In an externally powered wheelchair, what powers the drive system?

Explanation:
The drive system in an externally powered wheelchair runs on stored electrical energy from deep-cycle batteries. These batteries feed the electric motors that propel the wheels, providing sustained power that can be recharged when needed. Manual hand-crank propulsion isn’t used for this type of chair, a gasoline engine isn’t typical for indoor mobility devices, and a wind-up spring isn’t practical for delivering the reliable, controllable power required. Deep-cycle batteries are designed for steady discharge over long periods, making them ideal for powering mobility devices.
