❓ FAQ – 18650 2600mAh 3C Lithium Ion Battery

1. What does “3C discharge” mean?

“3C” refers to a discharge rate three times the battery’s capacity. For a 2600mAh cell, 3C equals 7.8A continuous current output.

2. Can I use this battery in a custom battery pack?

Yes! These 18650 cells are ideal for assembling custom battery packs. We offer spot welding, BMS integration, and wiring harness solutions.

3. Is this battery protected or unprotected?

This is an unprotected cell intended for battery pack integration with external PCM/BMS. If you need protected cells, we also supply versions with built-in safety circuits.

4. How should I store the battery long-term?

Store between 20–25°C in a dry environment, ideally at 40–60% state of charge. Avoid high humidity and direct sunlight.

5. Do you provide test reports or datasheets?

Yes. Technical datasheets, UN38.3 test reports, and MSDS documentation are available upon request. Contact us for more info.
