What is the discharge rate of a 21700 battery?
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.
What is a 21700 cell used for?
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.
What is a 21700 protected battery?
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).
How much charge can a 21700 battery handle?
Max Discharge Current: 21700 batteries can typically handle a discharge current of 10A to 30A, making them suitable for high-power applications.
