Manufacturer: PowerWalker
Model: VI 3000 SCL

UPS sends a low battery signal that makes NUT issue a shutdown. battery.charge.low and battery.runtime.low were only set as failsafes during testing.

upsc:

battery.charge: 59
battery.charge.low: 5
battery.runtime: 81983
battery.runtime.low: 180
battery.voltage: 24.50
battery.voltage.high: 27.10
battery.voltage.low: 20.10
battery.voltage.nominal: 24.0

ups.type: offline / line interactive      
ups.vendorid: 0665

UPS load value is always working correctly.
Temperature is only output when UPS is on battery, value seems correct.
Vendor detection has to be disabled! It doesnt give out information (fails) and causes the UPS to not answer all the time!
Runtime and chargetime based on Mamufacturer datasheet, Min/Max Voltages measured. (Brand new unit)

UPS commands:
beeper.toggle works, also gives out the correct value.
load.on works
load.off works
shutdown.return works
shutdown.stayoff doesnt work
shutdown.stop works
test.battery.start.deep doesnt work, responds with OK, but no action
test.battery.start.quick sometimes works, always responds OK, test is sub 5 seconds
test.battery.start value doesnt work, responds with OK, but no action
test.battery.stop useless, because only the 5 second test works

Hope I did this right! Sorry if anything is wrong, I'm new to the project and just wanted to report my new UPS here!

Little addition:
Protocol is mustek. nutdrv_qx doesnt connect eventhough it also detects it as mustek like blazer_usb
