Biggest lto cells?

[outboard1196]

I'm researching LTO battery bank as I need new battery's. I have lead acid and was planning to stick with lead going forward as I need cold temperature performance. I need 200-300 useable AH capacity at 24v. Seems the biggest lto cells I can find are 45ah and buying from AliExpress which I'm not sure I would buy from that site to begin with. With those prices I'd be same or higher price then buying flooded batterys. Any cells from US sellers that are fair priced? Are there larger cells? What BMS is recommended for LTO?
Thanks

Why are you going with LTO? LFP has a very nice cycle life and prices are coming down splendidly. Just buy 8 M30 EVE cells and make a great battery for your needs at less than $800 plus BMS.

I agree, any need for the LTO?

Don't get them off of Aliexpress - too many scams, especially the LTO cells. There are a few sellers on Alibaba - look for those that are verified, have a couple of diamonds next to their verified icon, and have been around for some years.

You will have trouble finding large capacity cells; many (most) of the packs out there use cylindrical cells.

The JK BMS supports LTO.

I understand you want them for a cold climate, but consider adding a small heating element to LiFePO4 cells and house them in a well insulated enclosure.

Battery hook up has some right now. No idea when they will run out. They had some smaller prismatic cells a while back and I thought they would last forever with 6000+ in stock but sold out in a few months.
100 bucks for 6x25ah right now. Cylinders.
Probably your best bet, lots of scams online and dubious sellers.

I did see those, but I went with lifepo4. I'm tempted to buy some to play with.

LFP is cheaper for sure. Small LTO cells have my eye for outdoor solar lights and fence chargers though. A battery that can hold up to time and very cold resistant would be perfect for outdoor projects. None of the other lithium chemistries come close.
