Electric wheelchair is power-driven, its battery and motor are two very key parameters, when you buy, there are two kinds of batteries, lead-acid batteries and lithium batteries, lead-acid batteries are cheap and easy to maintain, but heavier; lithium batteries are lightweight, and longer service life, and the disadvantage is that they are more expensive. There are bldc-motors and Brushed DC Motor, bldc-motors save electricity, are relatively low noise, and are maintenance-free, in addition to being a little more expensive, other than Brushed DC Motor, how to choose mainly depends on the actual demand and budget. Look below to see which electric wheelchair battery is better and whether electric wheelchair Brushed DC Motor or bldc-motors is better.
1. What kind of batteries do wheelchairs use?
In the purchase of electric wheelchairs, the battery is an important consideration, electric wheelchair batteries are mainly lead-acid batteries and lithium batteries, so which battery-electric wheelchair is better?
1.1 Lead acid battery
The advantage of lead-acid batteries is that they are cheap, durable, and easy to maintain, the disadvantage is that they are heavy, a 12V lead-acid battery weighs about 10 kilograms.If you want affordable lead-acid battery electric wheelchair please contact us!
1.2 Lithium Battery
The advantages of lithium batteries are lightweight and longer life. The disadvantage is that they are expensive to sell, and the cost of replacing the batteries at a later date is also higher than lead-acid batteries: a 10-amp lithium battery costs about $100.Electric wheelchairs with lithium-ion batteries are usually lighter, if you are looking for a lightweight portable electric wheelchair please contact us!
Therefore, in general, choose which battery-electric wheelchair or look at the actual demand: lightweight electric wheelchairs are configured with lithium batteries, if there is a need to go out, to go on the plane, then choose lithium batteries (12 amps and the following lithium batteries can be directly brought on the plane); if the budget is lower, want to save money, do not pursue the lightweight, choose the lead-acid batteries are also OK.
2. What kind of motor is needed for a wheelchair?
When you buy a power wheelchair, in addition to the battery, the motor is also very important, the motor of the power wheelchair is mainly divided into Brushed DC Motor and bldc-motors, two kinds of motors have their advantages and disadvantages:
2.1 Brushed DC Motor
The advantages of a Brushed DC Motor are the strong driving force, it is easy to go up some small slopes, the starting and stopping are relatively smooth, and the cost is lower. The disadvantages are power consumption, the need to configure large-capacity batteries, resulting in increased weight of the vehicle, in addition, the need for regular maintenance, and more trouble.If you want a cheap electric wheelchair, you might consider a brushed motor wheelchair.
2.2 Bldc-Motors
The advantage of Bldc-Motors is that it saves electricity, with the same capacity battery, the electric wheelchair installed with brushless battery can run farther, and the noise is relatively small, indoor driving at night does not affect the rest of the family (of course, it is not completely silent, the wheelchair runs no matter how there is a sound, mainly the sound of the tires rubbing on the ground); in addition, it is free of maintenance, and the service life is longer. The disadvantage is that it is expensive. Compared to Brushed DC Motor, Bldc-Motors is about 100 dollars more expensive!If you want a wheelchair electric lightweight, you might consider a Bldc-Motors wheelchair.
As you can see, it is advisable to buy a power wheelchair from bldc-motors if you are on a budget.
