1.the controller use a MCU as the controlling core, so charging and discharging control stratey is more intelligent, charge and discharge control voltage more accurate, with battery low-voltage, over voltage, load over-current, short-circuit and other protective functions.

2.The controller use a red-green LED lamp to indicate the load state and load fault, There are four green LED to indicate the battery SOC and charging state.

4.The controller use 3 step charging controlling, It can improve the battery charging full and to extend the service life of the battery.

5.The controller with one USB power port (optional function).
