Does anyone know of a “battery guard” or “voltage guard” type product that can be installed under the hood, right at the battery?

I want all battery-draining accessories cut off when the battery voltage drains, leaving me enough power to start the truck. I recently had a sleeper installed on my truck with lights and a small fan in the ceiling. If I fall asleep with the fan and light on there is not enough power to start the truck in the morning.

I am not interested in battery guards that plug into the cigarette lighter.

Thanks.

If you still need one, I have used several from www.galls.com. Both of my boats have them and they hold up well. Hope this helps.

Here is a direct link to this product. It sounds like it would work. If anyone has tried it, let us know. I'll let you know if I get one.
