I have a homemade installed battery bank monitor that is installed right next to my entrance door on my OFF-ROAD POPUP using SURE ELECTRONICS meters from ebay/china. I can get a quick check on the Dc voltage real easy having this meter panel here. Just a quick glance everytime I am around the trailer.
I originally had an converter that only had a single mode charger in it which constantly put out 13.6VDC. This got me in the habit of checking battery fluids every couple of weeks and sooner. Since 2008 before I was watching things very close I did lose a battery from boiling out fluids. Now I am using either a WF8945 or a PD9260C smart mode converter but still out habit always keep watching the DC Voltage level and occasionally checking the battery fluids.. I am plugged into my garage 120VAC circuit 24/7 here when not on the road anywhere.
Its just a good idea now for me to always be conscious of what is going on battery wise... I also can switch out my batteries but usually leave them all connected to the converters.
