Battery help.

If it's a first robot stick with nihm packs and a normal charger. It most cases it works out really cheap and they will still give easy discharge rates. You need to know what you're doing with lipo.

edit: I'm not sure how genned up you are but get read up on charge / discharge rates in mAh, generally the higher quality the battery the quicker it will discharge. 12-24v is usually enough for most people, if you need more you could possibly look to a physically bigger motor within the voltage range.

The main reason for people moving to lipo technology is to cope with the rising popularity of brushless motors that require a crazy amount of performance from the battery. As far as I've seen, if you're staying with a conventional brushed motor setup then nihm packs will be fine for you.
