1. What devices can this battery be used in?
This 21700 battery is ideal for high-drain devices such as flashlights, e-bikes, power tools, portable fans, and smart home devices. Ensure the device supports 21700 size and 3.6V input.
2. How is this battery charged?
It features a built-in Type-C charging port. Simply connect a USB-C cable to charge the battery directly—no external charger required.
3. How long does it take to fully charge?
Charging time is approximately 2 to 3 hours, depending on the charging current (recommended 5V/2A).
4. Is the battery protected?
Yes. The battery has a built-in protection circuit (PCB) for overcharge, over-discharge, overcurrent, and short-circuit protection.
5. Can I use this battery in series or parallel configurations?
For multiple-cell configurations, please consult with us to ensure electrical safety and compatibility. The built-in charging circuit may not be suitable for battery packs without adjustment.
6. What’s the difference between this and a standard 21700 cell?
Unlike standard cells, this battery features a Type-C charging port, so it doesn’t require an external charger. It is also typically slightly longer to accommodate the charging circuitry.
7. Can I order this battery with custom labels or packaging?
Yes. OEM/ODM services are available, including custom branding, capacity adjustment, and packaging design.
