Looked over some old threads and couldn’t find the answer. I have a deep cycle battery I throw in the back of the boat and run a trolling motor for a basic set up. I have a Resolute 27 Group Size. Can’t seem to find reliable info by google. What is the best way to re-charge ? Slow at 2amp or 10+ amp? Can a basic car battery charger be used or do you have other recommendations? Trying to avoid spending significant money on a charger . Thanks !
