Features When the battery voltage rises to a set value, the module automatically switches the load back on and stops charging the battery. This is a low voltage switch module used to automatically turn off the load when the voltage drops below a set value. Both the off and the inrush voltage value can be adjusted by simply adjusting the potentiometer. This control board helps you save energy and extend battery life. Then it will automatically connect to the charger to charge the battery. Designed with an LED indicator to indicate whether the load is off or on. Specifications: Suitable battery voltage: 12 V. Voltage error: ±0.1V Load current: 10 A. Size: 6 x 3 x 1.8 cm / 2.4 x 1.2 x 0.7 inches. Weight: 24g (approx.) Features: Then it will automatically connect to the charger to charge the battery.
