Avant d'acheter vous devez vous assurez du courant maximum que le convertissuer peut supporter. La batterie originale sur ma bicyclette électrique est de 15AH, le convertisseur peut supporter jusqu'à 40 Ampères je peux donc ajouter une deuxième batterie d'un maximum de 25AH. Vous devez également vous assurer du type de connecteurs sur votre bicyclette et le convertisseur. Le connecteur nécessaire pour ma bicyclette et le convertisseur sont des connecteurs de type XT60. Le tout fonctionne à la merveille.
