So far I can get about 15 amps into our RV's AGM battery bank from our EX650. I do this using an old Sears 2-10-50 charger (set on 50 amps) hooked up to the batteries in parallel with the RV's stock 13.6 volt converter - both powered by the EX650 while the EX650 is at the same time hooked up to the RV's 30 amp cable so other stuff inside the RV is also being fed by the EX650.
I'msure the lowly 15 amps is not due to the EX650 being only 650 watts. The lowly 15 amps is most likely due to the interaction of the converter's output stage voltage and impedance with the Sears charger's output stage voltage and impedance when the Sears charger is set to it's 50 amp "motor starting" setting.
Powering just one charger of the right design, the EX650 should do it's full 650 watt thing and get 30 or more amps into a battery bank - at least certainly do 30 or more amps into a low internal impedance AGM battery bank.
