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...

The big lesson I learned buying one 100AH expensive battery that would do the high amp draw I needed it for, was that it turned out that 100AH was not enough for a longer time off grid just running ordinary RV loads.
The trouble was to get a second one of the same brand/type was even more expensive, and in my case, with two batts, now the "high" draw was only half as "high", so i could have just got two ordinary batteries and saved all that money.
So, it could happen with LFPs too if you only got one 100AH and had to get more AH of a bank later. Can you do that with a second cheaper battery not an LFP and mix them? Can you mix LFPs of different brands?
That is why I suggested returning that one in case you have to make any second one the same, and if you don't want a second one of those. Starting over, you can get one you wouldn't mind getting a second one of.
If you did get two, how to monitor them is a question others will know the answer to, or you could get a bigger AH batt in the first place with just one BMS if you might need more AH in the future.
