PAS display battery accuracy

[RadBod]

My Rover/Rhino 6+ PAS display featuring the battery indicator has a very questionable level of accuracy. I jumped on my bike today displaying 4 bars but after about 1 mile I was down to 1 bar! This was half uphill, half downhill using a mixture of all 6 PAS settings (including 0). I suspect the actual battery was sitting at 1 bar when I started which would mean the PAS indicator is WAY off the mark.
