Battery Voltage Monitor Panel

[dselec]

I built and installed a dual-bank battery voltage monitor on my C34 this spring and am very pleased with the results. It is a vast improvement over the low-res analog voltmeter on the Catalina electrical panel. Also, since it monitors both battery banks simultaneously, it can be useful for troubleshooting the system.

Dimensionally, the panel is a drop-in replacement for the old Heart Interface remote panel. To save power, there is an on/off switch for the displays. The voltage inputs are wired to the BATT TEST switch on the electrical panel. Total project cost is about $60.

I can provide Digi-Key part numbers and the panel design file if anyone has an interest in building one.
