Todo perfecto.
J'ai commandé une batterie sanfou 50ah et un chargeur. Produits reçus si rapidement. J’ai été très satisfait de leur équipe d’expédition et d’assistance ! Je n'ai jamais eu l'occasion d'utiliser la batterie auparavant, mais j'ai hâte de mettre mon bébé dans la petite voiture et de voir comment elle résiste ! Jusqu'à présent, je recommanderais cette entreprise !
