- NiMH: Set power supply at 1.2V with current limit depending on the battery's capacity (ex. if 2500mAh, then set current limit at 2.5A). For multiple batteries, connect the batteries in parallel then set the current limit based on the battery set's capacity (ex. if 30,000mAh, then set current limit at 30A). Lower current limits are ok, but they will result in slower charge rates; higher current limits are situationally ok- if excessive current is channeled for too long a time, then the battery will overheat.
