I'm running two of the 24Volt 12 amp ip67 chargers in parallel to charge 24V Lithium batteries that run a electric trolling motor. The motors maximum draw is around 75 amps.
What size generator do I need (in watts) so I can run both chargers at max rate (24amps) continuously whilst running the motor at 25amp draw?
Watts = VI
Volts * current. So simplistically 24*24. Or 576W. However the batteries will be at a higher voltage than the nominal 24, so add some margin.
