Description:
Lithium polymer battery pack/module of 24V 20ah, lifepo4 battery for electric wheelchair / electric scooter
Li-FePO4 battery modules and BMS solution:
Our company is a manufacturer of Li-FePO4 cells
Li-FePO4 battery modules and BMS solution:
Our company was a manufacturer of Li-FePO4 cells, we make and developing Battery Management Systems(BMS) battery solution, our battery modules have:
12v 8Ah, 12v 10Ah, 12v 20Ah, 12v 40Ah 12v 50Ah
We use this standard modules to build 24V, 36V, 48V, 72V...etc, and support different energy BMS solutions to support our customers
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.

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 HKNE battery’s excellent performance and good consistency.
3. One-stop lithium battery system solutions. HKNE’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.
