There’s evidence to that. I tested the two e07x (ffl351a and 519a) on various batteries (Samsung 50S, 30 and 40T, P42A, and one of the really spicy ones i got with the NS59V1).
The hard limit seemed to be around 23-24 amps. I dont have my test notes in front of me for proof, but i think the ffl351a version pulled more current than the 519a version.
The tailcap spring in the E07x Canon seems underwhelming compared to the beefy beryllium spring in the E07x Pro. I wonder if doubling up the spring or adding a bypass would make a difference here?
Honestly i doubt it. The high cri 519a doesn’t get as bright as a cooler white or lower cri led, amd the spring is a good quality BeCu spring. The solution for more output in the E07x is different LEDs (xp-l HI, xp-l2, Sst20).
Interesting. I don’t have mine yet but it’s supposed to arrive next week so I’ll look into it then.
One thing I should mention: Thermal regulation operate to keep the temperature below the limit if possible, that means it will somewhat start throttling down before the limit is hit. It is possible it is doing it too aggressively though, which is a reasonably easy fix if so.
