Specifications
| Model | 3S 40A Enhanced |
| Brand | Unbranded |
| Country/Region Of Manufacture | China |
| Type | BMS Protection Board |
Enhanced: suitable for electric drills with starting current below 80A and power below 135W. Balanced: suitable for electric drills with starting current below 80A and power below 135W. Note 1: Successfully starting the electric drill requires 4 15C-20C power batteries, or 8 10C-15C power batteries (ordinary 18650 cannot start the electric drill). Note 2: Strictly connect 0V, 4.2V, 8.4V, 12.6V, 16.8V according to the diagram, do not intentionally short-circuit. Note 3: When there is a load with a brush motor, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) in parallel with the positive and negative terminals of the motor to prevent the reverse peak voltage generated by the motor from interfering with the protection board or Break down the MOS tube.
