    I hope someone is in the same boat as me and came up with a solution. I have a new R6 and a couple of 6Ds. I shoot a lot of unattended time-lapse, sometimes 8-10 hours at a time. I'm looking for a portable, field-use external battery that will power the camera without having to change batteries. I have an extended grip for the 6D, but I need something, preferably an external battery pack that I can connect to the CANON dummy battery I already have. The trick is the voltage has to be somewhere between 7.2 and 8.4 volts.
    Has anybody come across something that may work?
    Thanks,
    @BruceBergerAstro

    Welcome to the forum, Bruce. My only suggestion is can you hook 4 batteries up in tandem, hooking them up to the camera would be a issue, try GDN, he is into Astrophotography.

    @GDN, Hello Gary, I'm, new to the forum and have been shooting Canon for over 20 years. @Craig Sherriff thinks you might have a suggestion for an external battery pack for an R6. My night time lapse shots are lasting 8 hours or sometimes more, especially with Winter getting close here in the US. I don't want to buy a grip, at least not at more than US$ 300. Any suggestions?

    Hello Bruce and welcome to the forum.

    I am in a similar boat to you in the fact that need external batteries. But I use 12-volt batteries which are easier to pick up. This battery is used to power my mount, but for my camera, I take extra camera batteries and swap them out as they drain. When I brought my camera, Canon NZ were giving away a free battery, and I ended up being given an extra one on top of that. I have three batteries, and I am yet to chew through all three in one night. In fact, I am yet to drain two of them. And I have a RP, and the batteries are pretty small.

    Of course, this does not help you out with your problem.

    So, I put my thinking cap on which is dangerous at the best of times, and I went looking on the internet.

    What I was thinking is can you connect your dummy battery to one of these?

    7.2V Ni-MH 3300mAh R/C Battery | Jaycar Electronics New Zealand

    Or an equivalent sort of battery from a supplier in your neck of the woods. You may have to change the connectors on it. If one battery is not enough, I would wire a second battery in parallel. What sort of amperage drain does the camera draw per hour? Or how long does the camera work with a fully charged internal battery? You then should be able to work out if you need one or two batteries.

    I would also put a multimeter across the battery once it is fully charged before connecting it to my camera to see what it is actually outputting.

    Let us know what you think.

    Thanks Gary! I often leave my camera out all night, unattended, so changing batteries is not always going to work. I did come up with a solution that I think will work, and I'd like to share it.
    I use a TalentCell 12V + USB Li-Ion Battery Pack to power my camera tracker, and sometimes dew heater for the lenses. I purchased another of these - https://www.amazon.com/dp/B00ME3ZH7C?psc=1 and also a 12V to 7.5V 3A Buck Converter - https://www.amazon.com/dp/B00C66B3PM?psc=1, both on Amazon. The Battery Pack is rated at 12,000 mAh, so roughly 5-6X the capacity of a single LP-E6NH. I already have the Canon Dummy Battery Coupler - https://www.usa.canon.com/shop/p/dc-coupler-dr-e6c?color=Black&type=New so I'll attach all with some proper connectors and see what happens.
    Happy to let the group know how this all works out.
