One Li-ion/poly cell is 3.6V. So it's a single cell, maybe multiples in parallel, but who knows. There are 20A and greater LiPo battery packs for electric airplane applications, so it might not be necessary if they found a high-discharge cell that did the job. I hope they at least do this, if not a 2700+mAh batt when the make bigger ones available. And I hope they allow 3rd party batts. PEACE.mr2mike said:well perhaps some battery packs are higher than 2550 mAh, but it can be due to the arrangement of cells in the pack itself.
The PSP's pack looks about the size of 3 AA cells, and since it's 3.6V, we know they couldn't have setup some cells in parallel to increase the amp rate, because you need a serial setup for the voltages to add up. 1.2 + 1.2 + 1.2 = 3.6V, using 3 1800 mAh cells.
But then I still dont understand why Sony used 1800 mAh cells when even their digicams ship with 2100+ NiMH
If this is really industry-leading capacity, I would expect it to either be a $80 spare battery, or a late 2005 item. I'm really interested in what Sony does with the battery tech for the PSP, b/c that's where it's gonna make the gains in play time. It'll hopefully let the devs take full advantage of the system some day. I really want to know though, how the hell do you charge the spare outside the PSP?

2400mAh is already available. Why isn't in in the PSP then? 40% bump in price and form factor? Doh.Pimpwerx said:1800mAh - 2550mAh >> 6-9%. Try a 40% bump in capacity.
Yeah! Don´t we just love Sony for bringing "LOADING" into the handheld market? :lolStoOgE said:hey, you'll only have to switch the batteries TWICE while loading ridge racers.
