How do Li batts work for charging efficiency anyway? Wets go crazy for heat loss going past 80% SOC on up. AGMs heat up too.
If Li batts have better charging efficiency, then a straight AH counter when charging would be more accurate than with Wets. (The Trimetric has a built -in allowance for heat loss while charging, but it is not expected to fit all batts. You can adjust that if you do enough trial and error work on that for your own set of batts)
Not sure what it means that Li has that slow rise in voltage. I doubt it means poor charging efficiency. ?

LFP are near 100% efficient, take a 100ah out your putting a 100ah back. No long drawn out charging.
As I mentioned in earlier post, I could almost put a stop watch on the amount of time needed to charge just by looking at the monitor and knowing my SOC.

I donโt find it complicated or in need of micromanagement. I charged it fully, set the amp hour capacity and 100% charge on the monitor when I first installed it. The solar charge controller keeps on charging slowly after the monitor reads 100% but the monitor doesnโt go beyond 100%. It has recalibrated itself so 100% means charging has replaced all the amp hours used since it was last fully charged. No adjusting ever. No doubt it is getting less accurate as the battery capacity diminishes but I always know when Iโve got a full charge.
The battery monitor is perfectly easy to use and the only convenient means of knowing how charged the batteries are. The voltage method, including idiot lights, is overly optimistic because it reads the charging voltage for hours after charging has ceased and you think all is well until your batteries die. For me, on our first long trip, it was no heat on a cold morning. Fortunately we were near a town on Vancouver Island that had a Costco store where I could get new batteries. Those batteries I bought in 2011 now seem to be as good as new so I figure the $25 battery monitor is doing its job.
