• Utilization of a single chip microcomputer and special software to achieve intelligent control
• Use of a highly accurate battery discharge rate for discharge control. The voltage at the end of discharge is the controlled point of the discharge rate curve after correction, which eliminates the inaccuracy caused by the simple over discharge of voltage control, thus conforming to inherent battery characteristics. Different discharge rates feature different end voltages.
