Use this link for a hard mod guide I am not aware of any PHAT pandora proof batteries re-flash the FW and your set, you might need to re-partion the flash drives, but i would simply try re-flashing it first
If you got your battery with your psp, then that psp battery should be able to do it, however if you bought a replacement, then i do not think the replacement is easily mod-able. I would say, the newer psp battery would be nearly impossible to mod.
