The SOK SK12V206H is the latest V8 version Bluetooth BMS battery, equipped with advanced balancing capabilities and integrated heating for reliable cold-weather performance. Engineered for off-grid systems, RVs, marine, and backup power setups, this battery features Bluetooth connectivity and a built-in heater pad, allowing safe charging even in temperatures as low as -20°C (-4°F).

The heater draws power directly from the charger—not from the battery cells—ensuring zero energy loss from the battery itself.

You can monitor the battery’s status via Bluetooth using the free ABC-BMS app available for iOS and Android.

Note: The State of Charge (SOC) may display incorrectly on initial use. Allow two full charge/discharge cycles for accurate calibration.
