I'm planning on reinstalling both batteries like I had last year. The way I did it last year was the "house" battery was only connected to the stereo and amp and it wasn't connected to the engine. I threw it on the battery charger at home. This year I'd like them both to be able to be charged by the engine. Here's my set up:
Starter Battery:
Marine Starting (24 Series)
625 CA
500 CCA
"House" Battery":
Dual Purpose (Starting / Deep Cycle)
875 CA
205 Reserve Capacity
**Goal**
Engine always charges batteries individually when the engine is running with priority to the starting battery. When engine is off the drain is always on the "house" battery, or never drains the starting battery below a certain level.
I've started reading about battery switches, relays, voltage sensing switches and voltage sensing relays. It kind of sounds like I should use a switch and VSR, but I'm not sure.
Can anyone provide some feedback or share your setup?
