Charger selection help please
I'm thinking about buying a Noco Genius G26000 26a smart charger for when the sun isn't getting my batteries charged. I have a FR Stealth Toyhauler with two Interstate GC2 208ah batteries. They do...

Thanks, so the Magnum is a little more efficient ( 87 vs 80 ) than my 100 amper, so scaling up doesn't go as high as I posted earlier, but it still goes way up.
Another thing is the (loaded) input voltage with the Honda was 123v while the Magnum figures are using 115ish. Since that voltage is part of the VA, that makes the VA assumed to be needed by the Magnum seem low. PT's Yamaha would have had the voltage above 120 too, so the VA in his case would be higher from that.
Anyway, even the spec 18 amps for the 125a output is well over 15 amps, so I don't think PT's claim that you can run a 125 amp Magnum charger at 125a output at 14.x volts from a 15a receptacle on 14 wire with a 15a CB is correct.
A mystery remains that he was using his 3000w Yamaha as the power source, so it should have worked with the Magnum set at 23a input.
