DIY 3S Lithium Ion Battery Pack : 5 Steps (with Pictures
Another option is the 26650 lithium-ion cell, which has a 5Ah capacity and requires only three cells to replace a lithium-polymer battery. Since a 4-cell LiFePO4 pack (12.8V) is farther from 11.1V than a 3-cell lithium-ion pack (11.1V), I chose the 26650 option. It also saved me cost as I only had to use three cells instead of four.
