[Nut-upsuser] Re: NUT mustek UPS driver (fwd)

[Alexander Kostadinov]

Hallo again. Below I give you the information you told me to give. I just 
want ot mantion that 2,31V should be the voltage of the battery cells. One 
friend told me that it should be 1,2V so every battery should be 12V and 
the the 3 batteries in the unit should be 36V. (The UPS has 3 batteries of 
12V - explained in the documentation).
The mustek driver works fine but gives wrong battery capacity percents 
because it also expects battery but not cell voltage.
