Well I was kind-of surprised to see this battery is only $175.00. Not bad, considering what it will replace in NiH batteries.
Seems like it would be good for my stock powered E-MAXX too.

I think if you look around you can by that battery for $158.69 at www.cheapbatterypacks.com and Max Amps has an 8000 mah 7.4 volt pack for only $109 that is alot cheaper per mah than quality nickel cell packs.
