## Description

MONITOR 127 LITHIUM BATTERY SAE SOCKET

Review: Exactly what I needed. Took all of 3 minutes to install and makes keeping the batter charged super easy. Pull up in the garage and just plug it in. When I'm ready to go I just unplug it and let it hang under the seat, just inside the frame. The build quality is far better than I expected for the price and the colored lights letting you know the status are a nice touch.
