Each route monolithic integrated circuit independent control,may realize the sufficient electric disch arge function,also may realize the automatic minutestage sufficient lectric discharge,even may achieve the simple minute accommodates function;Battery series charge,electric current realtime sampling;The digital tube demonstrated that,artistic is striking,sufficiently discharges the condition demonstration magnitude of current,the stopped state then the demon stration voltage value,may monitor the battery contact condition;The magnitude of current numerical code establishment,simple is practical.Applies in battery the and so on lithium polymer,lithium ion precharge, turns into.
