ABSTRACT This design is aimed at providing a system that has the capability of recharging batteries after use. The design is to incorporate an auto charging cut off circuit that operates when the battery is fully charged to avoid damaging the device and also a low voltage circuit which prevents the system from damage should in case the battery voltage level drops to a particular preset value. This design is used to charge batteries not exceeding 36volts and a lineup of batteries not exceeding 10 in number. The current supply of the charging system does not exceed 3amp per charging time.
