thats a good charger that will suit all your needs. As far as batteries are concerned stick with something around the 1800 mah size. Unmatched nimh packs will not have a long life span. The cells won't peak consistantly togather and this will overcharge them and cause damage to them. If you overcharge a nicd pack it won't damage it. I would personaly pick up 1500s. You should not have any memory problems with these, higher end nicd packs need to be put on a discharger every other run. The 1500s are ready to be charged after sitting 2 or 3 hours and will only set you back about 12 a pack. These packs are very durable and hold up well to abuse so you can fully learn about battery care, plus they are a small investment so you can purchase 5 $10 mistakes instead of one $50 mistake. Plus when you push an r/c car for strenous amounts of time it is not good for the electronics. Taking that 5 minute break to replace the battery and stuff once every 15 minutes will be good for it. I am unfamiliar with the electronics that come with the truck but odds are it comes with a mechanical speed control or a very low end speed control. If you do some research you can find high end speed controls that are slightly out dated, still much better then low end escs for under $50 on ebay. These high end speed controls will cause much less resistance and should increase your run time by about 25%. Some of these escs include a novak cyclone or an lrp v7.1.
