Why can't I order directly from your store?

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

Can distributors cooperate with your battery warehouse long-term?

Yes, individual pricing for large scale projects and wholesale demands is available.

Why hasn't my UPS or Fedex tracking number been updated?

Because the battery is a special commodity, logistics is hard to ship. We use special sea/land transport, meaning tracking updates after customs clearance.

Product Q&A

Q:Does the battery include BusBar connector and screws?

This depends on whether you ordered the copper busbars separately. We have high-quality copper busbars available; please inquire.

Q:Are the cells balanced upon delivery?

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.

Q:What is the life expectancy of the lifepo4 cell?

The typical estimated life of the Lithium Iron Phosphate (LiFePO4) battery is 5-15 years, or 2000 to 8000 cycles.

Q:Can I use a normal solar controller for LiFePO4 battery with PCB?

We always recommend to use LiFePO4/Lithium Ion solar controller. Lead Acid controllers might damage the PCB, so the battery won't be protected.

Q:Do you support product customization?

Yes, we support product customization. This includes, but is not limited to, different customization requirements such as logo, appearance, and accessories.
