控制器

Controller

The mainboard uses a 6-layer board with gold-plating technology, copper thickness of 20Z, CPU employing the high-performance processor STM32H7, continuous bus current of 450A, voltage range of 40-90V.

Battery

The shell of battery is processed using high-quality 4mm thick aluminum alloy material, internally filled with gel to promote uniform heat dissipation, effectively preventing self-ignition, and achieving IP67 waterproof and shockproof ratings. Equipped with a dual safety protection Battery Management System (BMS) and a fuse module to prevent overcharging, over-discharging, overloading, and short circuits. Utilizing top-tier Samsung 50S premium 21700 battery cells, the 72V 30Ah battery pack has a total capacity of 2160Wh, providing a range of up to 175 miles in pedal-assist mode and over 70 miles in throttle-only mode.
