V4Smart · V21700 UHP-26 · Germany · 2025
Explore the V4Smart UHP-26 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.
140Wh/kg
5441W/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.

Same form factor. Nearest neighbours by energy and power density.
V4Smart is a German manufacturer of ultra-high-performance lithium-ion cylindrical cells, majority owned by Porsche AG, producing 21700 tabless cells in mass production scale (IATF 16949 certified). The first generation booster cells are designed for short, intense power peaks, already used in Porsche 911 GTS/TurboS. The second generation cells are upgraded in energy density while keeping extreme power performance.
