I could very well be wrong, but I think the voltage gauge is displaying the voltage being supplied to the battery. So if it shows a low value, the battery is getting minimal charging front the alternator. When it shows a higher value, the alternator is charging more. That seems to fit what you’re seeing for a battery that’s maintained carefully on a battery tender.

Again, I could be mistaken.
You would be correct. It's pretty normal to see 12.4 - 14.2 just depending on what the car is doing. That is about what my car does on the LiON battery, as it did on the factory battery.

The li-ion battery might make the car report lower voltage values and that is a good thing, meaning the battery is charging rapidly, when you see higher voltage values will mean the battery is discharged or failing.

Will the stock charging system work for the lithium batteries?

Mine has gone 16 days sitting and is still @ 13.25V (92%). That’s on a premium car with security enabled.

There are too many threads/comments to go through so I apologize if this has been mentioned already.

How does it work with trickle chargers? Would it work normally as if it was a lead acid battery?

From Antigravity's FAQ:

No. We do not recommend using any battery tender or other lead-acid standalone charger with a lithium battery. The reason is that lead-acid chargers will tend to overcharge a lithium battery. Additionally lead-acid chargers often have special modes like Desulfation Modes that can spike the voltage to the battery. This can damage a lithium battery.

Yes, it does work the same...you just have to have a charger specifically for a lithium battery.

Apologize if I missed this. But I’m going to be ordering the antigravity ATX-20 soon. Am I suppose to buy a charger to get it to a full charge before install?
