Maintenance-free battery charger

Main features：

1、The voltmeter displays charging parameters such as voltage, current, capacity and time. 

2. The digital tube displays charging parameters such as voltage, current, capacity and time. 

3. The microprocessor continuously monitors the charging current and the rate of voltage change, and automatically adjusts the charging curve. 

4. Temperature compensation function for the charging constant voltage point; 

5. It offers multiple control methods including charge quantity, time, and capacity. When the charge is sufficient, it automatically switches to trickle charging mode to protect the battery and extend its lifespan. 

6. After sufficient charging, the device will automatically cycle and replenish the power. 

7. Automatic equalization charging function, ensuring the consistency of individual cell capacities of the battery pack; 

8. Automatic initial charging function; 

9. Power-off memory automatically starts up; 

10. Automatic detection and delayed soft-start function; 

11. Strong protection functions such as open circuit, reverse connection, overload and overheating;
