Hi,
I have a psp 1000 and am wanting to do a internal battery mod. i want to have 1 or 2 psp battery's connected in the UMD door (which i no longer use and will be taking out) in addition to the normal battery. however, i am not entirely sure how to connect them, and have found little information online. i have seen a mod where someone tried this, but only using the positive and negative pins of all 3 battery's. he could not charge two of the, only the first one. i have heard of others connecting all 3 pins in parallel of all 3 battery's. this however does not work either. lastly i have heard of people running 3 cells on the one circuit board- however the threads are old and there is no information of if this can charge.
so, my question is has anyone done this mod before or something similar? and have u tried any of the combinations i have stated? have any succeeded? Thank you.
