I completely understand that, and that is exactly what I am trying to figure out in the event that I am outside and I only have my remote keyfob. I usually only carry my remote keyfob outside, and I do not want to be caught unexpectedly when Antigravity BMS shuts itself down and I cannot even get into my car since I only have the remote keyfob.
Sorry that my explanation maybe a bit confusing, and that I may have an unnecessary concern. This is my understanding:
- AGM rating is roughly 100 ah @ 20h = 5 amp for 20h (full discharge)* will try to keep the car electronics alive as long as it can
- Antigravity rating could be 60ah = 60 amp for 1h = 6 amp for 10h = 3 amp for 20h (full discharge)* BMS will shut off even earlier to allow remote jump start
That sounds to me that considering that the battery is low on charge, with Antigravity battery, there is a higher chance that Antigravity will shut itself down faster than the AGM. This means that I cannot even get inside my car if I only have my remote keyfob. With the AGM, although I have a higher chance of not being able to start the car, but I have a higher chance of still being able to unlock the car via my remote keyfob, and access my emergency jump starter/jumper cables inside my car.
My basic concern is that with the Antigravity, it becomes more necessary for me to carry the mechanical key or the remote jump start around at all times (because of BMS shutdown likelyhood), while previously I mostly just would carry my remote key. I wish there is a way to jump start from the app since there's already a communication channel to the battery.
Is there a good place to hide the remote jump start somewhere outside the car so that it does not fall off at high speed?

If you've been living with a strong parasitic drain, and/or a failing battery, then its understandable that you're very concerned about the battery dying, so perhaps you should just get the biggest Ah battery you can find, and that is likely to be 110Ah or more. It doesn't make a lot of sense to buy an expensive Lithium battery for a car that you don't touch for months at a time.
To keep a remote secure under the bonnet I'd use the keyring to hold it onto a cable somewhere in a dry area, its only there for a very rare emergency, not for daily use, so it just has to be reachable, not necessarily easy to reach

When you guys change out your batteries (which I'm going to have to do soon), do you use a 9v memory keeper? I've always heard that it's bad, bad, bad to let these cars totally die, so I was planning on using the one I have...

Speaking about getting into the car when the battery is dead:
The door window needs to drop a few millimeters to allow the glass to clear the drip rail. If the glass does not move down the door cannot be opened (in a coupe at least).
How would you get around this little snag?

Not saying this is the way it should be, but when I swapped my battery, the window didn't reset but I could still open and close the door with the glass all the way up. It only barely snags and the window flexing a tiny bit lets it clear, same when closing the door. I didn't even notice it was doing that for a while.
