Re: Dual Battery Installation Write-Up - Pics

Sorry FJVP you are a little off the money there.

Wire the batteries in series will double the voltage, just like batteries in a flashlight. But wire the battery in parrallel and you keep the voltage the same and double the amperage capacity of the battery system. This would be similar to when you jump start a car.

What you would want to do is tie the negative to the negative, positive to the positive. Gains you lots of added capacity however there would be no back up like in the other systems. You will be draining both batteries at the same time, but it is the simpliest wiring and no solenoid is required.
I stand corrected, I did not specify in series vs parrallel. Thanks for the correction.
