Another point I mentioned already but feel need to put emphasis on now: If we here collectively develop a new battery solution the result will very likely remain an open source DIY kit for tinkeres and people interested in building their own experimental battery assemblies. Due to the regulations and certificates requires for bringing new battery products to the market we will most likely not be able to afford making it a real retail product..

Using 4 cells with a single pcb on top, forming a unit of battery.
This unit can be stacked to form the size of battery you want, in 4, 8, 12, 16 cells and so.

that sounds good.

From the electronics perspective there is no major change between the two. You can desing different cases that hold the amount of cells each camera needs.
I think tho, that we need to find a common connector and holding for all the batteries. So you can interchange them between different models of cameras.

agree.

What i see a little tricky is the hot swappable battery.

What about having a dual battery mount (two smaller batteries (8cells each) instead of one 16 cell battery)? would it be hot swappable then if you exchange one after another?

I think the following needs a bit of context:

would you like to design the battery exclusively for the axiom beta (box shaped) enclosure or also to fit on the bigger (and more power hungry) ergonomic enclosure version as well?
do you think it make sense to combine it?

There is still airflow if the fan is on, it circulates internally. Magasinating, or loading, whatever thermal capacity there is there.

Well not if you use it as a still camera for just a quick image. (?)

Menga added a comment to T736: Battery System.

One question though is if voltage measurement alone is enough to evaluate battery capacity/health.
I know laptop batteries for example monitor all currents going in and out over the entire battery lifetime and account for any aging phenomenons of the cells.

Laptop batteries don't actually do that, they have something that is almost planned obsolecence. For example, Dell uses a microcontroller that counts cycles anr/or usage hours, but not for each charger, they count the entire life of the cells as a whole (all of them in the pack). When a certain prefix limit is reach, the micro tells the computer, and the computer refuses to charger the battery.
So is a "safe life" protection. The battery may be fine, but because they want to avoid a lawsuit if something happens they just block the battery after a a few cycles/hours.

Well, you can make a led status without a PIC or any microcontroller. we could desing a status around a vumeter IC, like the LM3915., with the press of a button it will tell you the state of charge.
The advantage of an analog state will be 0 current drain. Because you only read the battery when you press the button.

@Menga i like your design approach. does the hight and width (-the space for the hdmi/sdi connectors) match exactly to the backside of the beta enclosure? what about separating the cells in two groups and have one or two screws in the middle instead of having them on the sides. in that case we could also allow the package to be mounted under the camera and still be abel to mount it on a tripod. does 21700 cells also fit inside?
