whats a good lipo for Mamba Max w/ 6900 on Rustler
 

I have a Mamba max with a 6900 motor. I was wanting to know what would be the best 2 cell 7.4v battery for lasting long and have good run time. and is StickMan Lipo good or trust worthy

this is the overall concensus I got from another post...but regarding a 5700 in a Slash..http://www3.towerhobbies.com/cgi-bin...?&I=LXWSS2&P=0

SMC 5200 mAh 24C Lipo
 

+1 on the 5200 SMC pack, i got one about 2 months ago and was totally impressed so I just got 2 more.

Check out thebarnfloor dot com for a good deal on them.

Awesome! They have a great deal on these....70 bucks!!!!

Stickman Lipo's
 

Stickman here. Yes the lipo's are legit. They are my newest product and come in 5000mAh 25C and 3700mAh 20C. They are imported from the same manufacturer as many others including trinity. They have tons of battery building experience trust me.
I had 4 made and tested them extensively before releasing them to the public. I have been running both packs in my Slash at local races around GA and have not been outrun by anything else. I post equal lap times as the best here and its just my inconsistant driving that keeps me from winning. I can keep up with 35C Losi packs and Reedy packs.
This past weekend at the first GA Champ series race the Slash Class was very tight racing. Who came out on Top. Kent Darley, running a 5000mAh Stickman Pack. I came in 4th with mine as well. Thats 2 of the top 4 running the Stickman Lipo. The race was 10 minutes and the power never faded a bit. Lap times were as good or better as the race went on.
If you have any questions or concerns about the batteries or are interested in a fine balance charger that goes perfect with them let me know. Visit the website for specs and send me an e-mail on the contact page if you have any questions. www.stickmanrc.com :nod::nod:

any 2S Lipo would work, be sure to choose the appropriate gearing. Note that the rustler has a super fast transmission gearing, so a motor of 5700 on a RC10B4 or T4 will equal the rustler's 4600. Putting a 6900 in a rustler is just plain retarded. You will have to change the throttle curve substantially. The brands don't really matter, just as long as you get the appropriate maH for you and C Rating. Note you will need to add weight due to the light battery and extreme horse power. Prepare to break parts!!! It is very easy to be going fast then give a little more power then back-flip with that much power.
