With the typical Perko Battery switches can you hook up 3 batteries or just 2?
I would like to have #1 on the switch for my starting battery, and have #2 on the switch for two deep cycles daisy chained together for my JL Audio system.
Or what is the best way to set up a starting battery and 2 deep cycles for the sound system- how would all three get charged while underway.
Thanksi
