The selection of battery capacity for lithium battery electric wheelchairs depends on the following factors:
Distance of use: Firstly, you need to consider your daily usage needs, that is, the distance you usually need a wheelchair to travel. If your daily activities have a wide range and require a longer range of endurance, then you should choose a wheelchair with a larger battery capacity.
User's weight: When the user's weight is heavy, the electric wheelchair's motor requires more energy to drive, thus requiring a larger capacity battery.
Road conditions: If a wheelchair is frequently used on steep or uneven roads, the battery consumption will be faster, so it is also necessary to consider using high-capacity batteries.
Battery type: Lithium batteries have a higher energy density compared to lead-acid batteries, and have a larger capacity and longer range under the same volume.
Generally speaking, the following are some reference standards:
Short distance use: If your usage distance does not exceed 10 kilometers per day, choosing a 12-24 ampere hour (Ah) battery is usually sufficient.
Medium range usage: If your usage distance is 10-20 kilometers per day, it is recommended to choose a 24-40 ampere hour (Ah) battery.
Long distance use: If your usage distance exceeds 20 kilometers per day, you may need a battery of 40 ampere hours (Ah) or more.
