Recently I had one of my thruster batteries explode. Battery is a maintenance free only 3 years old. Battery was one of two 12 volt batteries wired in series. Batteries were purchased at the same time and installed together. Charger is a 24 volt Mastervolt that was new when batteries were installed. The explosion happened after I cranked the engines getting ready to leave the slip and tested the thruster with a short engage. The battery cables were tight and there is no arc indication on the posts.
This seems to be an internal event as the pictures show. It’s been suggested the cause is overheating caused by a defective charger. I’m not defending the charger, but if that is the case why did it take me energizing the thruster circuit to cause the battery to blow.
I’m just looking for ideas that would cause this.
