Step 1: Materials Needed
1-Ultrafast universal battery charger. Buy at radioshack or here
1-Battery pack 7.2v-(Type outlined in step 3)
1-Rc car to use
Step 2: Unpack the Charger
Step 3: Choosing the Battery
Depending on what battery you have the "fastness" of this will vary. I recomend a small 1500-2000 mah 7.2v battery pack. Also make shure you have NI-CAD, if you have a 2000 mah NI-CAD it will charge the battery in 15 minutes!!!!!! But if you want to go big, go for a 3000 mah NI-MH. This will charge in around 22 minutes with this charger vs 8hrs with a regular charger.
I have outlined some good battery deals below.
2-pack of 1700mh NI-CAD batteries from here
1-pack of 3300mh NI-MH batteries from here

I will be using a Shark 1500 mah NI-CAD, because i had it laying around.
It is the one on the right
Step 4: Charge Time!!
when the pack is charging you will here the fan running, dont worry it wont explode
