If your e-bike battery is a compatible 36V lithium battery system, the original charger output is 42V, and the battery supports a 4A charging current, this charger may be suitable. In addition, the connector shape, pin configuration, and polarity should match the original charger.

If you are unsure, please send photos of the battery label, charging port, and original charger label before placing your order. This information helps determine whether this compatible Yamaha e-bike charger is the correct replacement product.
