Return & Refund Policy

Thirty days, original condition, an RMA number, and ground transport for anything with lithium inside: the whole process is on this page, including the timelines we hold ourselves to.

1. Summary at a Glance

2. Return Window and Conditions

Standard catalog products may be returned within 30 days of the delivery date shown by the carrier. To qualify, the product must be unused and uninstalled, in its original packaging with terminal covers and dividers, with every cell QR code and serial label intact and legible. A cell that has been wired into a pack, charged in service or clamped into a fixture is an installed product and no longer returnable as new; if it is faulty, that is a warranty matter under the Warranty Policy instead.

3. How to Start a Return

1. Email sales@shinkopower.com with your order number, the items to return, and the reason.
2. We reply within one business day with an RMA number, the return address, and, where we cover transport, a prepaid ground label or freight booking.
3. Pack the goods in the original packaging with terminal covers fitted, write the RMA number on the outer carton, and hand the parcel to the carrier or the freight driver.
4. Keep your drop-off or pickup receipt until the refund lands.

Returns arriving without an RMA cannot be matched to an order reliably and may be refused or delayed.

4. Return Shipping for Batteries

If the return is due to our error or a confirmed defect, transport is on us in both directions. For other returns you arrange and pay for ground shipping, insured for the product value; loss or damage on the way back is between you and your carrier.

5. Restocking Fees

The exact figure is stated on the RMA before you ship, never applied afterward as a surprise. The fee covers inbound freight, full inspection, capacity retest and repackaging of every returned cell.

6. Items That Cannot Be Returned

• Custom-configured packs, cut busbars and made-to-order systems.
• Products that have been installed, wired, charged in service or modified.
• Products with removed, damaged or illegible QR codes or serial labels.
• Clearance and final-sale items marked as such on the product page.

7. Inspection, Refunds and Timing

Every return is inspected and capacity-tested against its batch record on arrival, normally within 3 business days. Approved refunds go to the original payment method within 5 to 10 business days of inspection; your bank may take a few further days to post it. Original outbound shipping is refunded only when the return is due to a defect or our error. If an inspection finds the product used or incomplete, we contact you with photographs and options before doing anything else.

8. Exchanges

The fastest route is a new order for the correct item plus a standard return of the original, so stock is secured immediately. Where you prefer, we can hold the exchange against the RMA and dispatch the replacement when the return passes inspection.

9. Order Cancellations

Cancel free of charge any time before dispatch by emailing with your order number; if the order has not left, we stop it and refund in full the same day. Custom production can be cancelled only before it starts. Once goods have shipped, the return process above applies instead.

10. Damaged, Defective or Wrong Items

Report transit damage, defects on arrival or a wrong item within 48 hours of delivery with photos of the packaging, shipping label and product. We replace or refund at your choice, cover all transport, and file the carrier claim ourselves. For faults appearing after use begins, see the Warranty Policy.

11. Late or Missing Refunds

If a refund has not appeared 10 business days after our confirmation email, check with your card issuer first, then contact us with the order number and we trace the transaction with the processor the same day.
