INR18650-P22S — specification and pack integration
A 2,200 mAh cell that trades capacity for current: 36 A maximum discharge at an 80 °C cut-off with 3.0 V cut-off, and charging allowed down to -20 °C.
What the numbers mean for a pack
- 2,200 mAh typical in a 18650 can, at 3.6 V nominal
- 36 A discharge ceiling — the pack design must hold the cell inside its temperature cut-off to use it
- 4.0 A maximum charge current sets the fastest realistic turnaround
- 403 Wh/L · 147 Wh/kg
- AC 10 mΩ (30% SOC) · DC 22 mΩ (50% SOC) — the figure that decides voltage sag under load
Where it is used
- Cold-chain and outdoor equipment — charge window starts at -20 °C rather than 0 °C
- High-current handheld tools where burst current outweighs runtime
- Starter and crank-assist packs that need short, heavy pulses
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.
