Volto -- anyone try one of these out?

I got a cheapo RC battery pack and charger of ebay for something like AU$20 inc. postage, and use it to power my grab-and-go board.

Wow, what a cool sounding project ! I have already bought two 8 AA NiMH batteries holders from adafruit
but Lipo's seems better. So can we pack lipo's batteries + charge unit in a box, say 1590B ?
And maybe the tri-color led charge indicator ?
What you think ?

The charger circuit for an SLA battery is on a 1x1 inch board, but there's a TIP42 transistor that needs a heat sink. I have it in a small Radio Shack plastic box that is taped to the side of the battery.

I don't think the TI Li-Ion/LiPo chargers use a transistor like that, and the batteries are definitely smaller. An actual 1590 might be overkill, since it wouldn't be stepped on. But with deliberate battery choice, it would fit easily in a B sized box of some sort.
