Two Batteries are my trolling batteries, hooked up to a switch to switch from one to the other,
one battery for accessories, mainly for use in my night fishing. I use LEDS, low current drain but I don't want to run the chance of depleting my main battery.
One battery for cranking my main motor .

I would guess that the battery developed a short and kept drawing MAX current when trying to recharge. Why the 30 amp 32 V. fuse did not melt and open up, I don't know.
