Acerca de Molicel INR21700-P50B 21700 Li-ion Cell 5,000 mAh 60 A
The P50B is Molicel's flagship 21700 and the cell the company markets under its own application headings: hyper EVs and racing sports cars, eVTOLs, two-wheeled motorcycle racing, heavy-lift drones and backup battery units. Molicel quotes 265 Wh/kg and 714 Wh/L, 60 A discharge, 5 C charging, and 1,400 cycles at 100 W discharge — roughly double the P45B.
Why pack builders specify it
- 60 A discharge rating with 12.8 mΩ impedance, so peak power arrives with less heat
- 5 C fast charge from a graphite anode engineered for the rate
- 1,400 cycles at 100 W discharge, about double the P45B in the same test
- Peak power of 413 W at 45 C and 238 W at -10 C on Molicel's 10-second tables
Typical applications
- eVTOL and electric aviation – Molicel targets the vertical take-off and landing segment where power is required in short, repeated bursts
- Hyper EVs and racing – More than 10 C discharge capability for extreme short-duration output
- Heavy-lift drones – High power-to-energy ratio where every gram of cell mass counts
- Data centre backup battery units – Molicel lists the P-series for BBU and UPS service with rack-level monitoring
- Racing motorcycles – High current with fast recharge between sessions
Where it fits
This is the cell for programmes where power density and recharge time are both hard requirements — aviation, motorsport, BBU. For energy-first packs discharging below 1 °C, a Samsung 50E or 53G costs less and stores the same or more energy.
Charging and pack integration
Charge CC-CV to 4.2 V within the current limits listed 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.
Certifications and documentation
UN38.3, MSDS, IEC 62133-2, UL 1642, CE, RoHS, REACH. UN38.3 test summary, MSDS and the cell specification are available on request.
