No outlet where the bike is parked? The OptiMate Solar DUO 20W kit keeps a 12V battery charged and maintained with free power from the sun. The 20W panel goes where the sun is, and the smart OptiMate Solar DUO controller sits by the battery, converting low solar power into high-current pulses that charge and maintain more effectively than a panel wired straight to the battery.
It adapts automatically to lead-acid (STD, AGM, GEL) or 12.8V/13.2V LiFePO4 lithium batteries, charges and maintains by day, monitors by night with almost no draw, and shows charge level on its LEDs. It's a maintainer first: a solar panel keeps a healthy battery topped up, while a plug-in charger will bring a badly run-down battery back much faster. Lithium support is for 4-cell LiFePO4 batteries only.
