ah, okay so the capacity can be any mah, but the volts must be specific or the ps2 won't get any power to run.
so, what should the voltage be so the ps2 can run for 2hours, lets say?
or a 14.8v ?
The mAh tells you how long your portable will last. If the PS2 + Screen pulls around 2A then 2000mAh batteries will last 1 hour. 4000mAh will last 2 hours, 8000mAh will last 4 hours. See?
The voltage will need to be the proper voltage to run the PS2. If you need 8.5v then you will need to use at least 11.1 Lithiums and the use a power regulator to get the voltage down to around 8.5v - 9v for the PS2.
yep, i see. thanx for the clearance, hail
it's super easy to understand now.
okay, so since i want the battery for the ps2(it'll power only the ps2 as the screen has it's own Li ion polymer pack 3.7 x 2 1800mah, which is 2 hours)
an Li ion 11.1v would be the best choice,
and at 4000mAh, will be 2 hours like the screen?
and, since the ps2 voltage is 8.5v better, i tried 9v and my slim burnt out after that.
if i buy an 11.1v li ion 4000 mah and use a step down regulator to bring the volts to 8.5v then it'll work.
also, im going to join to the regulator the ps2 fat connector thing, i have opened one up found the two wires it has, (blue and brown) not sure which one is positive and which is negative?
oh, and im also using the ps2 power supply that the fat has, if the voltage is correct the ps2 will run like normal on battery like on wall power?
and what regulator should i get?
here's a site i got one of my regulators from:http://24x7diy.com/index.php/cPath/28/o ... d4a41dc821
which one of these is best suited for my use?
i checked amazon com just now and they don't have the 11.1v 4400mah, but the 11.1v 2200mah.
