I have a 60hp 1996 johnson o/b to which I am currently adding a perko 4 way switch and a deep cell battery for a trolling motor. My concern comes from reading a couple of older postings that talk about never charging a deep cell with anything except a trickle charger. Does my O/B charging system have low enough amp output to prevent damage to the deep cell battery when I am running my motor and switch to recharge the trolling motor battery? I have had this setup on a boat previously, but I never looked to see if there was a regulator between the switch and the deep cell.
