Tested this in my Tamiya midnight pumpkin, which has a different 27t motor vs the stock one & it's great nice & punchy all the time until low voltage cutoff was reached on the Hobbywing 1060 esc.
It was picking up the front wheels the entire time, being a 27t motor it ofc sips power still so it lasted almost 23 minutes for me here, granted i didn't go full speed constantly with this but it's a blast running this old truck about.
Mounted the pack in the chassis where the electronics sit on the left side & used a battery strap i had laying around to secure it.
