Context: Rincell's RC50T targets the opposite end of the power-energy trade-off
Rincell says its RC50T tabless 21700 cell provides 100 A continuous and 150 A pulse discharge with energy density above 265 Wh/kg and 3-4 mΩ internal resistance. These are manufacturer specifications, not independent test results.

The contrast with high-specific-energy cells is useful for builders: multicopter peak power and fixed-wing endurance can favor very different cell designs.
Bench-test sag and temperature with the pack topology and duty cycle you will actually fly. Cell-level current ratings do not automatically become safe pack-level limits.
