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
