This is the casing for the SOLAR 18650 CHARGE CONTROLLER.
Originally devised for the SOLAR TRACKER (Rig and Controller), it is fairly generic and will be used for the upcoming CYCLING HELMET SOLAR PANELS.
Included are face-plate/labels for onboard switch or a breakout for a remote switch. The controller screws directly onto the battery holder, minimizing the footprint and lead lengths.
