Daly BMS gone crazy..Update Opinions
I was charging my 120ah lifepo4 battery yesterday and came in for lunch and saw it shut down..I figured it hit the 3.65 volt cell limit and shut down,I went out to check it and saw this on the Blueto...

This article explains voltages with with charging LFPs between 14.2 and up. Scroll down to the charging part. You can use less than 14.6 ok, with results as explained.
One thing not clear to me, so others will have to explain it, is "full" with LFP. That article says when amps taper to 5% of AH size of battery.
-do you use the "real" size or the "rated" size for ones that are 120AH but rated as 100 and how to know if your own LFP is like that?
- can't you just wait till the BMS goes into its balancing act as your "tell"?
-if your charger has its own "full" indicator should you believe that? Will the charger stop charging based on its own idea of "full"?
Note-the constant voltage setting on a converter like the PowerMax LK model, does not have any "full" marker or stop charging, it is up to you to stop the charge at the time you choose. IMO that is a much better method than using a charger that has its own ideas.
