House Battery-Monitor
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. It's like a fuel guage but for your house battery bank.
I don't recommend battery monitors for the engine battery or thruster banks. Instead, go with a simple Victron Battery Sense for them. (Also on the upgrades page).
Victron battery monitor(s) can be ordered at our Amazon Affiliate site.
