Hey. New user here. Used BlackVue cameras for several years, and battery back-up for the last two. I have a couple of tech questions I'm hoping the forum might be able to help with.
TL DR
I've upgraded to a Cellink Neo 9000mAh, which seems to have rendered my original Cellink B 6000mAh defunct. Can I use the Cellink B as an Expansion battery?
Full story. I have a BlackVue DR900S-2CH, dual camera system, 4K for the front, 1080p for the back. The Cellink B is a 6000mAh battery that has been excellent for keeping the system running in Parking mode (time lapse feature) for anything between 12-16 hours. However, there's no way to tell how much the battery is holding, other than the "full" light that comes on after the car has been running for a while.
So. I upgraded to the Cellink Neo 9. A 9000mAh capacity with bluetooth connectivity, where their app will tell you how much is left in the battery as a percentage, and works out roughly how many hours the cameras will run for. It also tells you how much it should take to charge whilst the engine is running.
The question here is that the Neo 9 has a yellow IN/OUT connector, to allow an Extension battery to be connected and used to add more capacity. The originally installed Cellink B also has an Extender IN/OUT connector for the B model add-on. According to an online chat I had somewhere (can't remember) they told me the IN/OUT of both models is 14.8v 5A.
So, my very old physics knowledge tells me that I should be able to use an extension cable and connect the IN/OUT of the Neo 9 to the IN/OUT of the Model B standard (NOT the Extension battery, and also NOT the main IN as that obviously doesn't output power).
If that's all gobbledygook, then here's a mock-up image of what I mean.

Without proper documentation, can anyone tell me if this wouldn't work? And if not, why not?
Does anyone have official specifications for the IN/OUT connectors of both these batteries?
Also, the Cellink B has an OFF/5A/7A switch. Would this have to be set to anything other than OFF to be used as an extension?
With Extension batteries, is the battery smart in that it charges itself first and then once fully charged pushes power to the extension, or do they both charge at the same time?
And with that, does it drain the extension first and then drain the main battery, or the main then the extension, or both batteries at the same time?!
Seems crazy to a Cellink B owner that upgrading to the Neo just to get the bluetooth sensor information potentially renders your first battery redundant. No?
