We are planning to do some dry camping so gonna run two 6 volt golf cart batteries. They should give a total 328 amp hour rating verses the 80 amp hour rating the group 24 that came with it has. Share the same opinion with the rest, if you'll always have shore power no need to change anything.
Cliff,
What size batteries are you planning on? My 2 T-105 size batteries are only 220 AH.
Think they are Exide GC110X and I think they are rated at 164 AH each. Will double check tomorrow and let you know. Haven't bought them yet.
Unfortunately, two six volt in series does not double the amphour rating. The Exide GC-110 has a reserve capacity of 186 AH. Certainly more that the Group 24, 80 AH you had previously.
Here is a link to some good information that has helped me in the past --> The 12volt Side of Life
Hope this helps.

I came across this article today. It says the low point in the cycle should be 40% (tomato / tomaato). Point being only 60-80% of a battery's capacity should be used. If you drain it down more than that it will shorten the battery's lifespan. So a battery rated at 70 AH has a useful range of 42 - 56 amp hours, 186AH = 111- 149 AH, 226AH = 136-181. We should end up at three times the Amp Hours we were at.
Good points Cliff on prolonging a battery's life by watching the cycling of the batteries.
The best way I have found to monitor my battery bank was to install a true battery monitor with shunt to measure voltage, instantaneous amp draw, and total amphour capacity remaining (like a battery fuel gauge) - I installed this monitor, Xantrex LinkLite Battery Monitor. An alternate that I know others also like is this one, Trimec Battery System.
