I'm thinking of installing a gauge to monitor my 3 batteries. They are AGM 105 amp ones installed a year ago. It is my understanding that they can be damaged if they go below a 60% charge. Your thoughts/suggestions are welcome!
There are lots of fancy options some of which are expensive. However I have been very pleased with a simple volt meter, which is connected to our three AGM batteries and placed on a very visible spot in our galley so both my wife and I see and monitor it. It only cost about $10 on Amazon, and has been perfect for over 5 years. It shows battery voltage to one decimal - - ours charge at 14.3, are charged at 13.4 and we allow it to go down to 12.4 and then recharge with engine or shore power.
Our previous batteries lasted 13 years, and are current ones are doing well at 5 years with lots more to go.
I have a Victron battery monitor, and any similar unit no doubt works fine. It is very useful to know battery charge at a glance, and to be able to see the draw of each appliance. The computations are beyond easy calculation, but the gizmo does it well.
Program The Ah Capacity This article features the older Victron BMV-602. The 602 has been replaced by the BMV-7oo series (700, 702 & 712). Everything in this article is still relevant to the current series of BMV-7xx
Great to hear Christian, thanks. My son in law installed the exact same one in their off road RV and thought the world of it. I thought that the BlueSea one might be 'marine grade' and provide extra protection. Just curious if you installed also the battery connector Loren mentioned.
My big project for the winter was upgrading most of my battery-related systems. Though some of this had long been on the list, the whole lot got moved to the forefront when my old Newmar 25 AC charger died. At about the same time, one of my...
