OptiMate™ 20 W Solar DUO Charger/Maintainer is the smart, 24/7 battery care solution powered by the sun ☀️🔋.

The system pairs a 20 W high-efficiency solar panel with a 12 V controller that converts low solar input into high-current pulses for more effective charging and maintenance of 12 V batteries, including 12.8 V/13.2 V lithium (LiFePO4/LFP) and lead-acid STD, AGM and gel chemistries.

The charger supports a low-volt start down to 1 V and features a smart charge controller that automatically adjusts the charge routine based on battery type and condition. A 14' cable separates the charger from the panel for flexible placement and optional extension.

Designed to withstand cold conditions down to -4°F.

Travel kit includes:

  • travel bag
  • polycrystalline solar panel with adjustable stand
  • OptiMate solar DUO controller
  • battery clips
  • battery lead
  • weatherproof charge controller case
  • mounting suction cups (additional cups sold separately)
