[RE-wrenches] SOC and LFP batteries and TriMetric

[Sindelar Solar]

Yes, I just did. Ralph retired last year and I spoke with the new owner. 
In short, little change - use 2% of capacity for amp threshold and set 
CEF to 98% from default 94%. I was also told to stick with the default 
14.1V voltage threshold, but that equates to 56.4V for a 48V system, 
which is above the normal range of these batteries, so I'm reluctant to 
take that advice.

I'm working with Kyle Bolger of Blue Planet on this first installation, 
and will post to the list what I learn that will benefit others.

Thank you, Allan
