Struggle configurating BMV712 + MPPT 75/15 + BlueSmart ip22 with lifepo4

Hello everyone and thanks for your help !


I have a setup with an mppt 75/15 that works well but I decided to change the AGM battery by a LiFepo4 battery and adding a BMV 712.

As the battery requires a special charger I also purchase a BlueSmart Ip22.


I am currently struggling to configurate all the steps, could someone give me a hand?


The battery is a 150ah 12V and I will add here the notebook that came with the battery -brand Ecoworthy-.

I just setup the menus as LifePo4 but I am trying to tune a bit more the menus to be accordingly to the specs of my battery.

Another thing is when I am charging with the BlueSmart it seems to take a lot of time to rise the volts, how can I be sure when the battery will be full? Normally with my AGM battery the way how I will be sure that it is full would be the Float mode. But I am a bit confuse now with the LifePo4

Spec sheet says charge voltage of 14.6V. This should be your absorption setting in the MPPT and IP22. Otherwise looks ok.

Understood, should I also change then the charge load on BMV from 14.1v to also 14.6v ?


Is it normal that the float voltage is at 13.5v ? Thanks for your help
