EVE 50PL 21700 5000 mAh 125A Battery

4. Product Description

The EVE 50PL 21700 5000mAh 125A Battery is a rechargeable lithium-ion cell developed for applications that require high energy capacity and high power delivery. Its 21700 cylindrical format provides a nominal voltage of 3.6V and a capacity of 5000mAh, making it useful for designing compact, high-performance battery systems.

With approximately 18Wh of nominal energy per cell, the EVE 50PL can be used in appropriately engineered battery packs for power tools, electric mobility systems, and other high-current applications. For demanding loads, the cell's permitted discharge current must be determined from the correct manufacturer datasheet, considering cell temperature and operating conditions.

Features

• 5000mAh capacity: Provides 5Ah of nominal capacity for suitable battery-pack designs.

• 3.6V nominal voltage: Designed for use in compatible lithium-ion power systems.

• 21700 cylindrical format: Approximately 21.15mm in diameter and 70.15mm in height.

• High-power cell design: Intended for applications requiring substantial current delivery.

• Approximately 18Wh energy: Nominal energy based on voltage and capacity.

• Flat-top construction: Suitable for compatible battery holders or professionally assembled packs.

• Versatile applications: Can support custom battery systems when the cell, wiring, protection, and load are properly matched.

Applications

• Custom lithium-ion battery packs

• High-power electric tools

• Electric bicycles and scooters, where the complete pack is properly engineered

• Robotics and high-current electronics

• Portable power systems

• Other battery-powered equipment compatible with 21700 cells

How to Use

1. Confirm that the equipment or battery-pack design supports a 21700 lithium-ion cell.

2. Use a compatible charger with a proper CC/CV charging profile and a 4.20V cell-voltage limit.

3. Install appropriate battery-management and protection circuitry for the intended series/parallel configuration.

4. Ensure the cell connections, conductors, terminals, and fusing are rated for the expected current.

5. Monitor cell temperature and voltage under load.

6. For multi-cell packs, use a suitable battery management system (BMS) with cell monitoring and protection.

Important Notes

• Verify the 125A claim: The maximum permitted continuous discharge depends on the exact cell revision and manufacturer documentation. Do not design a system around 125A without confirming that rating.

• This is typically an unprotected lithium-ion cell. It does not replace a BMS or other required safety circuitry.

• Do not exceed 4.20V charging voltage or discharge below the specified cutoff.

• Never short-circuit, puncture, crush, or reverse-polarity-connect the cell.

• High-current applications can produce substantial heat. Appropriate thermal monitoring, current limiting, insulation, and fusing are essential.

• Avoid soldering directly to the cell unless the manufacturer explicitly permits the method; use suitable cell-connection techniques.

• Use only genuine cells from a reliable source, and do not use damaged, swollen, or overheated cells.
