Expion360 OEM Frequently Asked Questions

What warranty do Expion360 batteries come with?

We stand behind our energy solutions with an industry-leading 12-year limited warranty. This reflects our confidence in our premium LiFePO4 chemistry and internal build quality. For high-volume OEM partners, we can discuss tailored Service Level Agreements (SLAs) to match your specific product lifecycle requirements.

What certifications do your batteries have?

Safety and compliance are non-negotiable for us. Our batteries and internal components are engineered to meet or exceed:

  • UL 1973 Listing: For stationary and motive auxiliary power.
  • UN 38.3: Ensuring safe transport via air, sea, and land.
  • UL 1642: Certified cells for maximum safety at the foundational level.
  • IP66 Rated Enclosures: Depending on the model, providing protection against dust and high-pressure water jets.
Do you offer custom battery configurations for OEMs?

Yes. While we have a robust catalog of standard form factors (Group 24, 27, 31, etc.), we specialize in collaborative engineering. We can work with your team to develop custom battery management system (BMS) parameters, specialized casing, or unique power distributions to fit the specific footprint of your product.

Where are Expion360 batteries manufactured?

Expion360 is proudly headquartered in Redmond, Oregon, USA. Our batteries are designed, engineered, and quality-tested right here in the Pacific Northwest. We source the highest grade lithium iron phosphate cells globally and oversee the final assembly and rigorous multi-point inspection process in our domestic facilities to ensure premium quality control.

What is the typical lead time for OEM orders?

For standard inventory items, we typically ship within 2–4 weeks. For custom configurations or high-volume wholesale orders, lead times generally range from 12–16 weeks, depending on the complexity of the build and supply chain schedules. We provide our OEM partners with a dedicated account manager to ensure transparent forecasting and "just-in-time" delivery.
