FAQ
🙋‍♂️ Q1: What must be done before assembling a DIY battery pack?
For DIY battery packs, you must get the cells balanced (ensuring the same voltage) before assembly. Please note that incorrect assembly or issues caused by lack of assembly knowledge are not eligible for refunds.
🙋‍♂️ Q2: How does the testing and inspection process work before shipping?
Professionals detect the voltage, internal resistance, appearance, and other key parameters of every battery before shipment. We ensure that each single battery is in good condition. You can test the cells within 15 days of arrival to verify their condition.
🙋‍♂️ Q3: What is the warranty period and how do I make a claim?
The warranty period is 5 years from the date of successful delivery. If a single battery's capacity drops to less than 80% of its initial capacity, please take test pictures or a video and send them to us to receive a replacement or alternative solution.
🙋‍♂️ Q4: What is the policy for shipping damage or missing items?
Please contact us first and send pictures or videos to check the issue. In cases of lost cargo or if the battery is damaged and cannot be safely used, we will coordinate to resend, replace, or refund the product cost. For returns, the buyer is responsible for shipping costs.
🙋‍♂️ Q5: Which situations are excluded from returns and refunds?
We do not provide returns or refunds for:
1. Problems arising during or after assembly (e.g., protection board connected incorrectly leading to battery damage, charger failure, assembly errors, or unbalanced assembly).
2. Damage caused by charging a battery pack without a protective BMS, or physical modifications like welding and cell bulging.
🙋‍♂️ Q6: Do these batteries come with built-in protection?
These products are prototype batteries without built-in protection boards. You must purchase and configure a matching BMS (Battery Management System) before using them. Please consult us for advice on matching components before ordering.
