Description:

24V 40AH Electric Bike Lifepo4 Battery Pack with Constant Discharge Current of 35A

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-NixCoyMn 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:

Different Lithium Battery Material Comparision Table
NO. Parameters Li-Co2 Li-NiCoMn Li-MnO2 LiFePO4
1 Energy density (g/cm3) 2.8~3.0 2.0~2.3 2.2~2.4 1.0~1.4
2 Specific area (m2/g) 0.4~0.6 0.2~0.4 0.4~0.8 12~20
3 Capacity density (Ah/kg) 135~140 155~165 100~115 130~140
4 Voltage 3.7 3.6 3.6 3.2
5 Cycle life >300 >800 >500 >2000
6 Transition metal Poor Poor Rich Very rich
7 Material cost Very high High Cheap Cheap
8 Environmental performance Contain Co Contain Co & Ni Non-toxic Non-toxic
9 Safety performance Bad Good Better Excellent
10 Application area Small battery Small battery Small power battery Power battery Power battery Large capacity power supply

From this chart, We can see Li-fepo4 battery has the most excellent overall performance.

Applications:

electric bike, electric wheelchair, electric scooter, electric motorcycle, golf cart, electric robot, vacuum cleaner, electric mower, wind/solar energy storage ...

Electric Bike 24V LiFePO4 Battery Pack 40AH With 35A Constant Discharge Current

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.
