Choosing the right battery charger for your electric bicycle's lithium ion battery is a critical decision. Make sure you have the following information in hand before you select and purchase a charger:

1. The battery voltage and amperage (usually listed on a sticker somewhere on the case). 
2. Make and Model of your E-Bike
3. If your e-bike battery is an aftermarket or DIY kit, please refer to the connector pictures below to determine which battery charger you'll need.
