So you got your shiny new Wii Balance Board home and played it until the batteries died. If only you had a rechargeable battery pack. Fortunately, those guys at Mad Catz have only gone and sorted it and released a battery pack that will give you up to 20 hours of continous balancing fun. The battery pack also comes with a USB cable, compatible with both Wii and PC for convenient charging.

The Mad Catz Rechargeable Battery Pack for Wii Fit will be available in the UK at gamestation and in the US from GameShark.
