❓ FAQ – 18650 2000mAh 3.7V 15C Lithium Ion Battery

1. What does “15C” mean in battery terms?

“15C” refers to the maximum continuous discharge rate of 15 times the battery’s capacity.
For a 2000mAh battery, 15C = 30A continuous discharge, ideal for high-power applications.

2. Is this battery safe for DIY or commercial packs?

Yes, but due to its high current rating, this unprotected cell must be used with a reliable BMS or protection circuit in packs. We also offer protected or PCM-integrated versions upon request.

3. What charger should I use for this battery?

Use a Li-ion charger rated for 3.7V cells. Recommended charging at 0.5C–1C (1000–2000mA). Avoid overcharging beyond 4.2V.

4. Can I buy in bulk with custom options?

Absolutely. We support bulk OEM/ODM orders with custom tab welding, pack configuration, shrink wrapping, labeling, and more. Lead time:

• Samples: 3–5 business days

• Bulk production: 10–15 business days

5. What is the expected cycle life of this battery?

With proper charging and discharging protocols, you can expect to 500+ cycles, retaining ≥80% capacity.
