Exactly. Making it so you can stack two batteries is theoretically possible, but the complexity is sufficiently high and easy to get wrong that I would actually prefer a device that didn't have that feature.
I was suggesting that the P2 could accept one 3Ah battery, or one 6Ah battery. This would only require one set of charging circuitry.
I'd imagine that this would only work if large amounts of control were done inside the battery itself, to ensure that the small battery was not overcharged on the assumption that it held 6Ah.
For example, the battery could be held (semi)-permanently in a removable base section of the case, along with a charge controller.
As a rough suggestion (don't know if this would be at all practical), there could be three lines out of the battery unit:
- earth/ground/0V
- +ve (5V or 3.7V depending on other considerations)
- serial data out
The charge controller would 'know' the capacity of its battery, preventing mistakes and dangerous software features - and would report capacity and approximate charge left periodically to its host.
Another possibility would be have a charging port on the battery (as with Lego NXTs), to allow charging multiple batteries simultaneously, even in the absence of a P2
There's the problemimagining

(a programmable microcontroller with advanced battery management features)
Ofcourse I didn't think they were descrete. They made me sit through a 2 hour presentation on EXACTLY what they do (I wish I had those two hours back)
I think you missed out a '1' thereIf we could get a better processor and graphics, then make it thinner, but I think 15 hours is a good target, and with ARM it's hard to undershoot that. I would love to see at the very least 32 GB internal storage and 1GB RAM, possibly upgradable?
seriously, no one got this joke?the battery wont be removable so we dont go through the whole pandora battery thing again and lose all the money to piracy
maybe too few psp owners around, or it was just too obvious, and nobody dared to say itseriously, no one got this joke?the battery wont be removable so we dont go through the whole pandora battery thing again and lose all the money to piracy
