The Difference On Batteries

1.Safety：

The P.O bond in the lithium iron phosphate crystal is stable, it is difficult to decompose, and it will not generate heat even if it is charged at high temperature and overcharged. At the same time, the lithium iron phosphate battery is the highest safety product in the lithium battery series and has passed international safety certifications such as uL and CE. The thermal runaway temperature can reach up to 600 ° C, and no combustible gas such as hydrogen will be generated. Energy storage type lithium iron phosphate battery cells are equipped with PTC (Positive Temperature Coefficient Thermistor) CID (explosion-proof pressure valve). The battery pack is equipped with protective plates such as overshoot, overdischarge, overcurrent, short circuit, static electricity, etc., and its safety Recognized.  

2.Charging and Discharging Circles

LiFePO4 battery charging and discharing cycle life up to 2000 ~ 3000 times

3. The advantage of Perfermance

The LiFePO4 battery has good high and low temperature performance, and the working range is -30 ℃ ~ + 80 ℃. The low temperature of our company produces LiFePO4 battery can reach about 70% of rated capacity under -40 ℃ environment. , No memory effect, light weight and small size. LiFePO4 batteries weigh only 1/3 of the same capacity as lead-acid batteries, and less than 2/3 in volume.

4. Environmental protection

The LiFePO4  battery does not contain any heavy metals and rare metals, is non-toxic, non-polluting, green and environmentally friendly. It has passed the SGS certification, complies with European ROHS regulations, and is included in the "863" high-tech plan during the "Tenth Five-Year" period. Lead and acid in lead-acid batteries are hazardous wastes strictly controlled by the Ministry of Environmental Protection. Among them, lead is listed in the environmental protection black five categories, causing pollution to the environment.

5、LiFePO4

6、The Function on BMS

The Basic Protection Function on BMS：Over-Charging、Over-Discharging、Short-Circuit,Over-temperature,NTC and so on.

7、The Testing date on LiFePO4

8、The discharing date from Effort

Since 2017-2019，under 60 degrees，24 hours of uninterrupted work, and a charging experiment of 48pcs EEC08 and EEC15 emergency power supply every 3 months. After 3 years of testing, the average battery capacity is ≥95%.
