2. High safety: no fire and explosion in overcharge test at the voltage up to 30V and in short-circuit test, nail test, heat shock up to 130℃ test;
3. Good charging and discharging performance;
4. High discharge rate up to 10C;
5. All raw material of the batteries are environmental-friendly;
6. Wide working temperature range: from -10℃ to 60℃, extremely cold and hot weather will not affect its performance.
Description:
High-power Electric bike battery with painted metal case, Lifepo4 lithium battery of 24V 40AH
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:

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.
