Refund policy

Returns & Exchanges Policy

Last updated: September 25, 2026

Accessories and non-battery products

Unused chargers, cases, wraps, connectors, and similar non-battery accessories may be returned within 14 days after delivery when they are in their original condition and packaging. For these change-of-mind returns, approved refunds exclude return shipping and any non-refundable carrier charges, except where applicable law requires otherwise.

Battery cells

Battery-cell sales are final for change-of-mind returns. For safety and traceability, shipped lithium-ion cells cannot be restocked or resold. Verified items that arrive damaged or dead on arrival are handled under the process below.

Damaged or dead-on-arrival items

Contact support@diy500amp.com within 5 calendar days after delivery. Include your order number, clear photos of the product and packaging, and a brief description of the problem.

For our voluntary damaged or dead-on-arrival return process, battery-cell claims are subject to these inspection conditions:

  • Batch or serial markings match our fulfillment records.
  • The cells are unused and have not been welded, soldered, rewrapped, charged, or installed.
  • The original packaging and shipping materials are retained for inspection.

Do not mail an item back until DIY500AMP issues return instructions or an RMA. After the item is received, inspected, and confirmed eligible, we will provide the approved replacement or refund resolution.

Legal rights, warranties, and existing refunds

The final-sale rule, reporting periods, and inspection conditions above do not limit remedies required by applicable law for defective, misdescribed, incorrect, or undelivered goods, or rights under an applicable warranty. Contact us when you discover a problem, even if more than 5 days have passed, so we can review the circumstances and any applicable rights.

A restriction on future purchases does not cancel an existing approved refund or other obligation relating to an earlier order. We do not require an honest review to be changed or removed to receive a remedy you are entitled to. Updates to this policy apply prospectively and do not remove rights or commitments attached to earlier purchases.

Do not ship a damaged, leaking, swollen, or overheated battery. Contact us first for safe handling and return instructions.
