Hi, I after a while going at it for a few months I made the smallest 40amp pack I could. Let me know if someone would like one its difficult to make so it does cost a pretty penny. PM if intersted
Oh yep 4 3s lipo’s in series rated at 20c. Each lipo cell has a balancing chip as well as over discharge and charge protection all tied to a temp motoring bms system. Capcity is 6000mah.
