hi guys, needed some advice from you. Is there a battery pack know as quantum battery 1 compact that can be attach under a camera body, and the dslr is powered by the battery pack. can't seem to find much information on this leh.
anyway, its because my 1d batteries are going to die soon, cannot hold charge. am looking for other alternative instead of keep buying np-e3 battery which is very expensive.
any kind soul pls advice. thanks many many
