1. Using a single chip and special software achieve the intelligent control.

2. Using battery discharge rate characteristics modify the discharge control. Final discharge voltage is the control point modified by discharge curve to eliminate the inaccuracies by a simple over discharge voltage. In accord with inherent characteristics of the battery, different discharge rates has the different final discharge voltage to ensure the battery to be used effectively.

3. Over charge, over discharge, short circuit, overload protection, reverse polarity protection, reverse current protection at night, automatic control and so on; more protection from damaging any parts and burning insurance out.

4. Adopting series connected type PWM as the main circuit, the voltage loss of the charge loop lower nearly half compared with the circuit using the diode's charge reduced; in contrast to non-PWM, the charge efficiency is higher 3% - *6%; an increase of power utilization time; normal direct charging; automatically control of float charging make sure the system with long lifespan.

5. Accurate temperature compensation.

6. Intuitive LED indicates the current battery status to make sure that users understand the behavior in service.

7. Cancel set point adjustment and control of potentiometer, and use of Flash memory to record the work control points to set the digitization to eliminate the vibration due to deviation and reduce errors and reliable factors by drift and other control points.

8. Using of soft-touch keys is convenient and aesthetic.
