Connecting the Battery
The Varstrom G80 battery features an XT60 connector for easy and secure attachment to your ebike's motor or controller. While the battery's discharge wire is not directly connected to the connector to prevent issues, a pair of free connectors with wires (battery end and controller end) are included in the package for direct connection if needed.
Easy Connection Without Tools (if applicable)
If you need to connect the battery to a controller or motor that does not have a pre-attached XT60 connector, follow these steps:
- Use scissors to carefully cut off a small section of the rubber insulation from both the battery discharge wire and the connector line to expose the metal wire.
- Connect the red wire from the battery to the red wire of the connector, and the black wire from the battery to the black wire of the connector. Twist the exposed metal wires of the corresponding colors together firmly.
- Wrap the connection securely with electrical tape to insulate and protect it.
After connecting the connector line to the battery, the other end of the connector can be directly connected to your ebike's controller or motor. This battery is supplied with XT60 connectors. If your setup requires different types of connectors, please contact Varstrom support before purchasing.
