Interstate 6 Volt Deep Cycle RV batteries - Heartland …
2014-3-9 · After reading the posts on the batteries set ups .... I'm thinking on going with 2 Interstate 6 volt deep cycle batteries instead of 2 - (group 27) 12 volt batteries. (which would be a better set up, right?) I have seen others going with Costco's brand..... BUT where I live we don't have a Costco. So started looking around here close to home and found the Interstate ones (the GC2).
