Here is the scoop. Fished all weekend, using my Minnkota trolling motor. I have two batteries in the bow storage, separated by a Perko switch. Left the lake this afternoon, unplugged the Minnkota, turned the switch to "off".
Got home and went to charge the batteries using a portable, manual battery charger. Opened the storage to the smell of an electrical fire. One battery (Costco, about 4 months old) has the positive terminal completely melted. All cables to the battery are melted as well. 2nd battery (about 36 month old Interstate) has cables melted (not as bad) and a spot melted through the top of the battery where a cable was on the top.
Boat is all original from the factory, with the exception of the battery exchanges that I have done myself. I have used the boat at least 15 days since I changed out the latest battery.
Any idea what could have caused this??
