Flat-top 21700 cell for high-drain devices
These EVE 50E lithium-ion cells measure 21mm by 70mm and deliver 5000mAh at 3.7V. They are built for flashlights, power-tool packs and other gear that demands a flat-top 21700 form factor. The two-pack suits users who need a matched pair for series or parallel configurations.
15A continuous discharge rating
The single figure that decides fit is the 15A maximum continuous discharge. Devices drawing more current will over-stress the cell, while lighter loads will not benefit from the high-drain design. Verify your equipment’s peak draw before purchasing.
Simple drop-in with polarity care
Installation is a straight swap: insert the flat-top ends according to the device markings. The only common error is confusing flat-top with button-top terminals, which prevents contact in many torch bodies. No soldering or tab welding is required for standard battery compartments.

Questions about this item
What does the 5000mAh capacity mean for runtime in a real device?
The 5000mAh rating means the cell can supply 5000 milliamps for one hour, so a device drawing 1A would run for about five hours before the voltage drops to the cut-off point.
How does the 15A continuous discharge limit affect what I can power?
The 15A maximum continuous discharge caps the current the cell can safely deliver, so any load drawing more than 15A will overheat the battery or trigger its protection circuit.
Will the 21mm by 70mm flat-top cells fit my 21700 device?
These cells measure 21mm in diameter and 70mm in length with a flat positive terminal, matching the standard 21700 form factor used in many flashlights and power tools.
