One of our customers in the US went bankrupt, and left us 40 or so pallets of new LFP cells.
They are cylindrical, 15Ah, 48Wh, 3.2V, optimized for high energy density, manufactured by Gotion.

We don't really need that many batteries for anything, so if you have some EV or ESS project where these could be useful, let me know.
They are stored in a warehouse in Hayward (California).
We also have some pallets in France.

The price is 15 USD per kWh, each pallet is just over 100kWh. There are 5 boxes, each box with 432 cells, so 2,160 cells per pallet.
The minimum quantity is 1 pallet, they just come complete like that, sealed from the factory.
The EU located ones, if someone is interested, are more expensive (20 EUR per kWh).

If you need any other info, just write me a message.

$15 per kwh is a great deal. Do you offer shipping? If so, how much would it cost approx?

It's currently stored at a professional logistics company, that deals with lithium battery storage professionally. I suppose that they can help with this topic. I know very little about how the shipping around the states works. For those that want some pallets, I would put them in touch with the logistics company and let them figure out some shipping agreement.

But in all seriousness, that's an absolutely outstanding deal for a DIY crowd like ES. I hope they find a good home promptly!
 
Too bad that the cell doesn't have an easy way to weld to it. Otherwise I'd buy at least a pallet. 😢
 
You'll notice the ends are big beefy copper tabs, able to diffuse a bunch of heat. And LFP in generally is good at handling short bursts of heat, more so than li-ion. Therefore, you can solder these. Could get some pretty beefy connections this way.

For example:


You'll still want to exercise caution, not to let the cell heat up too much, not to have solder drip onto the canister itself if you can, etc.
 
I have a bunch of these too. They solder really well. Freight would be around $400.
 
Wish the warehouse was in Phoenix so I could go pick them up and save the shipping cost; I'd seriously consider trying to borrow to get these to build new batteries for the SB Cruiser and the new trike-in-progress. AFAICT from the spec sheet, it should handle 30second peaks of around 100A at middle of SoC with a 1P configuration, so I could use just 16 cells at around 10lbs of cell weight to operate the SB Cruiser as far as startup from a stop goes.

I couldn't find a clear statement or spec of continuous discharge rate in the spec sheet PDF--plenty of data on peak or pulse charge or discharge, etc., but not continuous capability. I require at least 30-40A continuous just in case I have to go up the 7th street / cave creek route up north mountain (very rare, but *have* to be able to do that) and in case I have to haul heavy loads in adverse conditions (gusty high winds; also very rare, but *have* to be able to do it), so that I can just carry a second pack for those specific circumstances to get the 60-80A required to maintain 20mph up that hill or haul heavy stuff in winds.

Assuming that 1p can handle 20A continuous, then to effectively replace the aging 40Ah (maybe 30Ah really) EIG pack, I'd need a 2p configuration for 32 cells total, around 20lbs, and around 6" tall by 11" long(8 cells) x 6" wide (4 cells). Doulbe that if 10A is the max per-cell continuous current. If it's less than that, they're not useful cells for my purposes as I'd have to have too large and heavy a battery.


With an entire pallet of >2000 cells, there's a decent chance that enough identical cells can be found to make 32-cell packs from so that balance won't be an issue during the early lifetime at least, so that a BMS can be avoided and just use manual periodic testing.

So then that uses up 64 to 128 cells, and I would just have to figure out what to do with the other couple thousand of them. :lol: (I would not want to build battery packs for others, even locally; too much liability; same thing with shipping cells anywhere.)
 
I think @Zambam was using them in 1S configuration in a scooter for a short period and getting 2C out of them during short hill climbs.

The canister is not grounded AFAICT. Varying voltages can be measured from either terminal to the canister. Sum of both readings = battery voltage.

I built two packs of 22S 1P by soldering, first ran just one pack (15Ah) then ran both in parallel (30 Ah). Have around 400 miles on the battery so far in a 200 lb moped with 1500W motor. Battery working great. Getting 60+ miles on the last full charge (22S 2P).

Hey, this sounds really interesting! I’m working on a small-scale EV project and these LFP cells might be a great fit. The specs look solid, and the price per kWh is really attractive. I’m based in California, so the Hayward location could work out perfectly. Could you DM me some more details on the pickup process or if there’s any flexibility on the minimum order? Thanks!
