# Part availability, checked 2026-10-25

Data: `catalog/availability.json` (historical file) . That file has every seller, URL and stock note for each part. In stock = at least one seller shows it in stock or orderable now. Unit counts are rarely shown. Lead time is the upper bound a seller states; '?' means not stated. 60 V = the manufacturer's stated max voltage is at least 60 V (full FLEXVOLT). '?' = no max voltage stated. EUR converted at 1.1193.

## Key findings

-   **RobStride (RS-02/03/04/06) are the only leg actuators rated to 60 V** , with a stated range of 15/24-60 V. That leaves zero margin at full charge, and regen can push the bus past 60 V, so a bus clamp or brake resistor is needed. Seeed lists them 'In stock' from its China warehouse with no count or lead time. rcdrone.top's cart accepted 150 RS-03, 78 RS-04 and 76 RS-06. Amazon is unavailable; roboticscenter.ai is backordered, 4-6 weeks.
-   **Damiao J-series are capped at 52 V** ; the exception is the J10010L at 58 V, which covers 45-58 V in use but not 60 V at full charge. All are in stock at roboticscenter.ai (US), 1-3 weeks.
-   **CubeMars AK series are capped at 52 V** (AKA manual V3.0.0). RobotShop US has the AK70-10, AK80-9 V3 and AK80-8 in stock. The AK80-64 and AK10-9 V3 are backordered at RobotShop US and EU.
-   **Unitree GO-M8010-6** is the easiest to buy (official US store, ready to ship, $369) but runs at 12-30 V, so it is unusable on this pack.
-   **Wheels:** the BotWheel is orderable only as a $269 2-pack, and its max voltage is not stated (speed is quoted at 24 V). UUmotor 6.5 in and 8 in 48 V hub servos have large stock counts (71-967) at $145-165, but none states a max voltage, so 60 V is unconfirmed.
-   **Drivers:** only the Flipsky 75100 (single $65 or dual $172, 14-84 V) is in stock and rated for 60 V. The ODrive Pro is in stock but maxes at 58 V; the ODrive S1 is sold out and maxes at 50.5 V.
-   **Blocked during checking:** RobotShop search, Foxtech, AliExpress (captcha or empty store page) and some rcdrone/aifitlab quantity checks.
