Charge Controllers

Charge controller,charge regulator or battery regulator limits the rate at which electric currents added to or drawn from batteries.It prevents overcharging and may prevent against overvoltage,which can reduce battery performance or lifespan, and may pose a safety risk. It may also prevent completely draining ("deep discharging") a battery, or perform controlled discharges, depending on the battery technology, to protect battery life.The terms "charge controller" or "charge regulator" may refer to either a stand-alone device, or to control circuitry integrated within a battery pack, battery-powered device, or battery recharger.
