Venom Chargers are hit and miss in quality sometimes you get a good one, sometimes you don't. I would get one of the duratrax onyx chargers if you want a good cheap charger.
As for cheap batteries, Turnigys and Zippys are good for the price you pay for them but for a few dollars more you can get a Gens Ace pack from hobbypartz.com that has even more power than many big name packs like max amps (max hype) or venom.
