Run FM+ batteries on an older Fusion base
The FM+ Battery Adaptor bridges the gap between the shorter FM+ batteries and Fusion units, enabling compatibility between two product lines that wouldn’t otherwise fit together. It’s for Fusion system owners who purchased their units before September 2026, when FM+ batteries launched — newer Fusion kits include it automatically.
With it fitted, you can run the FM+ 650 or FM+ 430 battery on your existing Fusion, opening up configurations ranging from maximum runtime through to a lighter, more responsive setup.
Key Features
- Toolless Connection — Integrated Quick Lock Tabs for fast installation and removal
- Secure Unified Connection — Between battery and Fusion base
- Just 100 Grams — No installation hardware required
Compatibility
For Fusion units purchased before September 2026. Not required with the MAX+ system, and not needed on newer Fusion kits which include it as standard.
Why We Recommend It
The simple fix for existing Fusion owners who want to run the newer, lighter FM+ battery range without upgrading the whole system.
