I think it is pretty fair. It’s not super accurate, but close enough for the average person.
Cells were 30Q in both lights.
Assumed new.
Tested with only 4 cells each to keep things even.
The 35E cells tend to have more voltage sag under load, but run longer on the GT once out of regulation. You can see the runtime charts here in post 3 of the GT thread. They used Panasonic 3500 protected cells, but it is pretty close to 35E chemistry. [PART 2] Official BLF GT Group Buy thread. Closed, but Public sales open! - #3 by Team-Giggles
35E or similar high capacity cells are not recommended on the MF02/04 due to it using a boost driver. They recommend high drain cells like 30Q.
I’m sure we will get more accurate turbo runtimes on the MF04 in the near future.
Getting both lights together with the same cells, conditions and test equipment would be ideal, but it hasn’t happened yet.
I think the biggest thing to take away from these run time tests is the big difference between 2.5A and 2A. For anyone that has a GT they can see firsthand the difference in brightness and it is very little. You almost can’t see the difference, yet it extends the run time from 30m to 50m. That’s huge!
