U mean the Charge current is 27-28V.....for 24v Batteries...
Yes, it would be nice to have the equipment rated for 28-30V like the
Mikrotik's....
But that is something we need to ask Ubiquiti to do....
Pushing the existing equipment to 27v, has been documented to be
'in-consistent' .

Call me Stupid... but what is the point of this discussion ?
Operating the Radios @ 27V is exceeding the Mfg. Specs. .....
Will they work ? maybe...
Will they fail ? maybe....
If you burn them up..... you are on your own.. ? or at least at
UBNT's discretion, since you are voiding the warranty, by
operating our
of Specs.
Will it shorten the life of the Radio ? maybe...
Will is just work fine ? maybe.....
This reminds me of the discussions on the CPU Over-Clockers
Forum......
If you want to play, sure nothing wrong with that.. but you are on
your own ..
If you expect it to preform well for a long time, then it is
best to
stay within the Mfg. Specs ...
I have often said this to folks.... In our industry, when you exceed
Specs.... things don't just 'break'.... but they do start doing 'funky
stuff'....
Of Course YMMV
