FAQ
What preparation is required before assembling a DIY battery pack?
DIY battery packs must have the cells balanced (same voltage) before assembly. Please note that return or refund requests are not accepted for wrong assembly or if you do not know how to assemble.
What testing is performed before the batteries are shipped?
Professionals detect voltage, resistance, appearance, and other parameters before every shipment. Upon arrival, you can test the cells within 15 days. After this period, it is assumed the batteries are in good order.
How long is the warranty and what does it cover?
The warranty period is 5 years from the date of successful delivery. If the single battery capacity falls below 80% of its initial capacity, please provide test pictures or video to us, and we will replace it or give a satisfied solution.
What should I do if my shipping is damaged or missing items?
Please contact us first, then send us pictures or video to check. In case of lost cargo or severe damage that makes the battery unusable, we will communicate with the buyer to either resend, replace, or refund the product cost. Return shipping costs are paid by the buyer.
Under what conditions are returns or refunds not provided?
We do not provide returns or refunds for:
1. Issues occurring during or after assembly, such as a protection board connected incorrectly causing battery damage, charger failure, assembly errors, or unbalanced assembly.
2. Damage caused by charging a battery pack without a protective BMS, resulting in bulging or welding.
Do these batteries come with built-in protection boards?
These products are prototype batteries without protection boards. You will need to purchase a matching protection board (BMS) separately. Please consult us for details before placing your order.
