I recently had to open my nano-x up as the battery wires inside ripped off after an accident. When I got home I plugged it into a charger and the green and red lights both worked and the motor would spin. I then tried testing the battery by touching the wires on the old connection with the wires. Me being me I put the positive wire and the negative wire the wrong way around and now the remote won’t show up with the green light but the red charging light still works.
Any ideas on how to fix this? Or is it beyond repair?
