PartNumber: 4S-Li-ion

Details: NOTE: 1) This board is not suitable high power electronic tools, like screwdrier and drill. 2) Above 3A device,means the battery discharge rate is more than 3C. 1C rated battery, 2000mah equals 2ah*1=2A max working current. 3C rated battery means 2ahx3=6A Max working current. Features: 1) High-accuracy voltage detection circuit; 2) Terminal of the charger using high voltage device; 3) Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit); 4) MOS transistor can control the battery charge and discharge; 5) low standby current consumption. 4S LI-ION BMS Parameters: Over Charge Voltage:4.25-4.35v±0.05v Over Discharge Voltage: 2.3-3.0v±0.05v Max working current:10A Max Peak current:20A Working Temperature:-40---+50 Storage Temperature:-40-- +80 Small current:6uA Life cycle:50000hours Resistance:45mΩ Short cut Protection: yes ,change for repair Size:35*35*3.0mm BMS solder instruction: B+ connected battery positive; B1 the connect point between battery 1 and battery 2 B2 connect the point between battery2 and battery 3 B3 Connect the point between battery 3 and battery 4 B- connect to battery negative end P- + connection charge / discharge positive; P- connection charge / discharge negative 4S Li-ion18650,LiCoO2,LiMn2O4,Li(NiCoMn)O2 rechargeable batteries 4S Lipo rechargeable batteries
