INR18650-P26A — specification and pack integration
The balanced option in the Molicel 18650 power line: 2,600 mAh with 35 A maximum discharge and 6 A maximum charge, so packs gain current without dropping to 2,200 mAh.
What the numbers mean for a pack
- 2,600 mAh typical in a 18650 can, at 3.6 V nominal
- 35 A discharge ceiling — the pack design must hold the cell inside its temperature cut-off to use it
- 6.0 A maximum charge current sets the fastest realistic turnaround
- 535 Wh/L · 190 Wh/kg
- AC ≤20 mΩ (1 kHz) — the figure that decides voltage sag under load
Where it is used
- Professional cordless tools — 35 A headroom with more runtime than a 2.2 Ah cell
- E-bike and e-scooter packs with moderate peak demands
- Robotics and AGV axes with repeated torque events
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.
