This was part of a short lived hobby of mine. It’s been stashed away for a number of years; the batteries have been fully discharged and are bricked. Reddit forums suggest the batteries can be repaired/recharged. However, I don't have the technical knowledge or the tools to bring them back to life, so I’ll include them for the hands of someone more capable. I have the thumb controller, though that is on a separate listing and not included in the price of this sale. I can do a deal for the bundle consisting the Ronin-M and Thumb controller.
