Lithium ion batteries can fail with catastrophic consequences.
I know that the switch on the NanoVNA is of appalling quality, but I will
address that by an external switch.
The screen on the first NanoVNA I received was faulty - a problem Hugan
said is common.
A quick look found me this battery
a very reputable manufacturer, around 5 times the stated capacity of those
with the NanoVNA, at a cost of about 50% of the cheapest NanoVNA I have
seen.
This one is just ?0.01 extra, from the same place,
but 3.45 Ah.
Based on someone reporting getting 2 hours from a 450 mA hr battery, that
should last 15 hours, so a good full days work for sure.
