I hear you on redundancy, unfortunately my system is 24v.I'm a big fan of redundancy.......I went with two 12V AGM instead of two golf cart 6V batteries in current setup.

I have Gel now and adding new ones to the existing bank is not a good idea. Moving to LiFePo4 will give me that option as I can afford additional batteries. Waiting is getting frustrating, DIY is looking better and better as I keep reading here
