Looking at adding a separate 12 volt battery for my added electronics/NEMA. Currently run the electronics via a dedicated line to the fuse block under the console from my starting battery. Should I get a battery switch that allows me to turn everything off, just the electronics on, just the starting motor on, and all on ? Do they make such an animal ?
Also if I get a 12 v deep cycle battery and the starting battery is low, can I start the motor via the deep cycle ?
