Product Description
Basic Performance
(1) Output with high efficiency: Standard discharge current is 0.3C-0.8C, instant impulse discharge current is 10C for 10 seconds.
(2) Good performance under high temperature, it could work under 65°C temperature. The battery structure is safe and good.
(3) Good performance under low temperature. discharge capacity decreases to over 78% under 0°C and discharge capacity decreases to over 70% under -20°C.
(4) Good safety performance: When the pressure inside the battery is too large, the one-way safety valve will release gas and heat to make sure battery perform well. When the internal pressure reaches a certain level, the valve will be open immediately which can protect the battery from burning and explosion.
(5) Good cycle life time, the discharge capacity is still over 80% after 3000 cycle times of single cell(80%DOD).
(6) It can fast charging. It could be charged to 80% within 20 minutes and charged full with 2-3h.
(7) Low cost. (8) No pollution during manufacture and usage.

Packing & DeliveringThe lithium battery is Dangerous Good for shipment by Sea and By air and they should be shipped under the regulation of UN3480.
All EVL batteries are packaged by DG plywood case and we provide UN38.3 test report and MSDS.
Please check shipping cost before place order, the lithium battery is Dangerous Good, the shipping cost is very different, so please
check shipping cost before place order.
Overview of Factory
Why choose us
FAQQ: 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 charge a solar 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 the LiFePO4/Lithium-Ion solar controller. Especially if you are using the battery as UPS (backup 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 the battery warehouse for a long time?A: Yes, Individual pricing for large scale projects and wholesale demand 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.
