Suitable Applications

The SOK SK12V206H is designed for compatible 12V deep-cycle applications including RV house batteries, marine systems, solar installations, off-grid power systems, backup power, and other mobile or stationary energy storage setups. Its 206Ah capacity and built-in heater make it suitable for systems that require high-capacity lithium storage and low-temperature charging support.

Bluetooth Battery Monitoring

The built-in Bluetooth 4.0 connection allows the battery to communicate with compatible iPhone and Android devices through the ABC-BMS application. Users can access available battery information and monitor operating status from a compatible smartphone.

Smart BMS & Protection

The integrated Smart Battery Management System provides protection against overcharging, over-discharging, over-current, short circuits, and high-temperature conditions. Low-temperature charging cutoff and automatic cell balancing are also included to support safe and consistent battery operation.

Built-In Heating

The SK12V206H includes an internal heater pad designed to support charging in cold conditions down to -4°F. Charging should remain within the battery manufacturer's specified temperature and current limits.

Series & Parallel Configuration

Up to four compatible batteries can be connected in series to create higher-voltage battery banks. Batteries can also be connected in parallel for increased capacity. When installing batteries in series, use batteries with matching specifications and state of charge, and follow the manufacturer's requirements for battery voltage balancing.

Serviceable Battery Design

The detachable cover provides access to internal components, including the BMS and battery cells. The design allows the BMS and cells to be replaced where compatible replacement components and service procedures are available.

Charging & Operation

The recommended charging current is 40A, with a maximum charging current of 70A. The recommended charging voltage is 14.6V. Use a compatible 12V LiFePO4 charger and verify charger voltage, current, polarity, wiring, and battery temperature before charging.

Important Usage Note

Actual battery performance and service life depend on charging settings, discharge rate, depth of discharge, temperature, connected equipment, wiring, and installation conditions. Do not exceed the specified charge or discharge limits. For series-connected batteries, ensure compatible batteries are at the same state of charge before connection and use the required voltage-balancing equipment. The IP50 enclosure is intended for protected environments and should be kept away from rain, standing water, and direct moisture exposure.
