I know there was a discussion on here fairly recently about having a 2nd Battery on a vehicle but my application is slight different.
I am spending alot of time working on the barn and so I don't have to have the generator running I am charging a battery on the van while driving about and then connecting it to an inverter at the barn, this just charges my cordless drill, my phone and powers a radio.
Currently I have a lead coming from the cigarette lighter socket going to the battery, luckily the socket gets disconnected automatically when I start the van so the fuse doesn't blow when I forget to pull the plug.
The plan is to wire in some Anderson plugs (with a fuse) so that I don't have to fiddle with the dodgy lighter socket connection but the problem I've found is if I leave the battery connected with the ignition off the fan and radio stay on!
I was going to stick a diode inline so that the battery doesn't backfeed the accessory circuit but I'm unsure of the wattage to use?
