A hard shield for the back side of your battery. Stops mud and other debris from hitting the backside of the battery and possible spraying up into the controller area.
Phase cut out explanation:
if you run your motor wires through the back side of your frame you will need a cut out in the guard. Depending on where the wires want to go is how you decide which cut out to get. If you don’t run your motor wires through the frame where the guard goes then select no cut out.
