3. Optimize your contacts
Heat is often generated at bad connections, not inside the cell. panasonic ncr21700t datasheet hot
- Nominal capacity: 5000 mAh
- Nominal voltage: 3.6 V
- Charge cut-off voltage: 4.2 V
- Discharge cut-off voltage: 2.5–2.75 V (use 2.5 V for max usable capacity)
- Standard charge: 0.2 C (1 A) typical; recommended ≤0.5 C for longevity
- Max continuous discharge current: 9.8 A (typical, check pack design limits)
- Internal resistance: ~18 mΩ typical (varies by test condition)

2. Pulsed vs. Continuous Discharge
Panasonic hides the true power limitation in the pulsed data. For a 10-second pulse, the cell can handle 45A. However, the recovery time between pulses is critical. If you are pulling 35A continuously (as implied by the "max continuous" rating), you will hit the PCM (Protection Circuit Module) cut-off if used in a protected cell, or you will hit the Thermal Trip in your mod.
