When I purchased my barely used Sabre from a Ranger dealer,(former owner traded in on a 17’), they must have swapped out chargers. Mine has a 3 x 5 amp Minn Kota, but they also left another 5 amp single in the boat. I have never used it. Question is, if I ever needed to, can could I put those leads on my 31AGM that runs electronics/starter? That would mean two chargers on that battery at once ?
