Share This:
The LINKDATA INR21700S-60P is a high-performance 21700 lithium-ion battery cell designed to combine high capacity with exceptional discharge capability. With a typical capacity of 6000mAh, a nominal voltage of 3.6V, and a maximum continuous discharge current of 60A under specified thermal conditions, it is engineered for demanding high-power applications.
Featuring low internal resistance and support for high-current discharge, the INR21700S-60P offers an impressive combination of energy storage and power delivery. It is suitable for compatible high-drain equipment and professionally designed battery packs that require both substantial capacity and high current output.
6000mAh High Capacity
With a typical capacity of 6000mAh and a minimum specified capacity of 5880mAh, the INR21700S-60P provides substantial energy storage in a standard 21700 cylindrical cell format.
Its rated energy is approximately 21.6Wh, making it suitable for applications that require a combination of extended operating time and high power output.
Up to 60A Continuous Discharge
The INR21700S-60P is designed for demanding high-current applications.
-
Maximum continuous discharge: 60A under the manufacturer's specified thermal conditions
-
Maximum pulse discharge: 110A for up to 10 seconds under specified test conditions
-
AC internal resistance: Less than 4.5mΩ
The manufacturer specifies the 60A continuous discharge rating with an 80°C cell-temperature cutoff. Actual current capability depends on temperature, cooling, operating conditions, and the design of the battery system.
The 110A pulse rating applies only under the manufacturer's specified test conditions and should not be treated as a continuous operating current.
Low Internal Resistance for High-Power Applications
The cell's specified AC internal resistance of less than 4.5mΩ supports efficient high-current delivery and helps limit resistive losses.
This characteristic makes the INR21700S-60P suitable for appropriately engineered high-power battery systems where both capacity and current capability are important.
Charging Specifications
The INR21700S-60P uses a standard lithium-ion charging profile with a maximum charge voltage of 4.2V.
-
Standard charging current: 6A
-
Maximum charging current: 8A
-
Standard charging time: Less than 2 hours under specified test conditions
-
End-of-charge voltage: 4.2V
-
Discharge cutoff voltage: 2.5V
Use a compatible lithium-ion charger or properly designed battery management system that follows the manufacturer's charging specifications. Do not exceed the specified charge voltage or current.
Designed for High-Drain Battery Systems
The LINKDATA INR21700S-60P is intended for applications that require high current delivery and substantial energy capacity, including compatible high-power equipment and professionally engineered lithium-ion battery packs.
For flashlight use, verify that the flashlight supports the 21700 battery format, the cell's length and diameter, its flat-top terminal, and the required discharge current.
This is an industrial battery cell rather than a universal replacement for every 21700 flashlight battery.

Important Battery Safety Information
The LINKDATA INR21700S-60P is an unprotected lithium-ion cell. It does not have an integrated protection circuit.
-
Confirm that the device or battery system is compatible with an unprotected 21700 cell.
-
Use a compatible lithium-ion charger with appropriate voltage and current limits.
-
Prevent short circuits and contact with conductive objects.
-
Do not use damaged, dented, or improperly insulated cells.
-
Do not exceed the manufacturer's charging, discharge, or temperature limits.
-
Battery packs using multiple cells require appropriate engineering, cell matching, and protection circuitry.
This cell is intended for users and applications that can safely accommodate an unprotected high-discharge lithium-ion battery.
