2S BMS 7.4V-20A
BMS (Battery Management System) – a battery management system that is designed to monitor the status of batteries, control the process of charging/discharging the battery, etc.
- Small size designed for a four-cell battery pack.
- Simple and convenient circuit for easy connections
- Over-charge/Over-discharge Protection.
3S BMS-25A
Applicable to the following products (within rated power):
Electric drill, 775 motors (6A-10A), small power inverter, small power vacuum massager battery, LED lamp, 12V standby power electronic products, 12V120W car washing pump, battery, solar street lamp monitoring standby power supply, and other products.
Rated current can’t over 25A, it can’t exceed 50A per 0.5 seconds.
3S BMS-40A
- 3S 11.1V 12.6V 40A 18650 lithium battery protection board (comes with recovery function-AUTO Recovery).
- Application: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650.26650, a polymer lithium battery).
- Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the load current use).
- Continuous charge current (upper limit): 20A.
- Suitable for the drills with starting current below 80A, power 135W below.
Note:
- The Successful start of the drill requires a three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 cannot start the drill!!).
- Strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, 16.8V, do not deliberately short circuit.
- When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above25V, capacity 10uF-100uF) to the motor’s positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube.
