tiempo de entrega excelente terminado y aspecto del producto muy profesional ideal para mis proyectos de fuentes con baterías litio

Conforme aux indications. Manque de précision au niveaux des connections. Il faut bien prendre en compte les 2 schémas disponibles dans la description du produit. Il permettrait de faire du 4 et 5S. A vérifier lors de tests. Complies with indications. Lack of precision in connection. Please take into account the 2 diagrams available in the product description. It would make 4 and 5S. To be checked during tests.

I ordered 3 of these boards and none of them worked. They would not charge the batteries. There are no Leds indicating what is happening. Dissatisfied.

Tutto OK.

all right
