Arrowmax Scales?
 

Does anyone have experience with these? Wondering if they are only powered via 12v? AA-ish batteries? Or something else? Can't seem to find the answer anywhere and Arrowmax on Facebook hasn't responded in about a week.

The power lead pictured leads me to believe they can be powered by a 12V power supply or a 2S Lipo like the skyrc corner scales, may just need adapters if you have 5mm bullets on your batteries. Not sure if there’s also a tray for AA batteries on the Arrowmax scales.
