Very Important! About delivery and transportation Time&Please note: we do not accept the dispute of no update logistics!

1,Because the battery (especially the high-power battery you purchased) is a special commodity, the terms of transportation are very strict, all logistics companies in China, including China Post, UPS, FedEx, DHL, are unable to directly transport electricity Pool,

2,So we will start to transport your order from Hong Kong. Once the battery arrives in Europe or US, we will declare for import at the European or US customs. When the battery passes through the European or US customs, we will send it to you by UPS or FedEx. so the ups number we provide will not be updated before the battery passes the customs. This is normal.

3,Once UPS's transportation number is updated, you can receive the goods within 3-5 days at most.

If we can't find the updated information after delivery, and the transportation time is still within the time we promised, please don't bring up a dispute.

FAQ

Q：Does the sending battery include BusBar connector and screws?

Yes ,we ship the battery with the  BusBar connector and screws

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  controller work fine?

A: For LiFePO4 / Lithium Ion battery, we always recommend to use 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 I can't buy cells from your store？

A: This is usually unable to provide accurate logistics prices for your country. If you have any demand, please feel free to contact us

Q:Why hasn't my ups or Fedex transportation number been updated?

A: This is normal, because 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:Is 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.
