I’m still deciding between them. Battero and EVE
The battero are the most affordable.

I'm ordering 8 of the MB31 cell from Jenny Wu... I don't mind the 60 day wait time, I've placed 3 or 4 orders from China in the past few years and never had an issue with my orders (other than the wait time, but that was expected).
Ray's video is what sold me on this order... I like the fact she includes the battery separator sheets. It's a small thing, but appreciated!
I'll let you know what I think of them in 2 months

I’ll know by tomorrow about a purchase for 16 cells rated at 304ah. Fedex delivery. Got 2 each jk-200amp bms should be here by friday. I figure 45kw battery might be better. Maybe…
going to see how this build does…hopefully battery build box will be here before End of July. I may take measurements and build my own boxes. Act like chinese.
Maybe it all goes good maybe not.
Good ol FEDEX delivered 3 boxes out of 8. Other 5 are suppose to be here tomorrow or so. Fedex is terrible about - for losing MY packages.
The cells are nice packaged 2 per box…come with bus bars and fiber separator sheets. No scratches on batteries perfectly flat no bulges in fact they look brand new. 280ah but advertised as 300ah + for capacity which remains to be seen. Otherwise everything appears as advertised and better. Appearances speak volumes. The price was very good… $1512.00 Cheaper then buying factory packed batteries with unknown cells inside. A single Chins 48v 100ah factory pack was on sale for ~$1100 at the time bought these cells from Jenny.
Jenny Wu is the real deal. These were American - USA stocked with Ultra fast shipping. I am impressed so far. Delivery delayed for rest account of Fedex. Maybe later today or tomorrow…..
Now waiting on AliExpress deliveries too.
Got 1 item - N.m torque wrench set today will know how it works when assembly batteries - to torque bus bars and other electrical connections. I can’t find my torque screw driver anywhere so….this will do. The ratchet is ultra fine tooth and smooth and the torque adjustment is smooth for torque settings. Pleased with AliExpress delivering as advertised too. The JK-200 amp BMS are suppose to be here tomorrow.
Feels good to buy pass Amazon. I might buy next set batteries from JennyWu or spread the wealth to another. No loyalty. It is mostly gone in business after all business is business. So am not pushing JennyWu but the service so far is above expectations.
Anybody using one of these?

Got all 16 cells in for my new battery JennyWu delivers and that was most pain free service had in long time. Me love you, Jenny. .my name is Forest Gump.
Got both of my jk bms JK-B2A20S20P-HC in from AliExpress. All am just waiting on now is my battery build box. Looked at bottom of my cabinet again and might get a set to fit in bottom of it…then would have to order 16 more 280ah cells for the pre-made diy box. So far am pleased with AliExpress. I don’t like Alibaba. Tried to buy a USA spec 120/240 split phase Deye 10kw inverter 3 or 4 times but found they are to wishy washy. Lack confidence. I may buy another MPP Solar 3048 from Watts 24-7 and run them split phase 120/240 vac. Idle watts will be ~85-90watts for both. Hmmm …. I’ve never seen anyone running 3048 in parallel split phase. 2 is 1 and 1 is none.
This jkbms they advertise and sell on Amazon is $284.99 - $214.99 with $70 discount. Wholly sheep shit fleeced. On AliExpress same jk bms is $97 so boy scout said buy 2 but should of been 3. Two is one and one is none. Most everyone has been out of bms …. The Cells that I was going to buy from Gobel Power are now on back order….. Wait List.
Me realizing could fit 2 rows 16 each per shelf of 280ah battery cells in my existing roll around emergency solar power - metal cabinet. 30kw. Probably only put them on very bottom. The shelve rate is only around 100 pounds each and 16 cells are around 208 pounds. But the bottom shelve is reinforced…no problem.
Cells fit good.
How many ppl are on solar here? ? If you are preaching it you damn well better be living it? Green Energy is shekel … expensive…. For every dollar we save can send two dollars to a foreign country so our politicians can get a dollar back for themselves. 2 for 1 deal with them. Support USA Govt. just do it change we can believe in.
Buck up. Should I insulate the metal shelves? With what? I think C4 vette Composition C thermal paste on bottoms. I can pop hole in cabinet ends to put in cell compression too. Just can’t squeeze it to tight. Boom. Any advice on the proper compression amount. I’d bet they don’t worry about that with factory pack batteries like Himassi on the bottom shelf right now. …..
I want to run the mini split so I have no global warming on my private and the hairy beastie friends this summer when blacked out. You know when the grid blacks out from being old and over loaded. I lived in a desert for few years crawling around in it … hot as mf’er. I don’t plan to die from old over loaded non updated neglected grid going down - passing out before the reward because some yuppie up the street plugged up his EV. Old mf’ers are about done carrying the loads.
Fad monster wanna be then saying see black out caused by Global warming. The fact is shit heads sent all our money to foreign countries vs spending it HERE on upgrades and required maintenance practices HERE. Now we are broke as a mf’er ~$35 trillion dollars in debt and everyday my savings drop more. Already cut in half from before Biden came into RULING THIS USSA until now. Some butt munch wants to say it was Trump….that robbed me. Hahaha say Show me ….. your solar array…..mf’er. New Green Deal is transfer of wealth. Make plans to make it easy on yourself for as long as you can.
Making bacon topped off batteries no required load for himassi battery set. Those batteries were around $1100 dollars for 5.1kw now for $1512 bought around 3x as much. Smile. 600watts idling… offsets the inverter and Raspberry PI400 easy peasy.

.Did you order the REPT or EVE from her? Did they come with the insulation sheets?
I'm going to order the REPT today or tomorrow.
I'm a big fan of the cutting boards from Sam's Club or Costco for the bottoms. They are slippery and fairly thick plus they make a great mess when you rip them down on the table saw.
Ali is the cheapest I've found for my JBD's, I've also ordered them from Jenny with cells.
I too tried getting a Deye, maybe someday.
I'd use NO-OX ID A special on all bus bars and connections.
I don't compress, just restrain. It's ghetto but it's been working great.

If we think about it will realize none of batteries are compressed …. In factory packs just contained. I’m not sure compression is a great idea. I’d rather they expand a tad vs popping. … when you compress something and it lets the smoke out not going to be good.I love your posts man, can almost always get a smile and a laugh, Forest Gump

I almost had one for the 10kw Deye 120/240 $2000 shipped but seller came back and swapped it for some water proof SRNE 10kw. Never heard of it. “Some spiel about USA all locked up.”….. “No Deye” They advertised Deye split phase 120/240….Alibaba.
Sheets came with cells as did bus bars. Got extra sheets from AliExpress. I am liking it so far. Alibaba is wishy washy. I’d figure the bus bar need it too. These EVE 280ah cells from jenny are 2 to a box. They are suppose to test over 300ah.
I may order set from Gobel Power
Next time drive to Florida might stop get a set of these. Not sure which like better. The bus bars are more robust. The flex bus bars might be the best to allow things to move.
42OhmsPA
What's in a title?
I'm using both types of bus bars. I prefer the flex type due to seeming to be more robust.
My Envision cells came from 18650, no complaints, I wouldn't hesitate to do business with them again.
EVE does call out compression, iirc you can gain some additional cycle life but calendar aging will likely win, or a new technology.

D71, did the math, prismatic cells worked better on my slide ruler, seemed to shorten build time also.
this would drive a nail through my head, going to build my own box.
Seen few videos the prismatic are probably safer. Maybe. Swelling. The dimensionS are here on these boxes for 280ah + cells.
I ordered the EBC-A40L cell charger tester to check the claimed capacity but it has not arrived yet either.
Like this one with120vac plug. Almost ordered wrong version - plug. I ordered mine from different source this is reference. These testers can be graphed with computer while testing cells.
I may buy more prismatic cells for that case when it finally gets here in AUGUST and use the CELLS have in bottom of my current roll around cabinet.
Damn this thing took while get here. No manual in english. No software….in box … Not very global of the chinese to exclude other languages?
I almost messed up got wrong cord vs 120 plug.
No software either. I found them online from other sources.
Hmmmmm over priced.
The laptop connected makes setting parameters easier. Graphs….
I don’t think it was really worth the money. Standard power supply is probably better can use them for other things. Some ppl just assembly batteries into pack …. charge and go. Hmmmm…

Yeah.
Bring on the midget porn. Mine is cable laptop dancingI gotta restrain the cells in an unknown compression amount to test them. The advice is all over the place … most ppl do not agree. Some ppl stated don’t worry be happy….no compression.
I ordered the battery box as described and selected because stacked weight of the cells should compress with exception of last cell. The top retention panel of battery box offers some fitment for tight fit with it. Nobody wants a box that is loose.
Lot of ppl just using wood. Vs box ……thread all with pex covering the thread all …… where it might contact cells some straight row 16 some 8 side by side. Lot of interesting stuff online. Been looking for a while.
They need multi-language instruction book in box.
I found deye the other night. $$1825 for 8kW 120/240. They wanted like $2100 for shipping. Fookers… 
Edit To be clear they wanted total $3925 total to include taxes and other bs charges.
USED…. SMA SUNNY ISLAND are cheap on ebay

I was getting impatient like kid waiting on Christmas. Got notice my DIY battery box will arrive around 5-6 days from today….that is a lot better then 3 Aug. that boat was getting it to make it this fast. If it is problem free - respectable delivery time. Will order more.
25-26 June delivery vs 3 Aug from AliExpress china shipment - boat.
So far am liking AliExpress hope this doesn’t jinx it. UPS can ruin a wet dream. It is in their hands.
Them and Fedex are awful sometimes. US POSTAL is best for me.
I was looking at these battery holders. Put the fiber board in then battery cells and fiberglas tape up.
