Description:This item is equipped to avoid overcharge, over release, short circuit, over loading and solar battery inversely connecting. It use the battery discharge rate characteristics to correct discharge control. And it adopts PWM main charging circuit of tandem type to effectively improve charging efficiency. The LED indicator shows the batteries current situation to make the customer get the information of the batteries. Three operating modes can be selected: normally open mode, the pure light control mode and light control plus timing mode.Features:Equipped with device to avoid overcharge, over release, short circuit, over loading and solar battery inversely connecting.
