Rincell · INR18650RC41 · United States · 2024
Explore the Rincell RC41 lithium-ion cylindrical 18650 battery cell including capacity, mass, energy density and performance data. Compare specifications and simulate battery behaviour using validated models in the Voltt.
292Wh/kg
875W/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.

Same form factor. Nearest neighbours by energy and power density.

Rincell is a US cell developer founded in 2023, offering silicon-graphite, LMFP and sodium-ion cells built by Asian and Indian manufacturing partners. Its range includes high-energy cylindrical cells such as the RC41 18650 and RC58 21700, plus high-C-rate NMC cells, with a stated plan to move to US production. It focuses on a domestic and allied supply chain, particularly for US drone programmes.
