Ive had a few electric wheelchairs and scooters run out of power. When they do, they just go really slow at full throttle and you get a low battery indicator.
One chair I had the wires come unsoldered from the motor. I drove it in arcs by pushing the joystick forward, then jerking it in reverse quickly.
Another I had the charger socket come unsoldered. I cut the connector from the charger and hooked up 2 alligator clips. I then tested the batteries to find the 2 24 volt leads as it took 2 batteries and matched it up.
