Installing 2 group 31 deep cycle AGMs up front for 24v Terrova. I am planning on running dual batteries on 12 volt system for outboard and accessories. My question is , what size/type batteries do I need for outboard (60hp 4stroke EFI) Helix 9 ,Helix7, livewell, 2- 10 foot LED light strips, bilge pump ? Would start or deep cycle be better in this application ? What group size ? I have plenty of room in rear since I am moving trolling batteries up front. Thanks in advance.
