Swapping Batteries in Battery Grip

[WaltMarsh]

While recording long events it would be great if there is a shortcut to disable one side of the battery grip, open the compartment door, replace battery, close compartment door, enable battery port, all while recording.

Is this possible?

[Malcolm Debono]

What kind of grip do you have? When I open mine, both batteries come out, so it definitely wouldn't be possible.

Do you mind uploading a macro shot of the battery grip door?

My BG is a clone but i guess every one of them is pretty much the same.
If i start the camera with the batteries inside but with the door open everything is fine.
Then, when you close the door, the switch triggers and you lose power for the amount of time the spring takes to come back into place.
This contact can probably be faked, i don't know, it would be a nice feature for hardcore movie users.

I'm not sure of the name, but this is where I purchased it.

Can you confirm that this works?:
- Start with the lid open and two batteries
- Power up camera
- Hotswap one battery
- Camera doesn't shutdown

If so, I'll have a look at the firmware to see if I can spot something

It wors for me with 50D and BG-E2 clone
I bet every BG works the same

Unfortunately it won't work with newer grips since now the compartment opens from the side, and you need to eject the tray containing both batteries to replace any one of them (see picture below).

My Meike brand grip for my 60d slide out like this...

Both of my grips slide out to the side. I don't think there is even anything besides +/- on the grip anyway.

Does the battery meter even work with most grips? I think on my 400D it seems to and its a tavor grip. On the 600D my meike grip reports full.. hardly ever 2 bars and then "change the battery pack."
