Got 2 interstate group 27 batteries today to run in parallel for my 12v trolling motor...
1.. Will one bank charge both batteries since they are in parallel or do I plug the 2nd bank to the 2nd battery?
2.. Does a 2nd deep cycle battery give the trolling motor double the charging time or what's the extra time I will get on a full charge compared to using just one new battery?
3.. What gauge cables do I use to pair the 2 trolling motor batteries?
