From the, "It's the little things that count," department, Sanyo is set to launch a rechargeable battery pack in Japan, and hopefully here in the states. The pack, licensed by Nintendo, will replace the two AA batteries and the cover.
We currently use Sanyo's eneloop batteries in just about everything we can...you know, earning us some environmental Karma points. As convenient as that is, it'd be great just to have one pack to snap in and out.
The pack also features that certain "wow" factor. Just place controller and battery pack in the charging dock and it charges via magnetic induction (like my toothbrush). Shazaam!
No word on price yet or a US release date yet, but we'll update you if we here anything.
