPozEnergy No DTG, I'm too shy to do so. You will love this beast, you don't even need a combiner box with this hybrid system. And it's only $5,999 compared to Solark 15K, $8,000+
I agree that the EG4 version is a better bang for the buck compared with Sol-Ark. If you are in New England maybe we can get together?
@@DavidPozEnergy That would've been a dream come true. You're my hero Dave the Great!. You've so many tools, I wonder if you knew how many. I live in NJ and collect used panels and batteries for people in Africa where millions of people can only afford one 50 watt solar panel or one 100 watt panel for an entire family. So having 2 (100 watt panels) is being ahead of many. My biggest dream is to be able to set up a website that will collect used solar equipments for them. ( 99.99 of all solar batteries in West Africa are 12 volt
They usually get the used ones from Europe instead of the new ones). Electricity over there like in Europe is 220 Volt. Thx Dave the great for all your efforts. Wishing and your family the best.
From the other comments here, it sounds like that 7.4 kWh battery costs either $4600 or $7300.
Where I live (NC), 7.4 kWh of electricity is worth about 80¢ (retail price). A good LiFePO4 battery should be good for about 5000 charge/discharge cycles. So, over its life, that battery might store a grand total of about $4000 worth of electricity.
So the battery costs a little more than the retail value of the electricity that it can store. That's actually pretty good for batteries.
Thank you for reading through some of the comments.
I agree, it's a fair price, but not a bargain. But, this battery has the UL listing which some of the less expensive options don't.
The Discover Litium BLue DLB-GC12-12V 200Ah batts looks cool too.
You did awesome job explaining the step by step setup, thank you again for another outstanding video. The company that sells this battery however have no listed price, instead they want people to contact them for pricing, that's very shady. For that reason I simply will not have appetite for their product.
They don't sell direct to consumers, only wholesale pricing. There are several distributors in the US that sell these and I've seen pricing about $4500. But, it will vary quite a bit from one supplier to the next.
where did you get that Ah meter? I need one of those to test my batteries.
Impressive battery!
That crate reminds me of the portal puzzle game old school cube!
The crate is a lie
Why was the little timer you added on the bottom @13:30 ish, running so slow? It would show 1 second change every 2 seconds? The video timer showed 13:24 when you started the test and 15:22 when the test ended. Meaning the test ran right at 2 minutes. The timer you had on the bottom of the screen only ran 58 seconds.
Wow! Nice Device!
Wish I could afford such a setup, for my 3-D printer..
Tired of power outages glitching my prints.. 😂
Excellent !
So they cost about $4200.00 each? I went to their website. Looks like a third grader or a scam artist built it. One of those sites selling you a book for $9.95, but if you pay $29.95, you get three books and 14 OTHER "bonus" books..
Anybody who won't tell you a price on their website doesn't get my money. If I have to call and talk to a salesman, they are overpriced.
Love the video and how you explain everything.
Thanks!
Great video ,testing was brillant easiely explained....question what make is the meter you use to display the voltage and all the other setting, where can i buy one from?
I'm using the Victron smart shunt. The shunt itself doesn't have a display, so I have it connected using bluetooth to an old cell phone.

That's not a "disclaimer". It's a disclosure.
Oh, is it? I'm not a lawyer, LOL. My intention is to have full transparency. Thanks for letting me know. I'll correct the description.
25:31. There is a major issue with your lag bolts going into the plywood, in that they have a shoulder section without threads that looks to be at least 1/2 of an inch long, and may be closer to 3/4 of an inch. The result is that the bolts are relying mostly on friction between the smooth bolt and the plywood instead of having the threads engaged with the plywood along the entire length of the bolts. They will likely hold for a period of time, but will likely eventually work themselves loose. Far better to use either more #10 or #12 screws, or the specified #14 (1/4 inch), as long as they all have threads along the entire length of the screw body. This is a somewhat common mistake that I have seen equipment installers make when bolting to thinner substrates such as plywood.
2/0 is plenty big for the paralleling jumpers, since they only carry 1/2 the load, and a 2/0 75º conductor in free air will carry 265 amps, enough for a 12 kW inverter at 48 volts.
Excellent review David. Reminds me of Snap-On versus Harbor Freight. Some very nice batteries. That said they are large, heavy and expensive compared to SOK or EG4. Roughly 2x the weight and 4-5 times the cost. 192lbs for 130 amp/hour at 48v for a van/truck/car is really, really heavy compared to other options. That said, they are very, very nice batteries.
I agree with you. This won't be for everyone. BTW, the 130Ah is at 90% of the total capacity. It's rated very conservative.
@@DavidPozEnergyid love to see a growatt 12 kw low frequency inverter test
@@DavidPozEnergyhow much are each individual battery?
Whats best battery for golf cart W inverter ? 400a max?
I thought I would ask if you know the answer to this question. I have a off grid 240 volt electrical panel powered by two LV6548 (SunGold Power) inverters. Since they are the my new grid, can I add 7 - 215 watt 240 vac Enphase micro inverters to my off grid electrical panel with damaging my main inverters?
Not that model. Some inverters will support "AC coupling", but they tend to be the more expensive inverters.
I hope the wall mount works but with two batteries mounted on 24” OC studs you’re only going to catch one stud. The 400lb load may pull the ply layers apart or allow the screws to pull out of the ply. You might consider some horizontal strips of steel, lag screwed into your studs 24” OC behind the ply, and bolt through the back of the steel and plywood to mount the batteries into the 16” OC holes as designed.
True the weight pulling on the threads may separate the layers of his 3/4 plywood but did you notice that those lag bolts have at least a 1/2 in shoulder on them so technically there's only a little over a quarter inch of thread engaged in that board! Hopefully that chip board behind it is really strong!
Just use strut
Just a question on the communication link, why use the splitter and a termination plug? Can you just plug the cat cable into the battery?
No, you can't simply plug the cable directly into the port. You are required to use some type of splitter and terminate the end of the "daisy chain".
I have 4x 48V EG4 server rack batteries and Growatt 5k inspired by one of your previous videos but I guess it's time to upgrade!
If it ain't broke, don't fix it.
Great video but the discharge floor (in the victron shunt) was not set correctly.
Question:
Any idea who makes the plywood box steel banding?
Nope, sorry.
nice test
have you work with sandi solar inverters 20 kw/30 kw are they good
David you are the one that led me to Growatt and now this. The enter key of my SPF5000 ES refuse to work, now the inverter can not enter settings mode. The most annoying thing is that I bought 5pieces from Dubai and I am in Nigeria.
Amazing battery system... thanks, Solar Jesus!
LMAO @ Solar Jesus!
How many time will I be able to charge my s23 ultra?
Hi, my Transit has two 250A 12v alternators. Is there a MPPT charge controller that can use 500A 12v DC to charge my 400AH 12v DC lithium battery?
Not that I'm aware of.
Most Van conversions I've see will use a couple of the Victron: amzn.to/431IvTH
David you could do this add a sub bus bar closer to your batteries then run smaller wire to sub bar and a heavier wire to main bar.
Absolutely!
What a beast!
I'm afraid to check the price.
$4500 for 1 battery. Expensive
Id see them in 12v capacity so I could add as needed ! Some people just don't need that much power, like my wife and I !
We are pretty frugal with power usage !
Why didn't you use just the Xan bus? You could save one terminator and the Schneider system would see each battery individually, including charge/discharge rates, right?
FYI enjoy it for the little time they gonna work, Discover used a cheap BMS and at least here in PR they have a high failure rate and you can find a lot of them on recycling centers in the US.
That's foolish of them. Any teardown video online?
@ ad on, Yes, Discover Battery has a good video looking at the internal parts: ruclips.net/video/o2QERMxzfZg/видео.html

Looking great bro with that beard :) Kudos to all the Engineering
I have the eg4 server rack batteries. They are UL listed but way cheaper.
I looked up the specs on that battery and it's about 200 lb which is about equivalent to 14 KW hours of lithium iron phosphate cells. It seems that for that weight this battery should be capable of much more output than 7 kilowatt hours.
As others have stated Great Video. How many of these batteries are you going to use for your home? Thanks Again
The two batteries in the video are going to be paralleled with my existing battery bank for powering my house.
Hey Dave, this a question about the 6kwh LG chem battery you built 3 yrs ago. How did it do? Are you still using it? Any other thoughts about it?
Thanks.
I used it for about a year before moving things around. When I removed it from the wall it has sat on my shelf, un-used. I never had a problem with it when using. I should probably check it again. Just now I looked at it and nothing seems out of place, no corrosion. Still has proper Voltage. There are just easier solutions today. You can buy prismatic LiFePO4 cells to DIY a battery and everything bolts together.
