if you are just doing nimh or nicd get the reedy quasar or something equal. Amazing charger. Completely programmable. Tells you how many amps is chages and discharges etc.. I'd go with the cheap nimh 6800 or 50000 packs on ebay. Everyone seems to be getting a lot of run time. I'm rocking 2 reedy wolfpacks, which are double the price.</p>
