1. With full automatic control such as overcharge, over-discharge, electronic short circuit, overload protection, unique anti-reverse connection protection
2. Adopts series PWM charging main circuit, which reduces the voltage loss of the charging circuit by nearly half compared with the charging circuit using diodes, and the charging efficiency is higher than that of non-PWM 3%-6% higher, increasing the battery life; the over-discharge recovery charging, normal direct charging, and floating charge automatic control mode make the system have a longer service life; it also has high-precision temperature compensation

4. Overvoltage protection: 17V; ×2/24V
5. Overload and short-circuit protection: 1.25 times the rated current for 60 seconds, 1.5 times the rated current for 5 seconds when the overload protection is activated, ≥3 times the rated current when the short-circuit protection is activated
6. Total rated charging current: 10A
7. Float charge: 13.6V; ×2/24V; (maintenance time: until the charging return voltage is reduced)
8. Control mode: charging is PWM Pulse Width Modulation

Controller Main Functions:
