1,12V 50AH lifepo4 battery for ups
2,For UPS, solar, backup power
1,We specialize in this field for nine years and mainly produce the LiFePO4(lithium)batteries.
2,The capacity of manufacturing LiFePO4 battery is 1.25 MWH per day, which makes it the biggest manufacturer of LiFePO4 battery.
3,At present, over 10.000 EVs and HEVs powered by our company have been running through cities on different road conditions.
4,The products are widely used in EV and HEV, energy storage (grid, wind-solar generating system and load shifting), UPS, military products and household appliances.
5,We maintain a long-term business relationship with the customers from all over the world, such as France, the USA, UK, Australia, Germany, India and Brazil with high quality and pretty competitive price.
Our batteries have got the certificates of CE,UL,TUV,SGS,ROHS,NQA.
The features of the LiFePO4 batteries:
1, Safe: The iron-lithium battery is more safe and reliable than the lead acid one. It does not explode or burn when bump, heavy stress, needle pricking, short circuit, overcharge and overheat.
2,Environment-friendly: Accredited with ROHS, with out any hazardous and noxious substances.
3, Small in volume and light in weight: The iron-lithium battery is about 1/2 the volume and 1/3 the weight of the lead-acid battery.
4, Powerful: able to discharge with 20C at 65.C max.
5, Steady performance: high power output,1C continuous,3C pulse for normal cells and 20 C for special design. low self-discharge rate, less than3%monthly.
6, Long cycle life: over 2000 cycles with capacity staying at 80% min.
7, Lower average price per year: the average price per year is 100 Yuan RMB less than the lead-acid battery for 5 years.
8, No memory effect: always ready for charge and use, with no need to charge after a full discharg.
9, Wide temperature range: Available for use when the temperature ranges from 20°C to 70°C .
10, Intelligent charge system: voltage of each cell can be detected ,each cell can be protected against overcharge, overvoltage ,short circuit and overheat , and so that battery can be charged balance. The capacity of readout power volume :each battery has 5LED lights to readout the capacity of the battery.
Any battery pack we produced were assembled by series and parallels of single battery cells, So you can also buy single battery cells, and DIY according to your demands.
