21700G/68E 6500mAh 3.6V Lithium-ion Rechargeable Cell for Custom Battery Pack OEM ODM Applications
The 21700G/68E is a 6500mAh lithium-ion rechargeable cell developed for customized battery pack design, OEM/ODM projects, and professional rechargeable battery applications. Combining a 3.6V nominal voltage with the 21700 cylindrical format, it provides battery pack designers with a flexible foundation for developing different voltage and capacity configurations.
The cell features a 0.7C charge rate, 2C discharge rate, and internal resistance of ≤19mΩ. Its 1000-cycle rated life makes it suitable for rechargeable battery projects requiring repeated charge and discharge operation.
With dimensions of 70.95 × 21.65mm and a weight of 75g, the 21700G/68E can be incorporated into customized series-parallel battery configurations. Battery pack manufacturers can select the appropriate number of cells according to the required voltage, capacity, physical dimensions, and application requirements.
The 21700G/68E can be evaluated for prototype development, sample production, battery pack testing, and OEM/ODM projects where customers require a 6500mAh 21700 lithium-ion rechargeable cell.
