I’ve got two Sofirn lights and the third one coming. They all have simple green/red battery level indicators on switch-on, which I like for their simplicity and actionable information. Another advantage of the switch-on indicator is that it is usually based on rested voltage which is more indicative of the battery SoC than sag voltage, I think.
The problem is that I’m getting confused already as to what they indicate. Two of the lights have 3 levels (green, red, red blinking) the other one four (green, green blinking, red, red blinking). The boundaries between levels seem arbitrary: e.g. the threshold between the green and the next lower level could mean different things from 75% to 60% to 30% to the descriptive good/bad.
I don’t even know how accurate the described levels are - has anybody ever tested what those colours actually correspond in terms of voltage?
Wouldn’t be it great if Sofirn standardised on calibration of this simple but useful type of indicator? My preference would be 4 levels in ~25% steps, just like in SF16UV - simple, intuitive, and easy to remember.
