Description:

 

24V 10Ah lithium ion battery for electric wheelchair (LifePO4 battery)

 

Compared with the same capacity lead-acid battery, LiFePO4 battery is 1/3 smaller in size, 2/3 lighter in weight, 5 times longer in cycle life, more economic and eco-friendly.

LiFePO4 battery replacing Lead acid battery is an inevitable trend.

Compared with same capacity Li-NixCoyMnz battery, LiFePO4 battery is 2.5 times longer in cycle life, also most the same in weight & size.

 

 

Basic knowledge:

 

Lithium ion battery, classified by the anode material, can be divided into li-MH,Li-Co2, Li-NixCoyMnz, and Li-FePO4, etc.

Classified by the battery shell, can be divided into plastic shell, stell/iron shell and aluminum shell.

All these lithium ion batteries have their own advantages. The technical data of their comparative performances is as follows:

Product advantages:

 

1. Long cycle life (2000 cycles) is several times greater than Ni-MH, Ni-Cd or lead-acid.
2. No toxic, or polluting material(such as lead, cadmium, mercury) is contained in lithium battery, which is a kind of green battery.
3. High safety. LiFePO4 is an intrinsically safer cathode material than Lithium-ion since exothermic reactions can not occur in batteries based on this material LiFePO4 cells do not incinerate or explode under extreme conditions.
4. Good performance in high-current discharge cycles. We can design different capacity and size according to your demands.
For many applications, our battery systems result in significantly lower total cost of ownership over lead acid because lighter-weight, longer-life batteries means fewer replacements, reduced maintenance and service costs, less shipping and material handling costs, and lower total inventory carrying costs.

 

 

Company advantages:

 

1. Advanced polymer lithium-ion battery technology system ensure the correct technical direction and advanced leading technology
