I used to run 6 cell nimh saddle packs (1500mah) from TCS and got around 30-45 min with fairly standard equipment - 35T, VP dig, hitec 7955 steering servo.

Only been running lipo for 2 packs, but so far I'm seeing around the same runtime (but better performance IMO) on 1300mah 2s lipos from HH.

in my tuber using my 1600mah 2s lipo's, using a CC sidewinder ESC 55t motor, and hitec 7954 on CC BEC, I get about 30 min.

in my scaler using my 4800mah 2s lipo, using a traxxas XL-5 ESC 35t motor, hitec 645 servo, I am guestimating 2.5-3 hours, i've yet to run it dry, but i've takin it out a few times and after driving it for about an hour and a half, it takes 1500mah to charge back up.

in that same scaler a 3300mah NI-MH gave me about 30-40 min run time.

It's about 1" longer then a 6 cell nicd/nimh pack. It's pretty big physically. It's a coyote 4800 off of eBay. Got it for a couple bucks. Perfect for my scaler.

The Bully Kit that you are referring to (MK42) will not have room for a larger battery. I was running a 1050mah 3cell and was getting 2-3 courses out of it when the courses were longer and 5 minute time limits. I just switched to an 850mah 3cell pack this weekend, and I was getting 2 solid courses out of it. I probably could push them further, but I do not want to stall in the middle of a course. For just practicing, I bet that I could get 20 minutes out of the 850mah pack with my setup of electronics. ALSO, total truck weight will play a factor in battery life. The heavier you go....the more energy it will take to move the truck.

Bully Lightweight axles with heavy front tubes and delrin rear tubes. No extra wheel weight.

2 - JP 45T Warrior Motors
1 - Sidewinder ESC w/BEC 6.0v
1 - Punk Dig
1 - Hitec 7950 Servo

I used to fit the 1050mah on the rear axle on a plate, and it was a tight fit. Now the 850mah can fit there easily, but i now put it on my chassis. I have also fit a 1450mah 3 cell pack on the rear axle, but it threw the weight off quite a bit.

Cool this is the info I'm looking for. I knew that 4800 pack would be too big for me but that would be awesome. I don't do comps yet and I wouldn't consider myself a bashed but me and a buddy like to go crawl.for a while and not have to change packs every 10-15min. Its kind of a pain in the A$$ ya know. Just want more time to crawl and less battery changing. I'm gonna be running the mk42 stock electronics for a while. Prolog add a lil weight to the front and that's about it. I JUST WANNA CRAWL!!!!!!! ( not intended for anyone just venting a lil )
