The Skilhunt BL-265 is a high-capacity, protected 21700 rechargeable lithium-ion battery designed for compatible high-performance flashlights and other electronic devices.

Featuring a 6500mAh typical capacity, 6350mAh rated capacity, and 19A continuous discharge current, the BL-265 delivers an excellent combination of extended runtime, reliable power delivery, and built-in battery protection.

With a maximum discharge current of 25A, a nominal voltage of 3.6V, and an integrated protection circuit, the BL-265 is an ideal choice for compatible flashlights that require a high-capacity protected 21700 battery.

Important: This is a protected button-top 21700 battery measuring approximately 75mm in length. Please verify device compatibility before purchasing.

6500mAh High Capacity for Extended Runtime

The Skilhunt BL-265 offers a 6500mAh typical capacity and 6350mAh rated capacity, providing substantial energy storage for demanding flashlight applications.

With approximately 23.4Wh of nominal energy, this battery is designed to support longer operating times compared with lower-capacity 21700 batteries under similar conditions.

Its high-capacity design makes it especially suitable for users who prioritize extended runtime during outdoor adventures, camping, hiking, nighttime activities, and everyday flashlight use.

Actual runtime depends on the flashlight's power consumption, brightness setting, operating temperature, and battery condition.

19A Continuous Discharge and 25A Maximum Discharge

The BL-265 is designed to provide reliable current delivery for compatible high-performance flashlights.

Its discharge specifications include:

• Continuous Discharge Current: 19A

• Maximum Discharge Current: 25A

• Discharge Cutoff Voltage: 2.50V

The 19A continuous discharge rating supports demanding applications requiring sustained current delivery.

The 25A maximum discharge rating represents the battery's specified maximum discharge capability and should not be interpreted as a 25A continuous discharge rating.

Important: High-current operation can generate significant heat. Battery temperature, operating conditions, and the flashlight's electrical requirements must be considered.

Repeated high-current discharge may reduce battery lifespan.

Built-In Protection Circuit

Unlike unprotected 21700 lithium-ion cells, the Skilhunt BL-265 features an integrated protection circuit designed to help prevent damage caused by abnormal electrical conditions.

The battery incorporates multiple safety features, including:

• Overcharge protection

• Over-discharge protection

• Overcurrent protection

• Short-circuit protection

• Pressure relief vent

• Microporous separator

Protection Specifications

The integrated protection circuit provides an additional layer of electrical protection, but proper charging, handling, and storage are still essential.

Note: The 47 ± 5A overcurrent protection threshold is a protection-circuit trigger specification, not the battery's recommended operating or continuous discharge current.

Rechargeable 21700 Li-ion Battery

The BL-265 uses a nominal voltage of 3.6V and supports charging up to 4.20V.

Its charging specifications include:

• Recommended Charging Current: 2A

• Maximum Charging Current: 6A

• Full Charge Voltage: 4.20V

For everyday use, a compatible lithium-ion charger operating at the recommended 2A charging current is a practical choice.

The battery does not have a built-in USB-C charging port. It should be charged using a compatible external charger or a flashlight with an appropriate integrated lithium-ion charging system.

Protected Button-Top Design

The Skilhunt BL-265 features a raised positive terminal and an integrated protection circuit.

Because of the protection circuitry, the battery is longer than many standard unprotected 21700 cells.

Its physical dimensions are approximately:

• Length: 75mm (2.95 inches)

• Diameter: 21.9mm (0.86 inches)

• Weight: 77g (2.72 oz)

Battery Compatibility Notice: The BL-265 is a protected button-top 21700 battery. It may not fit flashlights designed exclusively for shorter, unprotected flat-top 21700 cells.

Before purchasing, confirm that your device supports protected 21700 batteries with a length of approximately 75mm and a diameter of 21.9mm.

Never force the battery into an incompatible battery compartment.
