Interesting...
Over the past week I have casually reviewed various Li-Ion data sources, and I've seen surprising variations.
Up until recently, I had assumed that it was typical to charge a Li-Ion cells at 0.5C.
It appears that depending upon individual manufacturers chemistry variations, that you could expect to be informed
that they will recommend anything from 0.5 to 2.5C !!
But the average is 0.8C.
I'm not convinced that I need to be in a rush to change my own supplied NanoVNA cell.
The specsheet on the VNA indicates anything from a 300-500ma cell, which when supplied may have been sitting
around for a year or two in partly of even fully discharged state before being fitted into a NanoVNA.
Given that expectation, and the current draw of the vna anyway, I'm seeing 2.5 hours of use from a single charge
and no apparent overheating or explosions (!).
Of course, in due course I may see a variation in performance and change my mind ?
Not sure if I'm one of the luck ones, but I've had good fortune with my VNA (Black non Gecko)..
I bought it, it worked, seems as accurate as can be, was dead easy to re-box and just sits there ready for use
when I need it. Perfect !
