How to change Blue Smart charger advanced settings for Li-on batteries?

I'm using the 24V / 13A Blue Smart IP65 Charger on two 120Ah LiFEPO4 batteries in series. It's working OK but I would really like to tweek the Bulk Absorption up from 28.4V to the 28.8V receommendation from the battery manufacturer. I may also need to change the 2 hour absorption time limit.

However the settings are greyed out (WTF?). Is it possible to chnage these settings somehow?

TIA

Unless you have poor wiring between the charger and batteries, 28.4 with a 2 hour absorption is definitely getting your batteries fully charged.

Make sure you do NOT have temperature compensation enabled.

You can enable advanced settings near the bottom and go to advanced battery settings then tweak them there.

There is also expert mode as well. You can even save the battery profile you create as a custom battery profile.

I had mistakenly assumed "custom" was not for Li-on, but I've now got a custom setup working just as I had hoped.

thanks to @snoobler @Alexandra.
