DONG-TENG has leveled up its battery game with the new NC18650-25P. This 2.5Ah, 3.7V cell is built for those who need speed without sacrificing reliability. Its standout feature is an ultra-low internal resistance of just 4.92 mΩ—nearly half the industry standard—ensuring cooler operation and higher efficiency.
In real-world testing, the cell reaches full capacity in 5h 24m at 0.2C and 2h 32m at 0.5C, while high-rate performance is even more impressive, hitting 100% in 1 hour and 33 minutes at 1C and just 1 hour and 14 minutes at 1.6C. Impressively, the cell achieves a 50% charge in just 19 minutes at 1.6C, earning a passing grade from ChargerLAB’s "2050" fast-charge metrics.
The NC18650-25P is as durable as it is fast. With a steel-cased design, a flat-top alloy positive terminal with integrated safety vents, and an anodized negative terminal, it’s built to last. Standard dimensions (65.4mm x 18.1mm) ensure it fits perfectly into most devices and small storage modules.
The DONG-TENG NC18650-25P proves that you don’t have to pay a premium for high-quality fast charging. Whether you need efficiency for daily use or rapid top-ups on the go, this cell stands out as one of the best value-for-money options currently on the 18650 market.
