Designed with advanced materials and optimized cell architecture, this battery delivers superior power output while maintaining stability and efficiency. In this article, we explore the engineering innovations behind the INR-21700-P50B and explain how its design enables reliable, high-current performance in demanding environments.
Key Specifications of the INR-21700-P50B
The INR-21700-P50B is a cutting-edge lithium-ion battery designed for applications that demand both high power and long-lasting performance. It belongs to the 21700 battery format, which is slightly larger than the more common 18650 cells, allowing it to store more energy while still delivering high power.
Key Specifications:
- Cell Type: 21700
- Nominal Voltage: 3.6V
- Typical Capacity: 5.0Ah / 18Wh
- Energy Density: 714 Wh/L, 265 Wh/kg
- Continuous Discharge Current: 60A (cutoff at 80°C)
- Low impedance of 12.8 m Ω
Compared to the predecessor, P45B, the P50B provides:
- Longer runtime.
- Better capacity retention over time.
- Slower heating which effectively doubles its cycle life up to 1400 cycles.
