Accuracy of Queclink GB100 supply voltage measurement

John Williams3 years ago

I have a Queclink GB100 connected to a camper van lithium leisure battery.

The GB100 is set to only report GTINF every 5 minutes which it is doing as expected (i.e.the GPS is off and not reported)

The GTINF report from the QB100 includes the supply voltage.

What bothers me is that the indicated voltage is jumping up and down by about 30mV. Is this to be expected from a Lithium battery with an internal BMS?
