I put the wrong side of my battery inside my eos 6d camera

I've tried new batteries, leaving the batteries out for an extended period and trying again, nothing works. It's just stuck on this symbol as soon as I put in the batteries. Does anyone have any ideas how to fix it?

Hi everyone! I’d appreciate some advice from experienced wedding videographers.

My wife and I have been graphic designers since 2012, but as design projects are becoming less frequent due to AI, I’m considering transitioning into wedding videography, something I’ve always been passionate about.

I’m planning to start with this setup:

• 2x Canon R6 Mark II (one camera for me and the the other one for my wife).
• Canon RF 24-70mm f/2.8
• Canon RF 35mm f/1.8
• DJI RS 4 gimbal
• DJI Mic 3
• 2x 512GB UHS-II cards + 2x 256GB UHS-II cards
• Nisi ND 2-32 82mm
• Godox V100 flash with softbox and light stand

My current budget is ~8500e. Looking forward to buy all these in the upcoming black friday deals.

I’d also like to use the equipment for commercial work, such as promotional videos and restaurant/product photography, using the Godox flash and softbox.

I haven’t worked professionally in photography or videography yet, but I’m willing to work pro bono at events and with local businesses to gain experience and build a portfolio before taking on paid clients.
For those already in the industry: Does this setup make sense? Would you change anything or recommend different gear? I’d especially appreciate advice on whether my lens choices and lighting setup are suitable for weddings and restaurant photography.

Besides this, I need to also upgrade my laptop in order to be suitable for video editing. I was thinking that this would be a good option. My extra budget for the laptop is 2000e. What do you think about this?

Thank you so much in advance,
