Batteries used to power electric wheelchairs and other mobility vehicles for people with disabilities operate differently than those in cars or motorcycles. In a wheelchair's electrical system, there is no charging during movement, which means the battery must be charged externally using a dedicated charger. These vehicles are not equipped with systems that recharge the battery while in use.
Due to this operational characteristic, wheelchair batteries must meet specific requirements to function reliably. They need to be designed for cyclic use, resistant to deep discharges, have a low self-discharge rate, and support fast charging. Ideally, they should also be free of memory effect. Additionally, the more frequently the wheelchair is used, the higher the battery capacity should be to allow for longer travel time between charges. Battery size and weight are also critical factors, as the battery must fit within the compact dimensions of the wheelchair.
We offer LiFePO₄ batteries for electric wheelchairs that provide long service life and meet all the above requirements, making them the optimal choice for this type of vehicle. The most common solution in electric wheelchairs involves using two batteries with matching specifications, connected in series.
