Suitable Applications

The SOK SK12V280H is designed for compatible 12V deep-cycle applications including RV house batteries, marine systems, solar energy storage, off-grid power systems, backup power, and other mobile or stationary energy-storage installations. Its 280Ah capacity provides a high-capacity solution for systems requiring extended battery runtime.

Bluetooth Monitoring

The built-in Bluetooth 4.0 functionality allows users to connect the battery to a compatible iPhone or Android smartphone through the ABC-BMS application. The app can be used to monitor available battery information and operating status without requiring a separate external battery monitor.

Smart BMS Protection

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

Built-In Heater

The SK12V280H includes an internal heater pad designed to support charging in low-temperature environments. The heater works with the battery's temperature-management system to help maintain suitable cell conditions during cold-weather operation.

Series & Parallel Configuration

Up to four compatible batteries can be connected in series for higher-voltage battery-bank configurations. Multiple batteries can also be connected in parallel to increase total amp-hour capacity, with the supplied specifications allowing up to 10 batteries in parallel.
