I am running a Flightpower 5000mah 25c 6S lipo, the one in Mike's store.

I know this sounds unrealistic and next time I will time it but it has to be 25 to 30 minutes. Even then the MGM Lipo slowdown wasn't engaged. I could tell the top speed was dropping off so I stopped running it. I have only run 1 full pack through it, every other run I stopped long before I had to for whatever reason.

I checked the voltage of the pack when I got home after 45 minutes or so and it was close to 24 volts, so I didn't over discharge it.

I could not believe how long the truck was running, and I was being harsh, constantly stopping and starting. I guess the Neu motors efficiency really helps in this area.
