• 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.
• With overcharge, over discharge, electronic short out, overload protection, unique battery-reverse protection and other automatic control; The above protection does not damage any parts and does not burn the fuse.
• With the use of a serial PWM charging main circuit, the voltage loss of the charging circuit is reduced by about half compared with that of diode charging circuit, and the charging efficiency is 3% to 6% higher than that of non-PWM, which increases the consumption time. Lifting charge of over discharge recovery: the normal automatic control of direct/float charging gives the system a longer service life, as well as a high precision temperature compensation.
• All controls are industrial grade chips, which operate normally in hot, cold, and wet environments.

• Use a single chip microcomputer and special program for intelligent automatic control
