IMO anything over 35-40C is probably a big waste of time & money for a stock truck....probably for something modded too. It seems like the local pros that I have talked to have said that they are moving away from the super C ratings to larger capacity batteries. One guy is running a 30C 9000mah (yes, you read that right) battery in his Slash with good results. He says the lipo weighs as much as the slash and costs more! The weight actually makes the cars/trucks more stable. Anyway, the big battery debate is probably a little off topic. I use to race stock successfully with 25C batteries and I'm not sure that moving up to 35-40C packs made a difference. I did just buy a 6500mah 60C MaxAmps pack and by next week I will let you know for sure if it makes a difference in my SPEC class Blitz. It might in something highly modified but I'm even unsure about that. I just wanted to have something special for my 4x4 Slash when it gets here.

For stock slash, a 20C 5000mah batt is more than good enough. I run the same batts on my stock slash in our spec class, and it works great. No need to get anything more than that. I even run the same 20C 5000mah 2S batts in series in my 1/8 brushless setup.

20c should be good enough although anything higher cant hurt at all ...

is the SMC 2S 6000,8000 and 9000 @ 28C too good to be true or no? I just saw them on ampdraw.com and think I drooled. Didnt know they made them that high of Mah......If I hear they are worth it i'm going to go broke buying some!

If price isn't an option, go for it. If you want to start with a value-option, going the Turnigy/Zippy route would still work fine.

The weight of the 9000 is interesting - but you could add weight to the chassis with lead (cheaper than LiPO per gram). 9000 30C would be 270A while a 5000 would need 54C to get that amp output. 20C is 100A for a 5000 and at 7.4v that is 740 Watt potential - way more than a stock 12T motor would need.

I just don't see the point in buying a $200+ lipo for a $200 car unless you are typically running 3rd in the A-main and want to try to use technology to get the win.

I like high mah batteries just to be able to run longer, get in multiple runs, don't have to worry about draining the battery too low, and geared correctly can result in long, long runtimes.

Well I am just one individual but..
I have had great results with my SMC's

I also run TP,Max Amps, and Intellect.
No Complaints on any of them

I have 2 of the flightmax 1600mah lipos for my 18T's and I like them in those but 1600 is too small for me for the Slash. I like long run times when I am out bashing! and as far as $200+ for a lipo pack... ampdraw.com has the SMC 6000,8000 and 9000 and plenty of other high MaH packs for way cheaper than I have found elsewhere

Just get some of the Turnigy 5200 30C packs. Lots of guys say they seem punchier then other high dollar packs at the same C rating and cant be beat with a baseball bat for the price. You can get 2 of them shipped quick an still be less than a "big" name brand. I quoted big because now Turnigy and Zippy are the biggest out there probably. Now to get them to make a pack other than 6S that fits my Ve8.

20c is enought but if you can find a deal or don't mind the coin a 30-35c will more than do the trick...I use a 5200mah 35c and it's got loads of power I also ran an spc 5000 28c(but it's dead now).I am going to be trying out the turnigy batteries myself soon have heard good things about them and the price is right $23bux plus shipping and it's still cheaper than most lipo's

i really like my flightmax 20c 1600mah lipos for my assoc. 18t's but I dont think I will get as much run time from them in my Slash so that is why I am getting something 5000 or higher. and on ampdraw.com the price on their SMC packs is about $30+ cheaper than my LHS and other shops around. $76 for a SMC 6000Mah I dont think is bad! i checked my LHS and they were $112
