I asked the following above - does this work?

>> A mid-stream capacitor is holding enough charge for 10 seconds to allow indivdual swapping out -- and also this is meant? to mean that you can swap TWO NEW batteries in without having to shutdown/sleep/power interrupt - thus the 10 seconds.... that dope

EDIT: I was imagining the capacitor holds up the whole thing for ten seconds to swap out both bats...

In theory you could do that, but it has its own costs and complications. And if you're going to add a big enough capacitor to ride out a battery swap, why bother with two batteries instead of just one?

Hotswap of two parallel batteries must replace both with a matched pair. Otherwise the one at higher state of charge starts charging others without current limit.
