Frequently Asked Questions

1. Are the battery cells brand new and Grade A?
Yes, we only supply 100% original Grade A brand new cells with intact QR codes from leading manufacturers like EV, CATL, and CALB.
2. Do the batteries come with busbars and bolts?
Yes, each battery includes one set of busbars and two bolts/studs for free. If you require additional sets or specific sizes, please let us know.
3. What is the standard testing procedure before shipping?
Every cell undergoes rigorous testing. We ensure the capacity margin of error is less than 2%, voltage deviation is under 0.01V, and internal resistance deviation is under 0.05mΩ.
4. Do I need to balance the cells before assembling a DIY pack?
Yes, for DIY assembly, cells must be balanced (same voltage) beforehand. We recommend using a high-quality BMS (Battery Management System) to protect the pack.
5. What is the return and warranty policy?
We provide a 1-year warranty. Returns are accepted within 15 days if the cells are unused (intact electrodes, no welding, no wear). Buyers are responsible for return shipping fees.
6. How are the batteries protected during international shipping?
Batteries are packed in 5-layer corrugated cartons with high-hardness custom sponges. We use insulation tape on terminals and follow strict dangerous goods transport protocols.
