good luck, be careful not to parallel the sealed batteries, the steeper temp/voltage curve increases the possibility of thermal runaway. C&D makes a good sealed battery, check with battery services group, or C&D also Trojan makes smaller sealed batteries. I like Outback because of the battery monitoring/control capability of the FNDC.
