Built on the foundation of the popular LS C300d, Aputure's LS C300d II Daylight LED Monolight is an enhanced version with 20% more power, refined features, and advanced connectivity. Aputure uses Chip on Board (COB) technology to produce a 5600K color temperature, with power consumption of just 350W, while outputting up to 45,000 lux of light with an efficient reflector at a distance of 3.3'. In addition to power efficiency, this fixture also has a CRI/TLCI rating of 96, indicating accuracy in color rendering. The fixture's ballast/controller employs 0 to 100% Linear, Logarithmic, Exponential, and S-Curve dimming and is separated from the body of the fixture, making it lighter and reducing its size. A quick release plate connects to an included clamp, allowing attachment to a light stand to distribute the weight.

Regarding battery operation,
I understand according to Aputure's documentation that 15A batteries are required to power the 300d II, based on the logic of 350W max power draw requires (12V * 15A) * 2 = 360W.
My question is, if I own many 12A batteries, is there a safe way to use them with this light, by capping the output following this equation:
12V * 12A = 144W max draw
144W is more or less 40% of 350W
So one battery should provide safely and reliably 40% of total output capacity. 2 batteries should provide 80% of total output capacity. Meaning if I underpower the light using these values, I should be ok.
Is that logic sound?
I am surprised that Aputure gave that answer... As power electronics engineer with 40 years of experience, I do not recommend running your LiIon batteries beyond their rating for any length of time. Depending on the quality and age of the cells, and depending on the protection circuits built-in to the battery, you cannot assume it is safe to operate them beyond their rating - this is how battery-pack fires start.
Having said that - yes your logic is sound. Running at 80% max will keep the packs within a safe operating region (12 A). I am also surprised that Aputure did not know that - when you have a single battery installed and set the power level to 80% - that really is 40% (the output of the power supply is cut in half with only 1 V-mount installed). So you only need to worry about keep the setting to 80% or below regardless of whether 1 or 2 batteries are attached.
As a final note - the red-colored V-mount is the master. If you have only a single battery it must be on the red mount. The second battery goes on the black mount. Once the #1 battery on the red mount runs out, the light shuts-off, regardless of how much charge is remaining in battery #2. So plan accordingly to get the longest operating life.

What are the outside measurements for soft case? I need to order a Pelican (or simular) case at the same time. It would be nice to just drop it in.
This Pelican 1630NF https://bhpho.to/2M7UtYF would allow for drop in fit as well as a few accessories.

Can I use with Godox gobo?
Can I use with Godox gobo?
The C300d Mark II is compatible with any Bowens mount light modifier. So if the Godox gobo has a Bowens mount, then yes.

Can i use this light as a flash light for studio photography? And if so, how does it sync to the camera's shutter?
This is an LED light and not a flash. The light is continuous.

Would it be possible to carry a standard light stand in this case?
The carrying bag this light comes with would not be large enough for a stand.

Are you able to charge batteries on the power unit, like with the aputure panel lights?
You will not be able to charge the batteries on the unit. You will need a charger based on your battery choice.
