The Molicel P50B (INR21700-P50B) is a high-end 5000 mAh Li-ion cell designed for high constant discharge current applications. The perfect choice for e-bikes, e-scooters, lightweight EV battery packs where a combination of capacity + power is required. For use with BMS only.
Specifications
- Format: 21700 (unprotected cell)
- Capacity (typical): 5000 mAh
- Nominal (“standing”) voltage: 3.6 V
- Max. charging voltage: 4.20 V
- Min. discharge voltage (cut-off): 2.50 V
- Chemistry: Li-ion INR
- Discharge current: up to ~50 A constant*/ higher transient
* Actual limits depend on BMS, cooling and system design.
Key benefits
- 5000 mAh capacity with high constant current for more range and traction.
- INR chemistry is a good balance of energy density, safety and cyclicity.
- 21700 format – higher energy density than 18650 solutions.
Notes for use
- BMS (over/under voltage, current, short-circuit protection) is required.
- Spot welding (nickel/copper strips) is recommended; avoid overheating of cells during soldering.
- Charge only with Li-ion chargers according to specification; do not use damaged cells.
FAQ
Is this a protected cell (with PCB)?
No – unprotected; for BMS packages.
Can a single cell be used separately?
Only with a suitable charging/management module and guards.
