14.8V 18650 lithium battery protection board 4 strings 16.8V20A current limit protection 4 series 18650 battery 16.8V 16V 14.8V： 14.8V (Li-ion 18650 or li-ion battery rated voltage)16.8V (Li-ion battery full charge voltage)14.4V ( Lipo battery pack rated voltage) Properties:Overcharge voltage range: 4.25-4.35v±0.05vOverdischarge voltage range: 2.3-3.0v±0.05vUpper working current: 10AOperating temperature: -40-- +50℃Upper limit instant current: 20AStorage condition: -40-- +80℃Static current: less than 30uAEffective life: more than 50,000 hoursInternal resistance: less than 100mΩShort-circuit protection: It can be protected and needs to be charged for recoveryCharging voltage 16.8V-17VSize: 35*35*3.6mm 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. NOTE:1) this board is not suit high power electronic tools, if use for screwdrier and drill, please don't buy.2)Above 3A device,means the battry 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.
