Key Features

1. Built-In Heating Element

Automatically activates in low temperatures, preventing the battery from freezing and maintaining optimal internal chemistry. This allows for efficient charging and discharging even at -20°C (-4°F), where conventional batteries fail.

2. Exceptional Cold Weather Performance

Goes beyond standard "low-temperature" claims. The heating function guarantees your solar lights will continue to work through the harshest winters, providing uninterrupted illumination from dusk till dawn.

3. High Capacity & Long Runtime

With a robust 45Ah capacity, this battery stores more solar energy during the day, powering your lights for longer hours at night. Perfect for security lights, garden lamps, and pathway lighting.

4. Superior LiFePO4 Technology

Offers exceptional safety (no risk of fire), a long lifespan of over 2000 cycles, and stable 12.8V output. It outperforms and outlasts traditional lithium-ion and lead-acid batteries.

5. Maintenance-Free & Ready to Use

A complete, drop-in solution. Simply install it into your compatible solar light system and enjoy reliable, worry-free power for seasons to come.
