Good-day, everyone!
Does anyone know of a battery holder for the Arduino Uno or ESP32 that supports circuitry for querying the remaining power level?
I've searched this forum and other maker sites but I've failed to turn up anything.
Thanx in advance for your feedback.
I've not taken a great interest in battery chemistry but I think a lot depends on the type of battery you are using and its discharge curve.
What type of battery were you intending to use?
I am using rechargeable lithium-ion.
My assumption is that the battery holder is agnostic to the battery type, but I could be wrong, as long as the holder is capable of determining remaing battery charge.
They sell things called "Power Pack" or similar that do what you want.
