I agree, I would go Lipo too. Or get the Trak Power if you are going to 2s1p...better discharge rate for the buck too :)
If you want nice packs, get some Nimh for now, and save you bucks for lipo....it's worth it in the long run, and really, if you treat your packs well, they are not that unsafe.

yeh but the pack in my flm pede is dented, scraped and has came unglued 4 times now lol i dont bash like a sisy i bash REALLY HARD and idk if lipo will hold up thats why im looking into the li mn

if your hard on your truck you dont want those unprotected packs.
you want hard casing aroun the lipo cells.
there is trakpower( part of flightpower) and there is orion and peak.
the latter 2 or the same brand actually.
i have the orion 2s 3200, they are about 450watts continu.
the trakpower is 700 watt continu.
if you would get the LIMN 3s 3800mah it would be around 684 watts.
so trakpower is less speed but more power(torque).
chose what suits your needs, more speed, more overall power.

well the mamba gives speed no matter what lol, so overall power is what id want, good run times to, with out being worried if my packs are okay

when you have lower rpm you can also gear more towards speed, that if the pack can deliver what the MM wants.
so then the trakpower would shine if you ask me.
or the 5800 2s or 3s LIMN.
