does anyone know if I can use my 20 volt DeWalt batteries to power 12 volt appliances in my trailer. Mostly looking at led lights and low voltage things. I see an adapter than can be purchased but all it is, is a unit that you connect your 20 volt batteries to and have 2 wires running out of it. (see below). What about using an invertor
