FAQ
1. What does 10C mean for a 2000mAh 18650 battery?
10C means the cell can discharge at 10 times its capacity. For a 2000mAh / 2Ah cell, that equals up to 20A continuous discharge. The typical nominal voltage is 3.6V / 3.7V, with a full charge voltage of 4.2V.
2. Are samples available?
Yes. Samples are available for testing. We can provide standard cells, cells with welded tabs, or small custom pack samples based on your project needs.
3. What information is needed for a quote?
Please provide the required voltage, capacity, discharge current, pack size, connector type, BMS requirements, application, and estimated order quantity. Sample testing is recommended before mass production.
