Would you drive a boat without a fuel gauge? Add a gauge for your house battery bank and have your batteries last longer.
A battery monitor should have been the first upgrade I did, lessons learned. I purchased a Victron BMV-712 with temperature sensor. They cost about $240 and take about 4 hours to install.
The battery monitor lets me know the status of our house battery bank. It also is able to predict, based on current electrical loads, how long I have until they are depleted.
Victron battery monitor(s) can be ordered at our Amazon Affiliate site.
