[Gauging Interest] Safe Shutdown (BangGood edition)

@Camble
Perhaps something between 3.6V and 4.0V... to have a good collaboration with the Pololu voltage Regulator (https://www.pololu.com/product/2123.

for me personally, it's important, because I'm using NiMH-batteries.

So I would like to adjust the shutdown-voltage.

Adjustment possible through changing resistors (with resistors or potentiometer) -> GREAT!

Are you sure the banggood power supply supports NIMH ?
It's made for lithium, be careful.

@SidSilver:

I will neither use the banggood nor the adafruit powerboost charger

. As mentionend I will use the Pololu S7V8F5 and willingly this safe shutdown board.

@johnny-bert I may have resistors I can use to program the comparator with a voltage within your range.

@Camble
That would be great!

@johnny-bert Can you measure the output voltage of your Pololu and let me know? It won't be exactly 5v. Connect up some stuff to it and measure the voltage.

I'm also extremely interested.

Price?

@Camble
I can do the measurement, but not before tomorrow.

Edit: Multimeter said 4.91V.

Two resistors: 115K & 316K would give you a low batt reading at 3.6v
