INR21700-P50S — celda de ion-litio 21700
Molicel INR21700-P50S: 5,000 mAh typical (4,900 mAh minimum), 3.6 V nominal, 60 A discharge. 5,000 mAh at 60 A standard discharge and 250 W maximum at an 83 °C cut-off — the highest power figure in the 21700 line, with a 4,900 mAh minimum rather than a typical-only rating.

INR21700-P50S — specification and pack integration
5,000 mAh at 60 A standard discharge and 250 W maximum at an 83 °C cut-off — the highest power figure in the 21700 line, with a 4,900 mAh minimum rather than a typical-only rating.
What the numbers mean for a pack
- 5,000 mAh typical in a 21700 can, at 3.6 V nominal
- 60 A discharge ceiling — the pack design must hold the cell inside its temperature cut-off to use it
- 25 A maximum charge current sets the fastest realistic turnaround
- 714 Wh/L · 260 Wh/kg
- AC 6 mΩ (30% SOC) · DC 13 mΩ (50% SOC) — the figure that decides voltage sag under load
Where it is used
- Backup battery units (BBU) for data centres and AI compute racks
- eVTOL and heavy-lift drone packs where both energy and burst power bind
- Hyper-EV and motorsport traction modules
Integration notes
Charge CC-CV to 4.2 V within the current limits above and stop discharge at 2.5 V. These are unprotected industrial cells: a BMS or protection circuit is required, interconnects must be resistance or laser welded rather than soldered, and cells of different model, batch or state of charge must not be mixed in one pack. Charging below 0 °C is not permitted unless the pack implements a low-temperature charge strategy.
