Let me know how your conversion turns out.
Mine charges but takes forever to cycle... Like three minutes. And I haven't gotten it to fully charge yet. I left it on the charger for like 6 hours and the light never went off.
I was pleasantly surprised that everything worked like new, especially considering it was a goodwill find.
My biggest issue is that the pack is too tight and I ruined an entire pack of fp100c today by tearing the dark slide, and subsequently messing up the frames from torn tabs.
