Important Reminder
For DIY battery pack projects, all battery cells should be properly balanced to the same voltage before assembly.
Please make sure that installation and assembly are carried out correctly. Damage caused by incorrect wiring, improper assembly, incorrect BMS installation, charging errors, or other installation-related issues is not covered by our return or refund policy.
Before shipment, our team checks the voltage, internal resistance, appearance, and general condition of each cell.
After receiving your order, please inspect and test the battery cells within 15 days of delivery. If you notice any shipping damage, abnormal voltage, or other product-related issues, please contact us as soon as possible and provide photos or videos for verification.
Returned battery cells must remain unused and in their original condition. The terminals must be intact, with no welding marks, scratches, physical damage, or signs of installation.
Unless the issue is confirmed to be caused by the product itself or transportation, return shipping costs are the responsibility of the buyer.
Warranty
1). Warranty Period
The warranty period is 5 years from the date of successful delivery.
If the capacity of an individual battery cell falls below 80% of its initial capacity during the warranty period under normal use, please provide relevant test results, photos, or videos for verification.
After verification, we will provide an appropriate solution, which may include replacement or other after-sales support.
2). Shipping Damage or Missing Items
If any item is missing or damaged during transportation, please contact us first and provide clear photos or videos of the package and affected product.
If the shipment is lost, severely damaged, or the battery cannot be safely used due to transportation damage, we will review the situation and provide an appropriate solution, such as replacement, reshipment, or refund.
If a return is required for reasons not caused by product quality or shipping damage, the buyer is responsible for the return shipping cost.
3). Situations Not Covered by Return or Refund
Returns or refunds are generally not available in the following situations:
- Damage caused during installation or assembly, including incorrect wiring, incorrect BMS connection, assembly errors, unbalanced cells, charger failure, or improper electrical configuration.
- Damage caused by improper use, including battery swelling, welding damage, overcharging, over-discharging, or operating the battery pack without a suitable BMS.
