More on Celebrity X motor overheating. Brushes look good. Brake does not seem to be dragging, Batteries are about 5 years old but hold a good charge when not in use for months. I do not know how old the scooter is but batteries were dated when put in new so I assume it is about 8 years old.

If the motor is overheating, it is drawing far more current out of
the batteries than it is supposed to. Assuming it is 2 x 13v x 33ah
batteries, these are good for about 2 to 3 years on my scooter and 'wheelchair. AGM (absorbent glass mat) lead acid batteries do deteriorate over time due to battery chemistry.
Although the batteries may appear to take a charge
and the voltage 12.6volt x 2 = 25.2 volts nominal, with no load
on them, the motor controller takes a whack of current to get you going.
I have an digital voltmeter/ammeter installed on my Pride XL scooter and I was amazed how much current the motor/motor controller takes from the batteries. 50 to 80amps on startup.
If the battery voltage drops due to the age of the batteries, as the
energy is being used up from them, the current required by the
motor for rotation has to go up, and that will cause overheating of the controller and the motor. It is Ohms law plain and simple
the less voltage available-the more current required to do the
work and current creates the heating effect.
I replace my batteries every two years. Can't take a chance on
being stuck with discharged batteries.
