* Nota: Public sources show different revisions/test conditions for some specifications, particularly discharge current, dimensions, cycle-life definition and temperature limits. For your final independent-site datasheet, I recommend replacing these values with the latest original manufacturer datasheet for your actual RS50 batch. Por ejemplo, one public manufacturer-derived source lists 70A continuous discharge with an 80°C cutoff, while another technical database evaluates the cell at 40A continuous.

1. 5000mAh High Capacity

The 5Ah nominal capacity provides approximately 18Wh of energy per cell, helping battery manufacturers achieve longer runtime without increasing the number of cells excessively.

Beneficios para el cliente:

  • Longer operating time
  • Higher pack energy
  • Fewer cells for certain pack configurations
  • Better space utilization

2. High-Power Discharge Capability

RS50 is designed for high-drain applications where conventional energy-oriented cells may not provide sufficient power.

Public sources report high continuous-current capability, with the exact allowable current dependent on thermal conditions and the applicable manufacturer specification.

Beneficios para el cliente:

  • Strong acceleration response
  • Stable high-load operation
  • Reduced voltage sag
  • Suitable for demanding power systems

3. Alta densidad de energía 21700 Format

El 21700 cylindrical format provides a useful balance between capacity, power and pack integration.

Beneficios para el cliente:

  • Higher capacity per cell
  • Compact battery pack design
  • Efficient use of internal pack space
  • Suitable for high-performance battery systems

The RS50 is reported at approximately 269Wh/kg gravimetric energy density in public cell databases.


4. Designed for High-Drain Applications

The RS50 is particularly suitable when equipment requires both energy and high current.

Recommended applications:

  • E-bike
  • Light EV
  • herramientas eléctricas
  • Robotics
  • Industrial equipment
  • High-power battery packs
  • Custom lithium battery systems

5. Flexible Battery Pack Configuration

The cell can be connected in series and parallel configurations to create different battery pack specifications.

Por ejemplo:

10S2P → 36V-class battery pack

13S2P → 48V-class battery pack

14S4P → high-capacity 48V-class battery pack

The final configuration should be selected according to the required voltage, capacidad, current, BMS and thermal design.


6. Suitable for Professional OEM Battery Development

The RS50 can be integrated into customized battery packs for equipment manufacturers and battery-pack companies.

OEM Support:

  • Battery pack design
  • Series/parallel configuration
  • BMS integration
  • Selección de conector
  • Structural design
  • Custom labeling
  • Custom packaging
