Suitable Applications

The SOK SK12V100PC is designed for compatible 12V deep-cycle energy storage applications, including RV house batteries, marine systems, solar power systems, off-grid installations, backup power, and other mobile or stationary battery banks. Its compact dimensions and 24.7 lb weight make it suitable for installations where available space and battery weight are important considerations.

Smart BMS & Cell Balancing

The integrated Battery Management System is designed to protect the battery during charging and discharging. The system includes overcharge, over-discharge, over-current, short-circuit, and temperature protection, while automatic cell balancing helps maintain consistent cell voltage.

Series & Parallel Configuration

Up to four compatible batteries can be connected in series for higher-voltage battery-bank configurations. Up to 10 compatible batteries can be connected in parallel for increased total capacity. Use batteries with matching specifications and follow the manufacturer's recommended wiring and installation procedures.

Charging & Operation

The recommended charging current is below 50A, while the maximum charge current is 70A. The recommended charge voltage is 13.8V–14.6V. The recommended low-voltage disconnect is 10.4V, with the BMS discharge cutoff specified above 10.4V and reconnect voltage above 11.6V.

Temperature & Enclosure

The specified charge, discharge, and storage temperature range is -4°F to 140°F (-20°C to 60°C). The sealed plastic enclosure has an IP65 rating for dust and water-jet protection. The battery should still be installed in accordance with the manufacturer's environmental and installation requirements.

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. Verify battery voltage, charger compatibility, cable sizing, terminal connections, and system requirements before installation. For series-connected batteries, use compatible batteries with matching specifications and follow the manufacturer's installation guidance.
