Need the best lipo....what brand?
 

I'm running a rustler and going for speed. I have hit 84.9mph by gps with a medusa 2200kv and a dymond 6S 4000mah and a modded MM.

I used my eagle tree and during my runs I pull 74-76 amps for about 3-4 seconds. My lipo drops volts to around 3.4vish per cell.

Looking to hit around 88-89mph. Was hoping a lighter(smaller) lipo with less voltage drop to get there. What do you guys suggest? Thanks

The 25c flightpower lipos are about the best out there for voltage drop under load. Not sure if you will find a lighter lipo, but the 3700 fp lipo should fit your current demands...

this site will tell you the weight and other specs of most lipos available Link to the 6s page

I agree with the post

yep i run the FP 25c as well.

I use the Thunder Power V2 extreme now (same quality than Flight Power), and it's a great li-po, and Pat, at rclipo.com is a great guys.

some new packs. looks pretty good decent price as well

for a $1 more, you can get these packs....they come wired with deans and hard casing as well. how come you chose the thunder's...are they better? and these packs are 30c cont. also

I would say any pack with enerland cells is supreme. I will say that my flightpowers are the finest lipos I have owned. The assembly, performance, and packaging is second to none. I also like the fact they come without a connector because I would just assume install my own.

I decided to build two packs. I ordered some elite 3300mah 30c cells today and will order some loose enerland cells if I can find them.
