ok so i got all my parts for my first blu ray, so i was thinking about modifying a dorcy jr to house 3 lithium photo batteries so i can use the rkcstr micro driver since it needs ~9v to function properly. however i found a 6V Lithium Photo Battery at radioshack and i wanted to know if i could just house that one and a 3v lithium photo battery to come up with the 9v. does anyone know if it can work like that??? :-? or is one of the batteries gonna explode or something???
