This unit uses a microprocessor to monitor the voltage on 10 batteries. It checks each battery 100 times a second, and if the voltage goes low for more than about 1/2 second, it flags it as a low battery.
The display changes depending on the state of the batteries being monitored. If all is normal, it doesn’t display anything other than an occasional blink of the decimal point to prove it’s still running.
If one or more batteries drops below the low voltage set point, it displays an “L”, If one or more batteries is over voltage, it displays an “H”. (“u” if there was a low bat in the past, but it’s not currently low)
You can press a button on the board to make it display the list of batteries that are/were high or low.
Another button allows you to display the current battery voltages, lowest since last reset, highest since last reset, and Monitor temperature (Degrees C).

These monitors will work with either of the Optional Display units. (MiniDisplay or 8x8 Matrix Display). The advantage of using one of the display units is that they can be put in the cab of your vehicle so you can see what is happening with the batteries while driving.
It is recommended that the Battery Monitor unit is installed in the Battery Box with the batteries, so you aren't running hi-voltage potential wires out of the battery box.
NOTE: The battery monitor must be built for a specific Battery Voltage, this must be specified when ordering. It is also possible to trade the number of batteries for higher voltage precision. If you don’t need to monitor 10 batteries, the unit can be built for fewer batteries, with a better accuracy on the voltage measurement.
Assembled & Tested: Complete Battery Monitor assembled and tested. NOTE on this, there is 1 part that you will have to build yourself. That is the wiring harness to connect the Battery Monitor to the batteries! This is a High Density DB15 (VGA) connector. I provide the plug, but you will need to add the wires. You need to choose the type of plug (crimp or solder) when you order. (see choices below).
Full Kit: All parts, including the case, but the case will NOT have the cutouts and holes pre-drilled.
Bare Kit: Just the PC Boards, programmed CPU chips, and instructions.
