INR21700-P42A — célula de íon-lítio 21700

Molicel INR21700-P42A: 4,200 mAh typical (4,000 mAh minimum), 3.6 V nominal, 45 A discharge. The long-running 21700 workhorse: 4,200 mAh with 45 A continuous discharge. Charge window is narrower than newer parts — 0 °C to 45 °C — so packs need thermal management on the charge side.

INR21700-P42A — specification and pack integration

The long-running 21700 workhorse: 4,200 mAh with 45 A continuous discharge. Charge window is narrower than newer parts — 0 °C to 45 °C — so packs need thermal management on the charge side.

What the numbers mean for a pack

  • 4,200 mAh typical in a 21700 can, at 3.6 V nominal
  • 45 A discharge ceiling — the pack design must hold the cell inside its temperature cut-off to use it
  • 615 Wh/L · 230 Wh/kg
  • AC 10 mΩ (1 kHz) · DC 16 mΩ (10 A/1 s) — the figure that decides voltage sag under load

Where it is used

  • E-mobility packs where 45 A continuous per cell is the design point
  • Power tool packs moving from 18650 to 21700 for current headroom
  • Industrial UPS and backup 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.
