Tecmate TM523-6TK OptiMate Solar 60W Travel Kit 6-Step 12V 5A Solar Battery Charger & Maintainer

The Tecmate OptiMate Solar 60W Travel Kit (TM523-6TK) is a fully automatic, sun-powered 12V battery charger and maintainer designed for lead-acid batteries in motorcycles, powersports vehicles, automobiles, and more. Functioning as a charger by day and a monitor by night, this kit provides 24/7 battery protection without requiring an AC power source.

The TM523 charge controller pairs with a 60W polycrystalline solar panel to deliver up to 12V / 5A of output. Its 6-step smart charging program automatically adjusts charge delivery — selecting pulse or continuous charge based on available sunlight — to safely bring batteries to full charge and keep them there. The controller is housed separately from the panel, allowing it to be placed close to the battery for easy monitoring while the panel is angled toward the sun. The cable reach between panel and controller is 124 inches (315 cm).

Key Features:

• Saves deeply discharged batteries from as low as 1V using unique pulse recovery action
• Smart charge control selects pulse or continuous charge based on sunlight strength for fastest possible charge
• Intelligent overnight maintenance — if the battery holds charge overnight, maintenance continues; otherwise the program reverts to the OPTIMIZE step
• Battery state-of-charge displayed every 3 seconds via LED indicator
• Draws less than 0.5mA in monitor mode — safe for long-term, unattended connection
• Automatically switches to CHARGE mode when sufficient solar power is available
• Weatherproof charge controller — suitable for indoor and outdoor use down to -4°F (-20°C)
• Fully safe for vehicle electronics: spark-suppressed, no overcharge risk, automatic shutdown if short-circuited or battery disconnected
• Compatible with 12V Flooded STD, EFB, Sealed AGM-MF, GEL, and Cyclic Cell lead-acid batteries from 2–240Ah
• Adjustable rear stand angles the panel for maximum solar energy capture
• Four anchor points accept standard ground pegs/stakes for outdoor use
