Frequently Asked Questions

1. What should I do before assembling a DIY battery pack?
DIY battery cells must be balanced (same voltage) before assembly. We ensure single battery quality before shipment, but proper assembly and BMS connection are the user's responsibility.
2. How many cells do I need for my specific system voltage?
For a 12V system, you need 4 pieces; for a 24V system, 8 pieces; and for a 48V system, 16 pieces. These are suitable for solar energy storage and backup power.
3. Are the batteries tested before shipping?
Yes, every battery undergoes capacity testing (less than 2% margin of error), voltage deviation checks (less than 0.01V), and internal resistance testing (deviation less than 0.05mΩ).
4. Do the batteries come with necessary hardware?
Yes, cells include busbars and bolts/studs for free. Typically, each battery comes with 1 busbar and 2 bolts or studs.
5. What is the policy for shipping damage or loss?
If items are missing or damaged during transit, please provide photos or videos immediately. We will communicate to arrange a replacement or refund for the product cost.
6. Under what conditions are returns not accepted?
Returns are not accepted if damage occurs during assembly (e.g., wrong BMS wiring, charger failure, or unbalanced assembly) or if the battery shows signs of use like welding or wear.
