Couldn't load pickup availability
Description
After a decade of experimenting, myself and Lia worked tirelessly for almost a year to bring to the community a controller box that finally ticks all the boxes.
Features:
- Built-in State-of-the-art Upgraded Thor301 with native LED support, beeper, and onboard VESC Express.
- Exceptional cooling due to the anodized aluminum and an IMS (Aluminum base) controller.
- Includes front LED and Status LED in the box.
- A Beautiful and sleek CNCed Aluminum box, anodized to perfection, or a budget-friendly Die-cast box (both options have similar heat-dissipation and have no other differences).
- Strong Polycarbonate see-through lid.
- Built-in Motor connector for Superflux, M20 Gland for battery pack, switchport, and GX-16 2-pin Charge port, along with a Switchcraft equivalent Footpad port that is plug-in compatible with out new footpad and footpad connector, and can also be replaced with any other XR style footpad plug).
- Fits any XR-style frame and rails for the original riding experience.
- Space in the front for a 2S2P split pack, and a handle!
This is a full plug-and-play box with the VESC tested and setup (requires motor calibration and IMU setup via VESC tool). The user has to only open the Lid and connect their preferred battery. Fungineers charger is preferred but other GX-16 style chargers will fit in the charger port.

Thor301 Documentation









I got the full X7 build aside from WTF rails. I've been flying around town. System works for me every time. The speed on hills is addictive. Love It! Will buy again when future innovations come out!
I’ve been running the Thor301 in my custom build (Funwheel motor, 20s2p P45 split pack) and it’s been rock solid for the past week. It delivers smooth, predictable power and handles without flinching; making it a clear step up from the 300. That said, going VESC isn’t without risk. it takes time, knowledge, and some trial and error to get things dialed. the performance and flexibility make it worth it. Really hope I don’t run into trouble. The unit itself looks like it can handle some trail abuse.
started with a stock XR and rode that for 3 months, it just kept dumping me. Then installed the XRV and rode that for about a year. It was much better, but had its own quirks, like not being able to turn it off when the battery was too low, and the status light only working sometimes. Now I've installed a Thor 301, and after configuring it, everything just works.
The Fungineers complete boxes and battery modules are a cheat code. No other balance.board company provides the same level of value as Fungineers, and their support and service is fantastic as well.
All the details are thought through here. It’s worked well, and it was plugged and play for me.
