Product Description
Now we provide 3.7V50Ah NCM Lithium Ion batteries manufactured from CATL, one of the leading lithium battery manufacturers from China.
Here are four advantages of our 3.7V50Ah CATL NCM batteries
1.A high energy density. The energy density of a battery is the amount of energy released per unit volume or mass of the
battery, the higher the energy density of the battery, the more energy is stored per unit volume. The energy density of LiFepo4 batteries is around 150wh/kg and the energy density of CATL NCM batteries is around 200wh/kg.
2.A good cycling performance. The cycle life of ternary lithium battery is about 3000 times.
3.A long battery life. According to the calculation of 1000 times of ternary battery circulation, a complete charge and discharge in three days can achieve a service life of 8.3 years. Even with the loss process, it can also reach more than 7 years.
4.A Good low temperature performance. The low-temperature limit of NCM lithium battery is -30℃ and the low-temperature discharge performance is good. Under the same low temperature as that of lithium iron phosphate battery, the range of attenuation in winter less than 15%, significantly higher than that of lithium iron phosphate battery.

Q:What is the life expectancy of a Lithium battery?
A: The typical estimated life of the Lithium Iron Phosphate (LiFePO4) battery is 5-15 years or 2000 to 8000 charge cycles. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again.

Q:If I want to solar charge LiFePO4/Lithium Ion battery, which already has PCB, would a normal SLA controller work fine?
A: For LiFePO4 / Lithium-Ion battery, we always recommend using LiFePO4/Lithium Ion solar controller. Especially if you are using the battery as UPS (back up power supply). The Lead-Acid solar controller will constantly provide pulse current to the battery, in the long run, it might damage the PCB. So the PCB won't be able to protect the battery when it should be.

Q:I am a distributor. Can I cooperate with battery warehouse for a long time?
A: Yes, Individual pricing for large scale projects and wholesale demands is available

Q:Why hasn't my ups or FedEx transportation number been updated?
A: This is normal, in countries with tariffs, our packages need to pass the customs of your country before they can be delivered to the local UPS or FedEx. Once they pass the customs and update the transportation number, you can usually receive the goods within 3-5 days.

Q:Are the cells I bought balanced?
A:we know the importance of maintaining the consistency of each cell in the battery pack, so we will match and balance all cells to ensure that the internal resistance, voltage, and capacity of cells are completely matched and balanced before delivery. This process is very necessary.
