Hello I hope this finds you well. Recently I “converted” my UHK60 to function via Bluetooth+Battery. In my case, I wanted to do this without any deeply-involved methods. This means parts that can be ordered via Amazon Prime, no major alterations to the keyboard itself, and preferably plug & go. I was able to get it working. I did so via a USB → Bluetooth transmitter, a tiny form factory battery, and an extra usb-c cable (plus some thin Velcro tape).
This “conversion” works essentially out of box, plug and play. Simply wire up, mount if preferred, and connect. Thus far I have tested on my W11 office desktop, my personal Linux desktop, and even my Quest 3. All devices pair no issue, with full function including module/cluster elements.

Process:
- Attach transmitter to the back of the keyboard. Closer to the tilt feet the less intrusive. I believe using the riser/hollowed palm rests would result in the best final product.
- Attach the battery to the back of the keyboard ensuring placement does not block ports like charging and/or tilt.
- Wire battery to transmitter using built-in usb-c. Also wire keyboard to transmitter.
- You should see the transmitter turn on. Depending on which transmitter you get the led indicator might be different.
- Pair to device.
Battery Life:
Roughly ~
Backlight On → 8-12 hours.
Backlight Off → 20-26 hours.
(I am guessing this somewhat weaker performance is due to the lack of a power optimizer. You could bump battery size but you risk form factor. With the riser you could easily fit a larger battery)
