Adding two 6v to two 12v?
Hi All, We just moved from a 5th wheel toy hauler to a new class A motorhome. I'm not sure if I should do another set of 12's or add 6's in series. In an ideal world I would swap out all to 6v's bu...

By the way there is a slight difference between most 12 volt (MARINE/deep cycle) and most 6V (Golf Car/DEEP CYCLE) batteries. the way I type it suggests.
MARINE/deep cycle you can safely use about 25% of the capacity. run 'em down to say 25% SOC and the odds of recovery are... SLim (not none but clearly slim)
DEEP CYCLE you can safely use 50%. Run 'em down to 25% SOC and odds are good they Will Recover (not 100% but way better than the MARINE type).
I would not call that a "slight difference" !
I happened to have had an email conversation with Trojan about this topic (The T-1275 is a true deep discharge 12V "golf cart" battery; The SCS225 is more of a "dual purpose" battery, one of the the few that Trojan actually lists "Cold Cranking Amps" for.)

The T-1275 is a higher capacity battery, rated at 150 Ah where the SCS225 is rated at 130 Ah. The T-1275 is a heavy duty 12V golf cart battery with thicker plates, which means it has a longer cycle life at 50% DOD, 1200 cycles versus 600 cycles for the SCS225.
Oh, the T-1275 weighs 85 lbs and the SCS225 weighs 66 lbs. The T-1275 is BCI Group size GC12 and the SCS225 is BCI Group Size 30H, so they are not physically the same exterior size.
