Yesterday I implemented a new command "vbat_offset" to allow calibrate battery
voltage measurement for NanoVNA. Also I tested battery for two full cycles
with voltage measurement (with external precise voltmeter).
IP5303 starts to blink with LED at about 3052 - 3072 mV. The voltage drop
speed is very fast at low voltage, so it's hard to catch exact value. Also it
power off device when voltage drops below 3000 mV.
I have all instruments and tools to exactly measure the voltage behavior of my NanoVNA. I'll try and find the time one of these days.
