Description:
24V 30Ah 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:

Note:
We are a manufacturer, not a retailer. And due to the battery is
not good for store a long time, all the battery packs are made once
the order is confirmed.
Sample battery pack delivery time is about 15~20 days. If you can't accept the delivery time, we can just say sorry!
Sample battery cells can be delivered at once because we have many cells in stock.
When you place an order of battery pack, please kindly tell us the
details as follows:
1.What's the Volt and Amps of the battery you want?---
2. what's your limitation to the battery size
(length*Width*height)? ---
3.What's your wheelchair's motor power?---
4. Do you also need a charger?---
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
2. Excellent procedure quality tracking control system ensure HECO
battery’s excellent performance and good consistency.
3. One-stop lithium battery system solutions. Heco’s research and
development team include electronic engineer, mechanical engineer,
structure engineer, whom could offer our clients one stop solutions
including BMS, charger, battery pack structure, and overall
applications.
4. Intimate and in time reacting service system. We always try to
offer more than expected, do more than required.
