Description
EVE INR21700-50E is a 21700-format lithium-ion cell with a capacity of 5000 mAh, designed for applications where a large amount of energy and a high discharge current matter. The combination of 5000 mAh capacity and a continuous current of up to 15 A makes it a good choice for building battery packs, energy storage systems, power banks and powering electronic devices.
Why EVE INR21700-50E?
- High capacity – 5000 mAh. The 21700 format holds much more energy than popular 18650 cells, so a pack can be smaller or run longer on a single charge.
- High discharge current – up to 15 A. The cell copes with demanding loads such as tools, inverters, e-bikes and electric scooters.
- Flat positive terminal (flat top). Convenient for spot-welding with nickel strips when assembling packs.
- 21700 format (21.15 × 70.15 mm). A popular size with holders, cell brackets and ready-made pack designs available.

Important safety information
The cell is sold without a built-in protection circuit. When building packs, use a BMS matched to the number of cells and operating currents, and charge them according to the manufacturer’s datasheet. Do not discharge the cell below the minimum voltage, short the terminals or expose the cell to mechanical damage. Packs should be assembled by a person with the appropriate knowledge.
