There are a large number of lithium battery electric wheelchairs on the market, and everyone is no longer unfamiliar with lithium batteries. So what is the difference between lithium battery electric wheelchairs and traditional lead-acid battery electric wheelchairs?

The main differences between lithium battery electric wheelchair and lead-acid battery electric wheelchair are as follows:
1. The weight of lithium battery electric wheelchairs is much lighter than that of lead-acid battery electric wheelchairs. Traditional lead-acid battery electric wheelchairs weigh as little as 30 kilograms and weigh one or two hundred kilograms. The lithium battery electric wheelchair weighs only about 20 kilograms.
2. The service life of the battery is different. Lead-acid batteries are generally fully charged and discharged about 400 times, with memory, and the service life is about two years. At present, most of the lead-acid batteries are maintenance-free lead-acid batteries. As the number of uses increases, the batteries will gradually lose water, resulting in poorer power storage capacity. Lithium battery has strong durability, slow consumption, can charge and discharge more than 500 times, and has no memory, and the service life is about 3-5 years.
3. Lead-acid battery electric wheelchairs with the same capacity have less endurance than lithium battery electric wheelchairs. Due to the light weight of lithium batteries, the vehicle has a smaller weight, saves electricity, and has a longer cruising range.

From the above analysis, it can be seen that the purchase of batteries for electric wheelchairs and smart elderly electric scooters should mainly be based on the user's own use needs. If there are the following requirements, it is recommended to choose lithium batteries:
1. Because there is no elevator and other reasons, the battery needs to be removed frequently, and the battery needs to be screwed upstairs to charge, then you need to choose a lighter weight lithium battery configuration;
2. You need to get on the plane. In this case, you must choose an electric wheelchair scooter equipped with lithium batteries, because lead-acid batteries are not allowed on the plane;
3. I hope to choose a lighter weight electric wheelchair scooter, so that it is convenient to carry out, and it is more convenient to put in the trunk or check in.
