    Product Description

    2S 20A BMS Charger 18650 Lithium Li-ion Battery Balance Protection Board


    2S 20A BMS Charger (Battery Management System) is a crucial component in the efficient and safe operation of battery packs. Designed to monitor the status of batteries, control the process of charging/discharging the battery, and provide protection against various electrical faults, the BMS plays a vital role in ensuring the longevity and reliability of battery systems. The EK-B2S20AM charge-discharge controller module, offered by Enerkey BMS, is a versatile solution for managing two 18650 batteries simultaneously. Equipped with protection against short circuit, overcharge, and over-discharge, this module offers a reliable and safe platform for battery management. Its compact design and robust features make it suitable for a wide range of applications.


    One of the key functions of the EK-B2S20AM charge-discharge controller module is to regulate the power supply for the batteries, ensuring that the maximum capacity of at least one battery is not exceeded. This not only safeguards the batteries from potential damage but also contributes to overall system efficiency. With a design life of more than 30,000 hours, this BMS controller promises long-term performance and reliability. The module features five pins, each serving a specific purpose in the battery management process. The B+ and B- pins correspond to the battery positive and negative poles, while the BM pin represents the mid-point of a battery assembly. The P- and P+ pins are dedicated to the negative charge/discharge terminal and positive charge/discharge terminal, respectively, enabling seamless integration with external circuitry.

    Wiring precautions:
    1. Installing the protective board requires a certain amount of technical electronic knowledge.
    2. When wiring, first connect the B- wire at the soldering pad position to the total negative terminal of the battery (the B- wire should be soldered to a short and thick wire) and solder the wired terminal to the battery pack first, and then insert the protective plate.
    3. The connection between the battery terminal B- and the protection board terminal B- should be short and thick, otherwise it will cause the protection board to charge and discharge in advance and malfunction.

    4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
