A BMS is a battery management system often used in a medium or large format lithium-ion battery pack. A BMS is a circuit board that provides protection, monitoring, balancing, and other high-level functionality for a battery pack.
Specifications
Continuous discharge current (upper limit): 4A (if the cooling environment is not good, please reduce the load current use)
Charging voltage: 9v - 12v
Nominal voltage cell of 3.6V, 3.7V lithium battery (including 18650,26650, polymer lithium battery)
Dimensions: 35mm x 18mm
Note:
Connect strictly according to map wiring
When a motor brush is used, try to connect a non-polar capacitor (withstand voltage above 25v, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor.
