My electric boat has LYNCH electric motor at 3 mph it draws 20amps ish at 24 volts.
The new batteries I have bought 8 x U27 valance lithiums will be arranged in four in series twice and then in parallel to achieve 24 volts. All the batteries have a BMS and I have the software to talk to the Bms's and can balance them doing this, however I would like this to be automatic every time they charge and discharge, Valence havnt replied to my emails so has anybody on here got any idea how I can achieve this or do I even need to do this?
Many thanks in advance
Peter
