Products Description

3S 20A 11.1V 12V 12.6V BMS Module Li-ion Lithium Battery 18650 Charger PCB Protection Board

3 strings of 12.6V lithium battery protection boards
Application: Nominal voltage 3.6V, 3.7V lithium battery (including 18650, 26650, polymer lithium battery)
Product size: 50*16.5*3mm
Product weight: 2.4g
Charging voltage: 12.6V-13.6V
Continuous discharge current (upper limit) : 10A (If the heat dissipation environment is not good, please reduce the load current)
Continuous charging current (upper limit) : 5A

Note: The PCB baseboards of 5A and 10A are the same, the difference is that 5A has 2 MOS tubes and 10A has 4 MOS tubes.

Note 1: Connect 0V, 4.2V, 8.4V, 12.6V strictly according to the drawing (0V or 12.6V is connected to the wrong burning plate, 4.2V or 8.4V is connected to the wrong plate and does not work).

Note 2: When there is a load of brush motor, a non-polar capacitor (25V +, 10uF-100uF) must be connected in parallel to the positive and negative terminals of the motor to prevent the reverse peak voltage generated by the motor from interfering with the protection plate or breakdown of the MOS tube.

Note 3: When connecting three groups of batteries in series, please ensure that the voltage of each group is the same. If not, please fill each group of batteries separately and then use them in series... In the discharge test, the group of batteries with a faster voltage drop is the differential battery. For some customers with a poor electronic basis: do not mix good batteries and bad batteries together! The closer the capacity/internal resistance of the three batteries, the better! (2 good batteries +1 bad battery =3 bad batteries).

DIY のモバイルバッテリー用に購入しました。5V 昇圧モジュールとしてとても使いやすいです。LED ディスプレイで充電状況が一目でわかるのが便利です。ただ、少し発熱が気になりますが、使用上は問題ありません。

Die BMS Platine funktioniert einwandfrei! Ich habe sie in einem 3S Li-Ion Akku-Pack für mein E-Bike verbaut. Der Schutz vor Überladung und Tiefentladung funktioniert zuverlässig. Die Verarbeitung ist sehr gut, alles sieht stabil aus. Würde ich wieder kaufen!

This BMS board with balancing is a game-changer for my 18650 battery pack build. The cell balancing works flawlessly, keeping all three cells at the same voltage. It’s compact, easy to solder, and the 25A rating is perfect for my portable power station. Couldn’t be happier!
