Hi Colleen - are you building your own battery packs? I guess the other question is - are you using a charger with cell balancing capabilities?
Suspect we're looking at very different approaches as I deliberately chose high capacity 3 cell battery packs wired to deliver 11.1V, a lower amperage draw and with the voltage protection cut-off circuitry built into the light, not the battery. IMO that kept things simple, lighter and cell balancing is handled by the charger.
