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

Ótimo módulo de proteção! Uso em meus projetos de carregador de baterias de lítio para drones. Funciona muito bem, protege contra sobrecarga e curto-circuito. A entrega foi rápida e o produto chegou bem embalado. Só não dou 5 estrelas porque demorou um pouco para chegar ao Brasil.

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!
