More or less they are a check valve. Thing is you will need to get something made to handle high currnet and voltage. Most diodes won't. You will overcome it's resistance to the flow of electrons then poof. Factory Installed smoke..

Ensure you have one capable of handling the voltages and currents you are expecting plus a generous amount over and above that for spikes of current etc.

How do you plan on wiring it in?
