Products Description
3S 40A BMS Board 11.1V 12.6V 18650 lithium battery protection board for Drill 40A Current Lipo Cell Module
3s 12.6V 40A lithium battery protection board:
Scope of application: It is suitable for lithium batteries with a nominal voltage of 3.7V and a full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, and no size restrictions) Product size: 41*55*3.4mm (enhanced version), 41*60*3.4mm (balanced version) Product weight: 8.8g (enhanced version), 9.8g (balanced version) Charging voltage: 12.6V~13.6V Continuous discharge current (upper limit): 40A (If the heat dissipation environment is not good, please reduce the load current to use) Continuous charging current (upper limit): 20A Enhanced version: suitable for electric drills with starting current below 80A and power below 170W. Balanced version: It is suitable for electric drills with starting current below 80A and power below 170W, with equalizing charging function.
Note 1: To successfully start the electric drill, you need 3pcs 10C-20C power batteries, or 6pcs 5C-10C power batteries, 0V and 12.6V connecting wires, and use copper wires of more than 3 square millimeters (no nickel sheets!! ). Note 2: Wiring 0V, 4.2V, 8.4V, 12.6V strictly in accordance with the diagram, do not touch any components on the board when welding the wire, and do not intentionally short-circuit. Note 3: When the battery is welded for the first time or is being charged, as long as a single battery exceeds 4.2V, the 430 resistance will heat up and discharge (discharge to about 4.19V to stop heating). If the 430 resistor is very hot (you can't touch it when it is too hot), please check whether it is connected to the wrong wire.
