In-house LiFePO4 packs with a 3-year battery-series warranty
Vertical integration on lithium batteries is a stated factory capability. Motorcycle pages specify LiFePO4 chemistry, 72V-class model voltage, 64V or 76.8V rated packs, and a 3-year warranty on the lithium-battery series.
Named pack pages in the catalog include 76.8V packs at 30AH, 40AH, 55AH, 91AH, 230A and 314A class listings, plus other lithium-battery SKUs.
On the motorcycle side, capacity is how range is actually sold: 25AH vs 55AH on Cross / Fighter pages changes both eco-range and charge current.
The 3-year product warranty is stated for the lithium-battery series, not as a blanket claim on plastics or motors. After-sales language on the about page ties that warranty to lower operating cost for the user.
