Lipos for Traxxas Slash?
 

Looking for 2 good 2s packs preferably 5000mah or a little higher. Any ideas of something that will perform well and fit? I see the Zippy's are well priced. Thanks

Enerland hard case Lipo or Neu hard case. You do get what you pay for!

I use this in a 3s in my rustler/Maxx and it works great. Cheap, not too wide & I am pretty sure the slash can fit this in the stock chassis length wise.

I'll toss in another recommendation for the hard case Enerlands. I use 2 X 2S 5100's in my E-Maxx and have been super happy with them.
