Charging a Battery Bank
I am planning on upgrading my batteries to 4 6v batteries wired in series and parallel to have a 12v system with plenty of Amp Hours. There is a ton of information on how to wire things up but nothing...

EDIT--at the same charging amps and absorption voltage, if you double the size of the bank, it will take twice as long to recharge it from the same SOC. However, if you double the charging amps, same Vabs, it does not halve the time on the same bank. There is a diminishing return in time from increasing the charging amps.
I haven't noted any indication from the OP that he intends to "double" his charging capacity in order to best match the charging requirements of four GC-2s ... rather I suspect those four batts will end up being recharged at a far less favourable charging rate, so perhaps you'd clarify this for us in layman's terms ... :W
If you have two GC-2s drawn down to 50% and it takes X hours to get them back up to 90% using the trailer's existing converter / charger (for example WFCO 8955) powered by a genset (say one of the popular 2000 watt inverter models currently available) then four GC-2s also drawn down to 50% won't take just 2X hours to get them back up to 90% but 2X+ hours ... correct? :h
If that's the case I would have thought this would be all the more reason to stick with just two GC-2s and plan on recharging them each day as necessary, assuming of course that two will get you through at least one 24 hr period without recharging.
