MPPT LifePo4 Liontron Settings

I use a MPPT 100/20 and a Liontron 100ah LiFePo Battery and want to know what the correct settings are. Thank you in advance.

@telefonino, you'll need to get the charge profile specs from your battery manufacturer and then cross-reference with the settings of your particular MPPT. In reality, the default settings are usually fine for most LiFePO4 banks, but it depends entirely upon your manufacturer's recommended charge rates/voltages and which MPPT you have, which you didn't specify.

@telefonino: I have Liotron 3x100Ah, 25,8V and a Victron MPPT 150/35 installed.

Did you get detailed information on charge profile from Liontron?

Thanks, Mathias

The datasheet says:
28.8V absorption voltage and CCCV/IU (constant current constant voltage) charging algorithm.
So I would just select the default lithium profile and change the absorption voltage to 28.8V.
