Detail Information

[Product Concept: The Ultimate High-Performance 21700]

The Samsung 50S is the undisputed "Super Cell" for high-drain applications. By merging a massive 5000mAh capacity with an incredible 35A-45A continuous discharge capability, the 50S eliminates the compromise between runtime and power. Specifically optimized for UAVs, high-speed drones, and professional power systems, it provides the high C-rate bursts needed for aggressive maneuvers while ensuring extended mission times. At Joyvolt, we guarantee 100% original, Grade A Samsung cells for your high-stakes projects.

[Why Samsung 50S is the Game-Changer for UAVs?]

  • Maximum Thrust-to-Weight Ratio: The 50S delivers consistent high voltage even under heavy load, ensuring your drone maintains maximum thrust throughout the flight.

  • Extended Flight Time: 5000mAh means significantly more juice per gram compared to standard LiPo or high-drain 18650 packs.

  • Stable Thermal Management: Advanced INR chemistry keeps internal resistance extremely low, reducing heat buildup during high-speed ascents or heavy-lifting tasks.

  • Superior Cycle Life: Unlike hobby-grade LiPo batteries, the 50S offers industrial-grade longevity, ensuring more flights per pack.



[Target Applications]

  • UAVs & FPV Drones: High-end aerial photography, racing drones, and long-range survey UAVs.

  • High-Performance EVs: Electric motorcycles, hyper-e-bikes, and electric skateboards.

  • Heavy-Duty Power Tools: Cordless saws, industrial grinders, and professional lighting.

  • Portable Energy Storage: Compact, high-output power stations for field engineering.


[The Joyvolt Quality Guarantee]

  • Authenticity Guaranteed: 100% original Samsung cells.

  • Technical Support: Our engineers can help you with 6S2P 6S3P pack design and BMS matching.
