The CM Series is an economic solution for preventing battery overcharging in low-power systems. It is simple, compact and easy to use and install. CM Series features a 2-stage PWM charging algorithm that supplies an even charge across all battery cells which lengthens battery lifespan. One green LED states when the CM controller is charging and reducing current via PWM.
