Hello, I, like many others use one of these cheap buzzers to monitor my lipos while I ride. I was wondering if it would be possible to add a switch to this, so that I could keep it connected at all times.
Also, for a loop key like the one below, why is it that the side with the exposed bullet connectors (female connector) is attached to the board? Isn’t this a safety hazard if someone were to put their finger there and connect the circuit? Feeling 20v or more doesn’t seem healthy.
