psp extended life battery kit/ protective cover

the psp extended battery looks pretty cool but one thing bothers me, does the enlarged battery cover prevent you from using protective case covers?

my cover is the joytron clear cover, it sticks pretty close to the psp, its also probably the best psp protective case out there but i dont think it will fit with the enlarged battery cover.

so does anyone know if covers like mine will still fit?

it definitely won't fit the joytron case unless your case specifies that it works with the extended battery cover. the joytron case is a hard case, so there's not way. if u had a silicon case, then it's possible, but it'll still stretch it a bit, but it'll still work
