Rechargeable Battery?

Is there a rechargeable battery for the wii more. not like Duracell type batteries. like for the xbox 360, you can buy a rechargeable battery pack for the controller. Does the Wii have one like this? i waste allot of money on the batteries because i have 4 controllers n my friends play allot, so im just wonding

Do you know if they will sell just the batteries because i looked on there and the batteries only come with the charger, and it would be extremely inconvenient to buy two chargers

My guess is the batteries are the majority of the cost of the charge station since the cradle is just a molded piece of plastic that connects to the USB port. So you might as well buy the set and ebay the cradle if you don't every want to be able to charge all 4 at the same time.
