Please note that this model of battery is produced in a high-altitude factory and nitrogen is injected into its production. If there is a slight bulge, it is normal and does not affect its normal performance. Please do not worry. This phenomenon is improved by compression and multiple cycles.

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,It will takes 30-45 working days for delivery .Generally, after 35-45 working days, the package will arrive at the transfer station. After the customs clearance is completed, the package will be picked up and delivered, and the logistics information will be updated.
3,Once UPS's transportation number is updated, you can receive the goods within 3-5 days at most.

Reminder

DIY battery pack must get the cells balanced (same voltage ) before assembly. Later if there happens don't know how to assembled or unbalanced assembly is not accepted refund. please consider before taking orders, place order means you have agreed. thank you for your cooperation!

These situations not provide return nor refund

1: after the assembly or assembly process happen any problem, such as the protection board connected to the wrong wire burned lead to battery damage, charger failure, the assembly error or unbalanced assembly, etc.

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

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: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.
