Where to buy cells?

[Vlaario]

Hi im shopping for 16 batteries as well and going to try my luck with these ones https://www.alibaba.com/product-detail/EV-E-V3-280Ah-Battery-LF280K_1601076859939.html

wistek alibaba shop 36 euro for eve LF280K v3 seems like a good deal.

off course this was too good to be true ...50.86 ex from china europe stock sold out as well. but after a conversation they where offering the 314 MB31 shipped to netherlands from eu warehouse for 79usd.

I just got a quote from Docan (Jenny Wu) for 280ah 16S Hithium at $42 each total shipped USD to Phoenix was $913. DIY box with a BMS shipped was about $500 shipped. I could be wrong on the DIY box shipped I never got a full quote it was $390 before shipping I'm just estimating shipping and fees. Total cost about $1400-1500 for 14.5KWH DIY battery. I bought a set from her in December took 30 days from the day I paid to having them put on my porch here in Phoenix. Compare that to a EG4 power pro about the same capacity 280 amp 48V price is about $2500 difference. You get a UL listed battery, US support, and a long warranty. China you may or may not get a warranty I do know shipping them back cost more then the value of the battery. I have heard Docan shipping a replacement battery without requiring the bad one returned after some troubleshooting and proof with a video or pictures.

IMO DIY kit box is the way to go get a BMS with it except if you are shelf mounting on a heavy duty shelf that can hold the weight. Personally I would put them in a metal box if they are in my attached garage maybe I'm overly worried about fires. If I had the room just build a battery shed or buy a shipping container. Problem here is the heat in the summer doesn't pay to AC a shed when I can AC my garage use it for other things.

Over the past week I've reach out to quite a few suppliers on Alibaba and some others in the US or Canada. Most of them replyed that they can't ship to me and the ones that said they could would end up costing over $200 USD/KWH after shipping.

One of the few suppliers who claim they can ship to me was Exliporc on Alibaba. I felt uneasy about placing the order but I gambled and paid 50 USD each for 8 Hithium 314ah cells. If they can actually deliver usable cells to me then I figure I can put together the rest of the materials to build the pack to cost somewhere around $100 - $120 USD/KWH.

I'll update as the cells are shipped and when/if they arrive I'll post some photos.

Thanks to everyone that made suggestions so far I appreciate the help.

The problem with the hithiums is they seem to have overwritten qr codes, so it explains the very low pricing. Generally the diy box shipped from China is pretty expensive for shipping by itself, unless you bundle with batteries. They have the Apexium diy box ex Houston for $640+5%, think you may save $50-$100 by waitng for China boat.

It may make sense to build for a large 48V system but no so sure for smaller systems. I'm running 4 100Ah LiFePo4 that ran me $175/ea in 2S2P for 24V. Going to add 2 more so I'll have system like the OP wanted (24V 300Ah) for $700. Pricing cells from US distributors the going price seems to be around $47 for a 105Ah EVE cell. That's $1,128 in just the cells, never mind BMS, bus bars, etc.

So far with 4 batteries I've had no balancing issues. If that changed going to 6 even adding some balancers it's still way under the $1,128 price tag. Funny as I'm writing this I got an email for the batteries for $169/ea shipped. Going to have to order them up now.

I love doing DYI stuff but not when it's going to cost substantially more than prebuilt.

DIY 8 300+ ah cells and BMS can be built for around $750.00 Why would you compare or consider 24 cells in a 8s3p or 3p8s configuration when you can do it with a simple 1p8s configuration?

How many here have received overwritten QR codes from Docan? Jenny Wu sent me pictures of QR codes with a spread sheet test results I suppose it could have been made up. The EVE's I received back in December QR codes matched what was in those test documents. I just put them in service so far so good who knows.

Yes the Apexium DIY box my thought was if you ordering cells from China might as well include the DIY box and save $100.

You can get 280Ah cells from Gobel USA stock for $1500 including shipping. Depending on how handy you are a BMS and a box won't cost $900 additional. But a pre-built being ready to go is certainly worth something.

I don't get your point. That is a pre built battery from Gobel which is not at all what I was referring to. And if I want 48V, I'm not stringing 12V batteries together. A bunch of parallel strings of 4x 12v batteries is a total hack job at that point and bound to have all kinds of battery balance issues.

Works for me and I liked the price. They balance better than some of my LiFePower4

Well yeah you added an equalizer to them to make them work together.

A $60 equalizer was delivering 14kWh of storage for less than $1700 (four ecoworthy or dchouse 12V 280Ah in series). Yes, it's an extra component but unlocks a significant value in terms of $ per kWh.

I had them and decide to use them. It was fun and successful. I'll eventually cut them open and put them in a box when I find one at the right price. Not many 100-105ah cheap boxes. Considering a 19" rack mount enclosure.
$151.99 x 4 + $40.66 = $648.62 for 5KW 48V
