Why can't I order directly from the store?

We cannot provide accurate logistics prices for all countries directly. Please contact us for specific shipping inquiries.

Why is my tracking number not updating?

Due to strict transportation terms for batteries, tracking updates only occur after customs clearance in your country.

What is the return policy for unused cells?

Returns are accepted only if cells are unused with intact electrodes and no welding. Buyers must pay shipping fees for returns.

Product Q&A

Q:Does the battery include BusBar connectors 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?

Yes, we match and balance all cells to ensure that the internal resistance, voltage, and capacity are completely matched and balanced before delivery.

Q:What is the life expectancy of this LiFePO4 cell?

The typical estimated life is 5-15 years, or 2000 to 8000 cycles, depending on usage conditions.

Q:Can I use a normal solar controller for this battery?

We recommend using a LiFePO4/Lithium Ion solar controller. Lead Acid controllers may damage the PCB due to pulse current.

Q:Do you support product customization?

Yes, we support customization including logo, appearance, and accessories, subject to different MOQ limits.
