Capacity and range
Launch materials cited a 99 Wh lithium-ion battery and approximately 15 km of range. Watt-hour capacity is only part of the story: rider weight, terrain, mode selection, and use of regenerative braking shift real-world results. Mellow's four riding modes existed partly to stretch energy by capping acceleration and top speed in lower profiles.
The 99 Wh figure also sat near common airline carry-on battery limits discussed in the period — a deliberate portability choice for travellers who wanted fly-with-board flexibility when regulations allowed, though rules vary by airline and jurisdiction and must be verified independently.
Weight and integration
Battery mass contributed to the Drive's 3.9 kg total weight. Integrating the pack inside the truck module protected cells within the IP65 envelope rather than exposing a swappable brick — simplifying sealing at the cost of field swap convenience. Owners historically charged via documented connectors and followed temperature guidance in owner materials.
Safety and lifecycle (historical guidance)
Lithium packs require sensible charging practices: compatible chargers, avoidance of water ingress despite IP ratings, and storage partially charged for long idle periods.
