Module with 4x Sony 26650 US26650FT 3000mah Lifepo4
Here are some nice 4 cell modules in 2s2p format. They come with a BMS as well. The BMS appears to be a 5a BMS but might be a 10a BMS. These packs are used but are really nice and they use brand name 26650 Lifepo4 cells. The cells can handle 30a (10c) discharge. These are medical batteries and medical batteries typically only get used a small amount before getting replaced so the cells usually are not very degraded.
Cells are Sony 26650 US26650ft. When the cells are new they are 3000mah.
