I am a cub scout adult leader and we are wanting to hook up a battery in our 14 foot enclosed trailer to run some interior lights for when we are camping so we can see in the trailer. I am wanting to have it charged from the vehicles parking lights at a lower amp, but not have it back feeding back into the vehicle. Has anyone done this before ? What type of diode do I need to do this or what would I need to do this...
