Where is it from? First consider the speed of the vibration. If it is wheel or axle related it will be a slow vibration. If it is driveline it will be three to four times faster. In the realm of scary. To understand what slow is take the wheel weights off of one of your four wheels and go for

Yes, UL listing to sell something is not necessary. Back to inverters. Be careful buying non UL Asian inverters. A lot of them do not have a neutral to ground tie. You will find instead that the ground prong or green wire is actually tied to the center tap of the output and that NEUTRAL is 60

I would suspect that sunlight on the display raises the current draw of the display. This current draw is on the 5 volt regulator of the entire meter. Being an inexpensive meter the 5 volt regulator is also the reference voltage for the meter. Current goes up, reference voltage goes down.

Ted, I am not so sure it would be a commutator bar. If it were you should have worn brushes down by now. My guess would be more like a winding broke loose and as rpms increase it moves out to hit the field shoes. If it were me I would disassemble the motor and pull out the armature. You will see

To be simple it is not all about just the fact that all cells get the same amount of current, thus a BMS is not needed. If this were true then the 6 cells in a FLA would not go into horible unbalance as they do. So to be simple, as I am, it also includes internal resistance, then by math,
