Levy stocks Okai fleet parts by model. Batteries are available for the ES400A, ES400B, ES600P, ES410, EB100 and EB300, and the ES400 platform has deep coverage across controllers, brakes, forks, decks, lighting and body panels. Batteries and controllers are model-specific — an ES400A part is not an ES400B part unless its own label says ES400A/B.

Fitment and prices on this page were checked against the live product pages at shop.levyelectric.com on August 25, 2026. Prices change; the product page is always the authority. Compatibility that Levy has not confirmed is marked as unconfirmed rather than guessed.
Each pack is listed against one model. Okai battery packs are not cross-compatible between models, and a fleet operator swapping the wrong pack into a chassis is a problem that ends in a warranty claim at best.

This catalog exists because Levy operates and supplies shared-mobility fleets. If you are keeping a fleet of ES400s on the road, the parts pages above are the fast path; for vehicles, telematics and operations, start at Levy Fleets.
The model designation is on the compliance label on the frame, and it matters more than it looks. Several parts differ between the two revisions, including the controller, the central control system, the deck covers and the display. Levy lists ES400A and ES400B parts separately for exactly this reason, and a part whose label reads "ES400A/B" fits both.
Batteries for the ES400A, ES400B, ES600P, ES410, EB100 and EB300. Each is listed against a single model. Battery packs are not cross-compatible between Okai models, so order the one that names your scooter.
The Okai ES400 charger is sold in two connector variants, a barrel jack version and a HiGo version. They are the same charger with different plugs, and they are not interchangeable. Look at your scooter’s charge port before ordering.
Levy stocks an ES400 rear tire and an ES400 front wheel set with the tire already mounted. Separately, the 10 x 2.5 tire Levy stocks for the Segway Max series is listed as also fitting Okai ES400 series scooters.
Fleet. The Okai ES400, ES600 and EB100 are rental and shared-mobility vehicles, and this catalog exists because Levy runs and supplies fleets. If you operate a fleet and need a part that is not listed, ask — the published catalog is a subset of what is sourced.
