TECMATE Charger Solar Duo 10 Watt TM522-D1

If you're storing a race vehicle, seasonal bike, or backup motorcraft between events, a dead battery is an unnecessary headache. The TECMATE Charger Solar Duo 10W keeps your 12V battery topped up and healthy without drawing power from the grid—especially valuable when your rig sits in a garage or outdoor storage for weeks at a time. This modular system combines a weatherproof solar panel with an intelligent charge controller that actively maintains battery health during the day and monitors state of charge every 3 seconds at night, so you'll never guess whether your battery is ready when you are.
