2S Battery Protection Board (BMS) 4A 8.4V - (AD85747)

Description:

A BMS is a battery management system that is 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 0V, 4.2V, 8.4V map wiring; do not deliberately short circuit. When using a brush motor, try to connect a non-polar capacitor (withstanding voltage greater than 25V, capacity from 10uF to 100uF) to the positive and negative terminals of the motor to prevent the motor's reverse spike.

Specifications:

- Continuous discharge current (upper limit): 4A (if the cooling environment is not good, please reduce the load current usage)

- Continuous charge current (upper limit): 2A

- Charging voltage: 8.4 V - 9.0 V

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

- Dimensions: 35 x 18 mm (upgraded version)
