Because the pack will have all the cells in series, they carry the same current during charging. One way to address this the charge issue is to provide a full charge (charge to capacity) to the batteries even if it means overcharging some cells and dissipating the extra energy as heat. Overcharging occurs when the some of the cells in the series need less charge while the others receive a full charge.
Decision:
Upon review of the NiMH 10S 1P battery made from Turnigy cells, it was determined that this is still the best choice. The batteries are:
Easy to recharge
Is allowed by current regulations to be an aux. battery (Li-ion not allowed)
Allows for 45 mins of debugging time at full LV load (80W)
5000mAh X 12V = 60Wh
60Wh / 80W = 0.75h = 45mins
