Decided to go with 2 group 27 batteries. Forgive my stupid question but here goes. Just wanna make sure I do this correctly. To hook the two batteries up in parallel I think I would do the following:
1. Run a jumper between pos posts on batteries
2. Run a jumper between neg posts on batteries
3. Attach Trailer pos to pos post on batt 1
4. Attach Trailer neg to neg post on batt 2
BradMy group 27 interstate batteries are deep cycle aren't yours?
yep, mine are deep cycle Royce. I got them spur of the moment at camping world when I noticed the fridge would alarm when I turned on any lights when loading.
