3S 12.6V 18650 lithium Battery Protection Board (BMS) Balanced Version 40A current
৳190
৳145
SKU : MK0044
Specification
Description
- Scope of application: Suitable for lithium batteries with a nominal voltage of 3.7V and a fully charged voltage of 4.2V (including 18650, 26650, polymer lithium batteries, without any limitations on external dimensions)
- Product size: 41 * 55 * 3.4mm (enhanced version)
- Product weight: 8.8g (enhanced version)
- Charging voltage: 12.6V -13.6V
- Continuous discharge current (upper limit): 40A (If the cooling environment is not good, please reduce the load current for use)
- Continuous charging current (upper limit): 20A
- Enhanced version: suitable for electric drills with starting current below 80A and power below 130W.
- Attention 1: Successfully starting the drill requires 3 15C-20C power batteries or 6 10C-15C power batteries (regular 18650 cannot start the drill!!); 0V and 12.6V connecting wires, use copper wires with a size of 3 square millimeters or more (nickel sheets cannot be used!!!).
- Attention 2: Strictly follow the wiring diagram for 0V, 4.2V, 8.4V, and 12.6V, and do not intentionally short circuit.
- Note 3: When charging the battery, it is normal for the "430" resistor to generate heat, indicating that the equalization circuit is working; If the "430" resistor also heats up without charging, please check if it is connected incorrectly.
- For some customers with poor electronic foundation, please note: never mix good batteries with poor batteries! The closer the capacity/internal resistance of 3 sets of batteries, the better! (2 good batteries+1 poor battery usage effect=3 poor battery usage effect).
