a123 or lipo.... and other ?s

Personally, I would go with Lipo. They are better in almost every way instead of cost and their hazerdous nature.

However, with a proper LVC, the only hazard is physical damage. In a rusty, if you have them properly secured, it will be nearly impossible to damage them unless something actually enters through the body and physically hits them. The other possibility is breaking your chassis, in which you will probably have other, more expensive problems if you happen to accomplish that.

I have just gotten the 2S2P 8000mah packs for my G2R and they are insane. I'm very happy with them so far (I've only ran them for about 5 minutes). I'm hitting the track tomorrow to put them to the test.
