The regen thing is apparently in new vehicles as described in the Sterling DC-Dc link. It says that makes the alternator voltage drop to 12.x and jump to 15.x at times as you drive.

So that jump to 15.x would harm your House battery by over-voltage if you have a House battery vulnerable to that. (Li say)

I don't know if that is just in cars or also in motor homes. I don't know if it is in all new vehicles that can tow a trailer that would affect that trailer's battery.

Seems kind of serious to me. ?
