3S Battery Protection Board (BMS) 40A 12.6V - (AD66354)

Description:

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 functions for a battery pack.

Note: Connect strictly according to the wiring diagram 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit. When using a motor brush, try to connect a non-polar capacitor (withstanding voltage greater than 25V, capacity of 10uF-100uF) to the positive and negative terminals of the motor to prevent reverse spike from the motor.

Specifications:

- Continuous discharge current (upper limit): 40A (if the cooling environment is not good, reduce the load current)

- Continuous charging current (upper limit): 20A

- Charging voltage: 12.6 V - 13.0 V

- Nominal cell voltage of 3.6 V, 3.7 V lithium battery (including 18650, 26650, lithium polymer battery)

- Dimensions: 5 x 4.2 cm (improved version)
