hello
I was just surfing acidmods when i came across a battery mod which extended battery life when i thought "hmmm might aswell do that before i hang up my psp modding shoes for good".
so this is what i was thinking circuit wise
all i need to get is a charger protector circuit for the li ion batteries i've got then i can start
But
i cant find one for the uk
all i can find is this http://www.all-battery.com/protectioncircuitmodulepcbfor37vli-polymerbattery85alimit-pcb1s.aspx
for the us wiyhout shipping to mainland uk
so if any one has something like this please can you tell me if there is such a thing in the uk

ye Sorry i did the diagram on paint with a broken mouse
The pcb Basically stops the psp charging the li-ion batteries when they are full or when there is to many amps trying to charge the batteries
the diagram was ment to go
Take apart ordinary battery (mines hardmodded pandora)
snip off lipo battery
solder the connections to the battery pcb to the correct connections on the battery charging pcb
solder the battery to the batery charging pcb
fire it up see if
1) it plays off ordinary power
2) it charges
3) see if it charges at to low or high amps
its hard to explain and i need another mouse before i do a more detailed diagram
