grab a multimeter for 20 bucks. I checked my engine alt output while running, it should be 14.2-14.4 but do check your specific engine alt output, and at the batter(ies). should be a small drop due to resistance. all while running. Next turn off the engine, trim motor up/down, check batts at rest you want to see what that is as well. As well, when at rest (no engine) check the voltage drop at the engine compared to batts. I think I see .2 volts drop which indicates a hell of a good good wiring job and big cables.
Prob good ida to clean all batt connects every couple of months. I used di-electric grease as well, never use wingnuts, use locking nuts on batt connections and posts.

-this info came from another site on batteries.
I upgraded to a BEP cluster from a Perko switch, for voltage regulation and isolation. Considered some different approaches-this was the simplest and cleanest.
With above tests you can at least nail down where a problem may lie by PoE
