Frequently asked questions

LFP battery uses LiFePO4 as the cathode material. The battery composed of LFP material has long service life, long cycle, large discharge power, high stability, high cost performance and is very friendly to the environment. The life cycle of each battery can be recycled more than 4000~10000 times and used for about ten years. In the past, the cycle life of our commonly used lead-acid battery was less than 400 times, the service life was about two years, and the volume was large and bulky. In contrast, the performance of lithium battery is better than that of lead-acid battery, which is a new choice for people to buy batteries.
 

Grade A batteries have original factory data and original QR codes,  all indicators meet the specifications and have the original manufacturer's warranty.
Grade B batteries generally do not have QR codes or the QR codes are erased, or marked with B codes. The batteries may have size deviations, insufficient capacity, excessive internal resistance, appearance defects, poor discharge performance, etc. However, some minor problems still do not affect the use of energy storage.
Grade C batteries, which have no specific standards, are generally classified as recycled batteries.

Yes. OEM/ODM services include branding and system design support.

The working limit temperature of lithium iron phosphate battery is generally -40～60℃. When the temperature is below 0℃, the performance of the battery is seriously reduced and the activity is seriously reduced. Therefore, below 0℃ is the low temperature stage. When the temperature is above 40℃, the SOC of the battery may reach 1.1, so above 40℃ is the high temperature stage. The working temperature of lithium electronics is generally 0～40℃.

Generally speaking, the cycle life of LFP can reach more than 4,000 times,80%DOD(as EVE 280Ah more than 8000+times，Hithium 280Ah more than 10000+times), and NMC is about 2,000 times,80%DOD.
