FAQ
What preparation is required before assembling a DIY battery pack?
DIY battery packs must have the cells balanced (same voltage) before assembly. Returns or refunds are not accepted for issues resulting from wrong assembly or lack of assembly knowledge.
How are the batteries tested before shipment, and what is the return policy?
Professionals detect voltage, resistance, appearance, and other parameters before shipment to ensure single cell quality. You can test the cells within 15 days of arrival. Returns are only accepted if the battery is unused (electrode intact, no welding, no wear, and appearance is good). Buyers are responsible for return shipping costs.
What is the warranty period and terms?
The warranty period is 5 years from the date of successful delivery. If a single battery capacity falls below 80% of its initial capacity, please provide test pictures or videos, and we will replace it or offer a satisfactory solution.
What happens if a battery is lost or damaged during shipping?
Please contact us first and send pictures or videos to check. In the case of lost cargo or if the battery is damaged and unusable, we will communicate with the buyer to resend, replace, or refund the product cost.
Which situations are excluded from refunds and returns?
We do not provide returns or refunds for: 1) Problems arising during or after the assembly process (e.g., protection board connected to the wrong wire leading to battery damage, charger failure, assembly error, or unbalanced assembly). 2) Damage caused by charging without a protective BMS, or battery bulge/welding.
Do the cells come with a protection board (BMS)?
No, these products are prototype cells without protection boards. You need to purchase a matching BMS separately to manage and protect the battery pack. Please consult us for details.
