I did something similar for my Classique, though a bit less elegant (and at twice the price if you take the false starts into account) and now that jockey wheel problem is in the past. But it created a new problem.
I can now cover a much ground with my ewiks as the battery will allow once my trailing cable to the power plug runs out of length. And my new anxiety became how hot the motors got over an extended distance without stopping to attend to obstacles or blown fuses. They felt like they were getting pretty warm, but how hot is too hot?
I talked to Dactyltech about this because that’s where I got the remote control from and within a week the sent me an upgrade kit that can display the temperature of the motors on my mobile. You clip a heat probe to the outside of each motor, run a cable back to the control unit where it has a new socket to plug into, and the latest version of the app give you a continuous readout of each motors temperature.
They claim it also shuts the motors down when they start to overheat, but I haven’t tested that part yet. And I hope I don’t have to.
This is what it looks like:
