Lab-validated simulation of the Samsung SDI 50U 21700 battery cell for eVTOL and electric aviation, covering rate-dependent discharge, constant power loading, pulse capability, and a full 800 V pack mission cycle.

Lab-validated simulation of the LG INR21700H52A 21700 cell for eVTOL and electric aviation, covering rate-dependent discharge, constant power loading, pulse capability, and a full 800 V pack mission cycle.

Simulated discharge, constant power, pulse power, and eVTOL mission data for the Reliance RS50 (INR21700-RS50). See how this 5 Ah, 14C cell performs in a 222s16p 800V pack across a full passenger flight cycle.

Tesla's tabless Model Y cell stores five times the energy of a standard 21700 and charges fast enough for automotive duty. But bigger is not always better. We pulled cells from a Munro teardown, put them through the About:Energy lab, and the data shows what the tabless design actually changes for performance, thermal behaviour and cell longevity.
