House Battery When to Fill Water

I have had luck with filling systems that replaced the cap and used a reservoir connected to each cap. The reservoir held about a gallon but I do not see how you could install it in a tight space like under the step. My 2018 36LA has four batteries in the last compartment and the step space is empty.

i consider 12.2 minimum, my inverter shuts off at 12.1, generator will autostart at 11.9

I also use the Pro-Fill system. It's simple to install and use. I needed a adapter e-mailed customer service, had the part within days.
Set up 4 six volts (Decka) Life is good !!!

I can fill 8 6 volt batteries faster, safer and cleaner than you can "EYE BALL IT"
