Introduction

The charge and discharge protection module or BMS (Battery Management System) modules are designed to charge four 18650Lithium – Ion/Polymer batteries in series with a maximum current of 20A with protection against adverse conditions such as overcharge and overdischarge, overcurrent and short circuit.
The 4-cell lithium battery charge protection module with a maximum current of 20A is suitable for 4-cell (4S) lithium batteries, which are commonly used in various applications including emergency power systems, electric tools, electric scooters and solar energy systems.
These modules are usually categorized based on the current rating and the number of battery cells they support. This model is capable of supporting a 4-cell battery with a current rating of 20A.

Specifications

Cell configuration: Supports 4 18650 size lithium-ion or lithium polymer battery cells in series (4S)
Operating voltage: 14.8V (Nominal voltage)
Full charge voltage: 16.8V (maximum voltage)
Maximum charge and discharge current: 20A
Dimensions: 60×34 mm

Application

The four-cell battery management module (BMS) with a capacity of 20A includes multiple protection features such as: preventing charging above 4.25V to 4.3V, discharging below 2.5V to 2.7V, overcurrent, short circuit and high temperature.
These features ensure that the battery life is extended and dangerous conditions such as fire and explosion are prevented by preventing overcharging and overdischarging.
Also, this module is used in quadcopters, drones, portable power banks, solar energy systems, emergency backup power, medical devices and … due to its increased battery efficiency with optimal energy management.
