maximizing battery capacity
I have an 8 foot camper with a 100 watt solar panel and charger. Right now I have a group 24 12v battery and would like to increase the amp hr capacity, I was wanting to run two 6v in parallel but I c...

It's a server or host issue. Has been like this for a few weeks. Can read but can't post half the time. I go to Woodalls when it does this.
Nuckfan: sorry if it sounded cryptic. I'm still a dummy compared to top guns here.
C is a nominal battery capacity in AH, and recommended charging current is measured in %C. Ex., 0.15-0.2C (typical for wet battery) means 15-20A for 100 AH battery.
SOC = state of charge, or how "full" it is.
Absorption is the stage #2 in any (decent) charger: #1 Bulk (high current, voltage is rising to 14-something), #2 Absorption (voltage is kept at 14-something and current is tapering down), #3 Float (voltage stays at 13-something and current is very low).
When it goes into Abs, battery is 80-90% full and from that point on it doesn't need a lot of current, and small solar can handle this. Having a bigger battery bank helps, since 50 AH drawn from 100 AH bank leaves it 50% full, but same 50 AH off 200 AH bank means 75% full. If you do need to use a generator, do it during the 1st stage, to bring SOC to 80-85%.
