Difference in bmv712 & 150/75 are settings correct?

Current setup ;

6 x 175w solar panels

MPPT150/75

BMV 712

2 x LifePo4 150ah

3 x Lead acid 105ah


The BMV says SOC 69% but 13.33v, MPPT is 13.49v on float and LifePo says 13.33v (85%)

Appears going into float before batteries are not full. Mppt setting absorp 14.2, float 13.5

What should my settings be to correctly monitor the SOC?

Mixing chemistries and capacity, soc is always going to be guesswork.
