high rate charging on generator
Hi all, The batteries: 556 amp-hours of surplus acid AGM batteries 12 volt jars 105 lbs each. They are wired as two banks with balanced wiring. The depth of discharge: 12.1 volts under 425...

I am doing a recharge while camping right now, using my adjusted PowerMax PM3-100 (PF corrected) set to 14.8v and recently acquired adjustable voltage PM3-55 (non-PF corrected) together for the first time on four 6s at approx. 50%. SOC
The Honda 3000 ran them doing 156 amps no sweat. (I kicked off with no eco then turned eco on so the Honda wouldn't conk out at start up like it will sometimes in eco.)
I only got about five minutes of that 156 before amps started to taper, but I was able to get the amps back up by cranking up the voltage on the 55 from 14.8 to 15ish (batts at 14.1 at the time)
So--it's not the Yamaha 3000 in the OP. It might be acceptance rate of the batts including the R from wiring and connections, so the batts are not taking 125. Or the charging voltage is too low to meet a 125 amp acceptance rate. Or there is too much else on to leave enough 120v to run the charger.
Somebody here with a Xantrex with a 150 amp PF corrected charger in it reported a while back that he gets the 150 amps ok.
