Our Advantages

Lithium battery advantages:

1. The energy is relatively high. It has a high storage energy density, which has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries;
2. Long service life, service life can reach more than 6 years, lithium ferrous phosphate as the positive electrode of the battery 1C (100% DOD) charge and discharge, there is a record of 10,000 times of use;
3. High rated voltage (single working voltage is 3.7V or 3.2V), about equal to the series voltage of 3 nickel-cadmium or nickel-metal hydride rechargeable batteries, which is convenient for forming a battery power pack; lithium batteries can be adjusted to 3.0V through a new type of lithium battery voltage regulator technology to suit the use of small electrical appliances.
4. It has high power endurance, among which lithium iron phosphate lithium-ion batteries for electric vehicles can reach 15-30C charge and discharge capabilities, which is convenient for high-intensity starting and acceleration;
5. The self-discharge rate is very low, which is one of the most prominent advantages of the battery, generally can be less than 1% / month, less than 1/20 of the nickel-metal hydride battery;
6. Light weight, the weight of the same volume is about 1/6-1/5 of lead-acid products;
7. Strong adaptability to high and low temperature, can be used in the environment of -20 °C--60 °C, after process treatment, can be used in -45 °C environment;
8. Green environmental protection, regardless of production, use and scrap, does not contain or produce any lead, mercury, cadmium and other toxic and harmful heavy metal elements and substances.
