Sorry for the bump on this one, but I would have posted the exact same.
I just picked up a generator. its 2000/1600 watt.
When the genny is plugged in, the voltage get up to 13.3-13.5.
And I never seem to get a full charge.
I have two GC2 batteries with 230AH ratings (Total 460)
I'm considering buying this
BLACK+DECKER BC25BD charger. It's a 25amp charger and wondering if it would make the charging a little quicker over using the built in charge coverter. The converter that came with the trailer is a smart 3 stage unit.
Thanks
