12V Delay Timer Switch Adjustable
This 12V Delay Timer Switch Adjustable 0-10sec is one kind of popular switch module. You can use it control any devices on or off. This is a DC12V controlled 1 channel timer relay module. It has a NE555 timer chip on the board. You can adjust delay time(0-10s) by rotating the potentiometer. When this relay get powered it will delay several seconds before relay turn on.
Note: Recommended power + series with a diode to protect the circuit.

1.2v 12v ZB2L3 18650 Li-ion Lithium Battery Capacity Tester + Resistance Lead-acid Battery Capacity Meter Discharge Tester
This circuit in order to improve the voltage measurement accuracy, specially designed DC bias, when the terminal is what all don’t pick will display a small voltage, does not affect the actual measurement, if you are short connected with the input terminal (absolute 0V) will display 0. To understand the principle can consult the superposition theorem in electrical engineering.
