Frequently Asked Questions (FAQ)
1) What happens if the shipping is damaged or missing items?
Please contact us with pictures or videos. In case of loss or severe damage that prevents use, we will communicate regarding resending, replacement, or refunding product costs.
2) Do you test each battery before shipping?
Yes. Capacity Test: Less than 2% margin of error. Voltage deviation: less than 0.01V. Resistance deviation: less than 0.05mΩ.
3) Do the batteries come with busbars and bolts?
The cells come with Bus bars and Bolts or studs for free. Typically, each battery includes 1 busbar and 2 bolts/studs.
4) What situations are not eligible for return or refund?
Damage caused by incorrect assembly (e.g., wrong BMS wiring), charger failure, unbalanced assembly, or battery bulging due to charging without BMS protection.
5) How do I place an order for prototype cells?
We accept trade assurance orders online. For Ready to Ship (RTS) products, you can pay directly if shipping costs are clear. Please ensure you have a protection board (BMS) as these are prototype cells.
6) What is the requirement for DIY battery pack assembly?
Cells must be balanced (same voltage) before assembly. Once arrived, you have 15 days to test the cells. Returns are only accepted if electrodes are intact, no welding, and no wear.
