Reliance · INR21700-RS50 · China · 2024
Explore the Reliance RS50 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.
269Wh/kg
3761W/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.

Jiangsu Reliance Energy Tech is a Chinese cylindrical cell manufacturer founded in 2021 in Changzhou, specialising in tabless large cylindrical cells. Its production base targets 14 to 16 GWh in Phase 1, with a Phase 2 expansion planned. It produces tabless 21700 and 46-series cells for high energy density and fast charging, with an all-tabless focus aimed at UAV, eVTOL, robotics, power tools and e-mobility.
