4S 40A Active Enhanced Balancer 18650 Lithium Battery Board

Detailed Information About The Product:1. 4 series 16.8V 40A lithium battery protection board with own function - AUTO )2. Integrate 10 low-resistance MOS tubes with a continuous discharge of 40A, suitable for electric drills, sprayers, LED lights, and low-power inverters3. of application: Applicable to 4.2V lithium battery with nominal voltage of 3.7V and full voltage. It is suitable for electric drills with starting current 80A and power 230W.4. The high current heating is reduced by 30%, and the anti-interference function is increased5. Product weight: 9.3g; Charging voltage: 16.8~18.1v; Continuous discharge current upper limit): 40A if the heat dissipation environment is not good, reduce the load current); Continuous charging current upper limit): 20A Conditions for successfully starting the electric brick:1. 4 15C-20C power batteries or 810C-15C power batteries ordinary 18650 power drills are required!)2. The connection line between the battery pack and the protection board should be as short as possible and as thick as possible3. When welding the battery for the first time, do not need any load or any equipment at the output end.Precautions:1: 4 10C-20C power batteries, or 8 5C-10C power batteries are required to successfully the electric drill recommended power battery models: VTC4, VTC4A, VTC5A, VTC6) 0V and 12.6V connecting cables, use 3 square mm above copper wire sheet cannot be used!!)2: Strictly connect 0V, 4.2V, 8.4V, 12.6V, 16.8V according to the , do not touch any components on the board when soldering the wires, and do not intentionally short-circuit.3: When the battery is welded for the first time or is being , as long as a single battery exceeds the 4.2V430 resistance, it will heat up and discharge discharge to about 4.19V and stop heating). If the 430 resistor is seriously hot 't dare to touch it when it is too hot), check whether the wiring is wrongcolor:GreenMaterial:PCBsize:45 x 55 x 3.4mm Package Contents:1 x 4 string increase board Only the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real .
