Description
Tech Compatibility Note: This battery configuration is designed specifically for the high-capacity, heavy-duty frame layout of the FM 750x. Because of its expanded, high-output structural architecture and specialized 20 AH energy footprint, it is not compatible with the standard FM 750, FM 500, Hellbender Max, or XP 500 Carbon models. Always verify your specific Fission platform geometry before ordering a spare or replacement core.
High-Density Endurance. Field-Ready Range.
Deep backcountry exploration requires complete power confidence. Built with premium, tier-one LG cells, this high-capacity energy core is the exact original-equipment manufacturer (OEM) powerhouse shipped with your flagship FM 750x. Engineered to handle the high electrical current demands of our 1200W peak output hub system, it ensures linear power delivery without thermal throttling, even when climbing sustained mountain fire roads under heavy load.
The smart, lockable housing features an integrated key-cylinder interface for absolute security against trail vibration and theft. Designed to blend seamlessly into the down tube architecture of the FM 750x frame, this pack shields its high-capacity internal cell structure against driving rain, mud, and jarring trail debris. Keep it as an on-the-fly spare in your hunting pack or pannier bags to instantly double your range and guarantee a safe return from the deepest backcountry timber.
