FAQ: The discharge level of the 12V batteries with PCM

FAQ: The discharge level of the 12V batteries with PCM ** Question: I keep discharging the 12V battery with PCM. But when the voltage gets to some 11V, the voltage suddenly drops to 0V. Is the battery defective? No, the battery is not defective. The PCM board in side this type of battery will disconnect the out

Simple Digital Voltmeter (range 0 - 30V)

Simple Digital Voltmeter (range 0 - 30V)

The voltmeter allows to measure Voltage from 0 to 30V. For the measurement under 4V requires an external power supply (in range 5 V - 30 V). See the operation manual for examples. How to use:

1) The red wire connect to the (+) battery terminal
