To avoid a "hot" battery becoming a safety hazard, the Panasonic NCR21700T requires proper management in a pack design:
Up to 1.0C (approx. 4.8A) under controlled thermal conditions. Higher charging currents will accelerate cell degradation. Discharge Performance and Current Limits
Buy an infrared thermometer. If the metal can exceeds , stop discharging. The datasheet explicitly states that exceeding 60°C voids the warranty and accelerates aging.
The Panasonic NCR21700T (often cited as having a 5000mAh capacity) represents a shift towards high-energy-density cells that still maintain decent discharge capabilities. Key Data Sheet Highlights NCR21700T Size: 21700 (21mm Diameter x 70mm Length) Nominal Capacity: 5000mAh (Typical) / 4850mAh (Minimum) Nominal Voltage: 3.6V Maximum Charging Voltage: 4.2V panasonic ncr21700t datasheet hot
Optimized for steady currents up to 10A to 15A without active cooling.
Let’s crack open the official Panasonic NCR21700T datasheet and separate the scorching performance from the literal heat.
