The FM+ Battery Adaptor is required when using the FM+ Battery Range with Fusion units.  The adaptor extends the length of the smaller batteries to fit securely in the longer Fusion unit.

Fusion customers who purchased their system prior to release of the FM+ Batteries (September 2026) will need to purchase an adaptor with their FM+ 650 Battery. Fusion systems after this date have the adaptor supplied in the kit.

The FM+ Battery Adaptor creates a toolless and secure extension between the shorter FM+ battery range and the Fusion unit, allowing both the FM+ 650 and FM+ 430 to click into the system with ease.

Integrated Quick Lock Tabs make fitting and removing the adaptor fast and intuitive, while maintaining a solid, unified connection between the battery and Fusion base.

This gives Fusion riders more flexibility in how they configure their setup, ranging from maximum runtime with the Fusion 860 to a lighter, nimble and responsive feel with the FM+ battery range, without changing the core system.
