Sehr gutes Lademodul! Doppelanschlüsse funktionieren stabil, perfekter Überladeschutz für 18650 Batterien. Einfach zu löten und installieren, sehr zufrieden.

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!
