INR21700-M58T — 21700 lithium-ion cell
LG Energy Solution INR21700-M58T: 5,650 mAh typical, 3.59 V nominal, 12.5 A discharge. The highest-capacity cell in this line at 5,650 mAh, with a 12.5 A ceiling — an energy-first part for packs that never see high C-rates.

INR21700-M58T — specification and pack integration
The highest-capacity cell in this line at 5,650 mAh, with a 12.5 A ceiling — an energy-first part for packs that never see high C-rates.
What the numbers mean for a pack
- 5,650 mAh typical in a 21700 can, at 3.59 V nominal
- 12.5 A discharge ceiling — the pack design must hold the cell inside its temperature cut-off to use it
- ≤15 mΩ — the figure that decides voltage sag under load
Where it is used
- Stationary storage where floor space and cell count dominate cost
- Long-endurance portable equipment
- Low-rate backup and standby packs
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.
