The 21700 battery operates at a nominal voltage of 3. This voltage range aligns with industry standards for lithium-ion batteries, ensuring compatibility with various devices and systems. . Lithium-ion batteries have revolutionized portable power solutions, and two popular cylindrical cell formats stand out: the 18650 and 21700. Their proper name is a “21700 cell”. 7v and has between 3000 mAh and 5100 mAh (mili-amp-hours). It was developed as an improvement over the 18650 battery, offering higher capacity, better energy density, and improved efficiency, making it ideal for. . They're slightly bigger than the classic 18650 cells, but that extra space means a nice jump in capacity and discharge performance. From my own experience, the biggest difference is that devices simply last longer without adding bulky weight.

The 21700 battery supports a discharge rate of 3.75C, which means a 5000 mAh cell can output a current of 18.75A. This high discharge rate feature makes it perfectly suitable for high-power consumption devices such as angle grinders and heavy-duty power tool motors that require sudden bursts of high power without voltage drop.
Discharge Rates With discharge rates often exceeding 10A (and up to 35A for high-performance variants), 21700 cells are suitable for demanding applications such as drones, high-performance flashlights, and vaping devices.
The circuit is embedded in the cell packaging (battery casing) that protects the cell from “over charge”, heat or “over discharge”, over current and short circuit. A 21700 protected battery is safer than an 21700 unprotected battery (less likely to overheat, burst or start on fire).
Max Discharge Current: 21700 batteries can typically handle a discharge current of 10A to 30A, making them suitable for high-power applications.
