...tead of 36V in UPSC (Battery.voltage). I think that this should be corrected so the customer can see the string voltage and not the single Cell voltage (Megatec 0.06). - About battery low and high guesstimation the formula uses these values: batt.volt.low = 104 * batt.volt.nom / 120 (for a 12V VRLA --> 10.4V batt.volt.low) batt.volt.high = 130 * batt.volt.nom / 120 (for a 12V VRLA --> 13V batt.volt.high). In my opinion these values are not correct (a 12V lead acid battery can be charged up to 13.8V while discharged to 9.6V) Instead I would suggest: batt.volt.low = 100 * batt.volt.nom...

Adding drivers to NUT?
Dear Daniele, nice to meet you, I'm a collegue of Gabriele. The problem with "blazer_usb" driver ("blazer_ser" works correctly) is related to the following commands: - "F" and "I": when the KRAULER subdriver check these UPS answers it uses wrong constants to check the lenght of the received packets, so these commands are considered as "not

According to my notes, it has been just over 4 years since I installed them. Looking at on-line sales, these seem to use batteries in a pre-packaged plastic shell. I don't recall if
