What is the point.
I am changing my Converter Charger and my 2 batteries. I now have 2 Costco # 27 12v deep cycle 115 AMPH each which would give me 230 amph total. If I go with 2 6 v golf cart batteries at 232 amph e...

The way I understand it, any flooded lead-acid battery should never be discharged less than 50% without causing damage to the cells (hence shortening the life of the battery). Given the data you provided, 50% discharge of your 12v battery yields approx 57 amp-hours. x 2 is 114 ah total usable capacity. The 6 volt batteries at 50% give 116 ah EACH, so you should have approx twice the usable amp-hours if you were to change to the (2) 6v, which are true deep-cycle ones. The 12v are likely trolling-motor style, meaning they are capable of providing high amperage discharge rates to start things, not just a steady discharge like a true deep cycle. All the other comments on 12v vs 6v are accurate, meaning one dead 6v battery leaves you out of service, etc. But unless you do a lot of extended boondocking without either running the engine driving about, a generator running, or solar panels, then having the extra battery storage capacity is rather meaningless. Hope this helps!

Actually that's not how it works as far as amp hours. That 6V's and has to be doubled to 12V, so the two banks he is comparing are really just about equal as far as amp hours. Otherwise you are dead on.
