Macfox X1S Battery & Dual-Battery Upgrade Kit
Ships to the lower 48. Bikes ship free, parts ship free over $99.
About this part
This is the 48V 10.4Ah battery pack that powers the Macfox X1S and X1S x Bs.zay, available as a direct replacement pack or as the dual-battery upgrade kit that turns a single-battery bike into a two-pack setup with roughly double the range.
The upgrade kit ships in a 4-pin and a 5-pin version, and the two are not interchangeable — check the connector on your bike before ordering. Choosing the Standard Battery option gets the pack only; a charger is not included.
The same part your bike left the factory with
A genuine vendor part, not a copy. It fits the factory mounts and connectors, so nothing else on the bike has to change.
The factory 48V 10.4Ah pack for the Macfox X1S, sold on its own or as the second-battery kit.
