BP-511 battery modification

Hello Chien Cheng,

Am a keen astro photographer.

Here are some of my 20d images

My name is Tony Kwak in Whangarei , New Zealand .

Having lot's of trouble with batteries going flat so would like to have a go at modifying my BP-511 batteries.

PROBLEM? Have to have the battery compartment closed for camera to operate!

Any ideas?

Look forward to your reply.

My apologies for wasting your time.

Have just discovered a little rubber flap for the wire to exit the battery compartment.

No problem. You have some amazing photographs on your web site. I hope to try to astro-photography in the future.

If you ever come across a camera that doesn't have an opening for the wires to exit, you can always get a small round file or a small drill bit and make a little slot for the wires to exit. The following web page has a photo where I made two round slots that way:

Good luck.
