How do I extend the time that I can use the 110 outlet or watch tv while the engine isn't running?

Asked by Christopher Sep 10, 2017 at 02:29 PM about the 2009 Chevrolet Express 1500 LT RWD

Question type: Car Customization

I ran a hot wire from my starter battery to a fuse to a smart solenoid to a fuse to
another battery.  When the engine is running the solenoid connects the
batteries so they both charge but that would mean that when just in accessory
they are not connected and it's not doing me any good cause I'm just draining
the starter battery.

Thats what I'm trying to do but I think everything runs off the one battery so I'm just trying to back up the main.

If you have the room adding a battery is easy. Just wire them in parallel so that you have 12 volts instead of 24. The inverter should be attached to the accessory battery(s).
