Sell 3S 4S 5S lithium ion lithium battery 18650 charger BMS 25A 30A 40A 60A 100A balance belt protection board best price

3S 25A 12.6V Balance 11.1V (Li-ion 18650 or li-ion battery rated voltage) 12.6V (Li-ion battery full charge voltage) 10.8V (Lipo battery pack rated voltage) The lithium battery protection board is not included in the welding tabs. BMS activation method: use 12.6V Li-ion charger to charge. Note: 1) This board is not suitable for high power electronic tools, if you use it for screwdrier and drill, make electric bike series, fishing machine and 1W LED, please don't buy it. 2) Above 3A device means that the battry discharge rate is more than 3C. 1C rated battery, 2000mah equals 2ah * 1 = 2A maximum working current. 3C rated battery means 2ahx3 = 6A maximum working current. Balancer is only an auxiliary function, when balancing, battery charge, each series battery need with the same voltage. When a cell voltage is 4.2V, the first cell will not discharge to wait for other cells whose voltage rises to the same level. Note: Battery internal resistance differences within 5 milliohm, voltage within 0.03 V voltage, capacity varies within 50 ma Specifications: 1) high accuracy voltage detection circuit; 2) terminal of the charger using high voltage device; 3) built-in three-stage overcurrent detection circuit (overcurrent 1, overcurrent 2 or load short circuit); 4) You can control the MOS transistor battery charge and discharge; 5) low standby current consumption. Short parameter: Overcharge voltage: 4.25-4.35v Yes. 0.05v Over discharge voltage: 2.3-3.0v Yes. 0.05v Maximum working current: 25A Maximum peak current: 35-40A Working temperature: -40 --- + 50 Storage temperature: -40- + 80 Small current: 50uA Life cycle: more then 30000 hours Resistance: less than 100mOh. Short cut: can be maintained, charge can repair Size: 56 * 45 * 4.0mm 3S 40A 12.6 Balance Application: Rated voltage of 3.6V, 3.7V lithium battery (including 18650.26650, polymer lithium battery). Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the use of load current). 5S 100A 21V LMO 1.
