Dongteng Lithium has redefined the capabilities of the 18650 form factor with its new NC18650-20P full-tab cylindrical cell. Engineered for high-performance power needs, this 2000mAh cell features an internal resistance of ≤9mΩ, enabling up to 15C continuous discharge and 25C pulse discharge.
Having aced ChargerLAB’s "2050" fast-charge test, it is emerging as the go-to power solution for power tools, emergency starters, and advanced energy storage systems.
The secret behind the NC18650-20P is its Full-Tab design. By drastically shortening the current conduction path, Dongteng has slashed ohmic resistance, leading to cooler operation and better energy efficiency.
The cell handles a 15C (30A) continuous discharge and a 50A burst, proving its worth under heavy loads. Charging is equally impressive: at a 2C (4A) rate, the cell goes from empty to full in just 50 minutes. With strict factory-level consistency in capacity, voltage, and resistance, it ensures balanced performance in multi-cell packs, which is critical for long-term cycle life and reliable operation.
Dongteng Lithium has successfully combined the benefits of full-tab architecture with the reliability of the 18650 size. Testing confirms the cell excels at 2C fast charging while maintaining low heat and resistance. It’s an ideal choice for developers looking to boost performance in tight spaces. As full-tab technology becomes the industry standard, cells like the NC18650-20P will continue to push power tools and energy storage systems to be smaller, faster, and more efficient.
