I have an Apache 2020 lipo charger and plan on charging a 3S 1200mah battery. The manual for the charger specifies a min and max input of 10.5-15 volts but not amps. I have an old Radio Shack power supply I'd like to use that is rated for 13.2 volts and 3 amps. From what I understand, the charger will output at 1.2 amps but how many additional amps are required for the residual functions such as monitoring the cell voltage and peak detection? What is the smallest amp rating on the power supply that I can get away with?
