    Pros:
    J'aime bien l'affichage de chargement des batteries qui ne sont pas fournies. J'ai ajouté des batteries de 9600 Ah. Tout va bien pour le moment. Pour insérer les Batteries, il suffit de faire coulisser la coque supérieure. Rien e plus facile. I like the display of charging batteries that are not provided. I added 9600 Ah batteries. All is well for the moment. To insert the Batteries, simply slide the upper shell. Nothing easier.
    Cons:
    Batteries non fournies mais cela est spécifié dans l'annonce du produit Batteries not supplied but this is specified in product announcement
