I’m researching battery options for building my own pack. I want at least a 65A continuous draw battery pack and around 7500mAh to 10000Ah capacity.
li-ions 18650’s seem to have a decent capacity, but too low of an amperage for me: 2500mAh, 20A cont.
A123 Lifepo4 have great amperage, but lower capacity, and expensive, as a bonus they have GREAT cycle life: 2300mAh, 70A cont, >1000 charge cycles
neither of these looked appealing to me, so i went searching. I found these just now: http://liionwholesale.com/collections/batteries/products/basen-4500mah-26650?variant=14135870212
4500mAh, 40A cont., and they are cheaper than A123 cells.
If i bought these i’d likely do a 10s2p or 12s2p: 9000mAh, 80A cont.
