I'm trying to set up an auxiliary battery for a winch, fridge, etc. Seems like there are a dizzying number of options for doing that. I'm not super skilled with electrical, so I go slow and careful. I have a couple of questions to start:
1. What is the best ground for the aux battery? Same ground on the engine as the starting battery?
2. Is it possible to overcharge and damage or fry a Deep cycle AGM battery with a normal voltage regulated alternator? My alternator puts out maybe 70 amps.
