BAK · N21700CG-50 · China · 2021
Explore the BAK CG-50 lithium-ion cylindrical 21700 battery cell including capacity, mass, energy density and performance data. Compare specifications and simulate battery behaviour using validated models in the Voltt.
257Wh/kg
771W/kg
Simulate and save up to 90% on cell evaluation time and cost
Run validated simulations on this cell - no test hardware, no waiting on the lab.
Top-level spec data shown here is directly from the manufacturer. Modelled and experimental metrics - including energy density, power density, TEL and discharge curves - are available through our simulation tools.
With Simulate you can configure packs, run custom dynamic power profiles, amend starting conditions and explore thousands of possible design configurations across our whole cell model database.
A precomputed example pack simulation for this cell, generated in the Voltt.
Take this cell further with the Voltt
Build a pack, run your own duty cycles and benchmark this cell against thousands of design configurations.
Other Cylindrical 21700 cells with comparable specific energy and power.
Same form factor. Nearest neighbours by energy and power density.

Chinese cylindrical cell manufacturer in Shenzhen producing 18650, 21700, 26650 and larger-format cells in NMC and LFP chemistries across energy and power grades, at high volume and consumer-grade cost. Wants customers in consumer electronics, e-mobility, power tools, energy storage and, increasingly, drones and UAVs.
