It won't support it without some changes.(haven't looked at
the dev branch though)
For example the megatec driver expects one byte for status registers
(eight ones or zeroes), and the OPTI ups returns two :
"(228.7 228.7 228.7 024   49.4  2.40 30.0   00000000  00011100"
But i agree that it will be better to add support for this UPS in this
driver instead of writing a whole new one.

As there are different models with different number of batteries, but
mostly they are 12V each, do you think it's appropriate to set the
"battery.packs" from this info? (i.e. 36 / 12 = 3 as in my case)

I think that i'll have problems here...
I have just ran this test, and the results look very confusing.
The UPS have an LCD display that has five bars that show the
battery charge (20 percent each).
At this point (100% charge) the battery voltage string returned
from the Q1 query reads 2.40 (i have once noticed it to jump to 2.50
for a very short period)
Then i have disconnected the power of the UPS.
The battery voltage variable started to go down.. it went from 2.40
to 2.00 and shortly after this the UPS began beeping faster. (the LCD
showed 40% charge) also i noticed one of the status registers to be
flpped to On.
The LCD then showed 20% charge... but the variable stayed at 2.00.
And the other thing is that it went down in a very non-linear fashion,
sometimes 2 bars on the LCD dissapeared without the value to change.
I've attached the continous output of the Q1 query during a short
power interruption.

I'll see what i can do in the spare time, but since i own two of them
at home probably i'll try to do something sooner than later :)
