Return & Refund Policy

Xirsix, LLC · New Mexico, USA

Effective date: 2026-10-22

1. Scope

This policy covers returns of Xirsix LTO battery modules bought directly from xirsix.com. Modules bought from a reseller or distributor follow that seller's return policy. Warranty claims for defects are covered by the Xirsix Limited Warranty (20-year, XIR-WAR-MOD6S40-001), linked here, not by this policy.

2. Return window

You may request a return within 30 days of delivery.

3. Eligibility

To be eligible, the module must be:

• Lightly used and free of damage (normal installation and use is fine; no physical damage, overcharge, overdischarge, or abuse)
• Undamaged, unmodified, with the enclosure unopened and the serial number/date code intact (same conditions as Warranty §4)
• Returned in the original packaging or equivalent protective packaging suitable for lithium batteries (see §6)
• Accompanied by proof of purchase and an RMA number issued by Xirsix

Not eligible: custom or fleet orders placed under a quote or purchase order, and modules damaged by misuse as described in Warranty §4.

4. How to start a return

1. Email support@xirsix.com (or call 1-866-4-XIRSIX) with your order number, the module serial number(s), and the reason for the return.
2. We will reply with an RMA number and return instructions. Do not ship a module without an RMA. Lithium batteries must be packaged and labeled correctly, and we will tell you how.
3. Ship the module to the address in your RMA instructions. Do not ship returns to our PO Box; carriers cannot deliver Class 9 lithium battery shipments to PO Boxes.

5. Return shipping costs

• Change-of-mind returns: the customer pays return shipping, using a ground carrier that accepts Class 9 lithium battery shipments.
• Our error (wrong item, or damaged in transit and reported per the Shipping Policy): Xirsix pays return shipping.
• Original outbound shipping charges ($80 FedEx Ground) are non-refundable on change-of-mind returns.

6. Packaging and safety (required)

Xirsix modules are lithium-ion batteries (UN 3480, Class 9) and are regulated for transport. Follow the packaging instructions in your RMA. Never ship a module that is visibly damaged, swollen, leaking, or hot. Contact us first, because damaged lithium batteries require special handling. Store and ship at partial charge (about 30–50% SOC, per the Xirsix SDS XIR-SDS-LTO40-001).

7. Inspection and refunds

We inspect returned modules, typically within ten (10) business days of receipt (matching the warranty inspection timeline). Approved refunds go back to your original payment method through Stripe within five (5) business days of approval. Your bank may take additional time to post the refund.

• Restocking fee: none for unused modules; 10% of the module price for modules that have been installed or used.
• Modules that fail inspection (damaged or modified) are not eligible for a refund. You may choose to have the module shipped back to you at your cost, or have Xirsix recycle it responsibly at no charge.

8. Multi-unit and quantity pricing

Orders priced at the multi-unit rate ($899 each for 2 or more) that are partially returned are re-priced only if a single module remains. If you keep one module, it is charged at the single-unit rate ($999) and the $100 difference is deducted from your refund. If you keep two or more, they stay at $899 each. For example, if you order three and return one, the remaining two stay at $899 each.

9. Exchanges

We do not offer exchanges. To get a different item, return the original under this policy and place a new order.

10. Defective modules

If a module arrives defective or fails later, contact us under the Limited Warranty (repair, replacement, or credit at Xirsix's discretion). Warranty remedies, exclusions, and shipping terms are in that document.
