Yes Sir, no worries Gary. You have more than enough power supply. I cannot see any need for you to charge at 22 amps on 3S or 17 amps on 4S unless you are doing parallel charging. You basically have 200 to 400 % more power than you need. It is overkill for what you have now.

Yes it is a copy and has the exact same requirement of needing a 24 to 30 volt power supply to take full advantage of its power capacity. Lower voltage means less power available.

Power or Watts is a product of Voltage x Current, or

__Watts = Voltage x Current.__ The Charger can operate from 12 to 30 volts as a variable of Voltage. Current Input is limited to a maximum regardless of Voltage. That limit is roughly 13.5 Amps, so if Current = 13.5 Amps is a

__ fixed variable__. With a 24 volt x 13.5 amps current input is 320 watts roughly. At 12 volts x 13.5 amps = 160 watts. So as you can see, the lower the input voltage means less power.
