How to set the MPP Solar battery %?

I have an MPP Solar PIP 3024GK device which charges my LiFePo4 batteries up to 27,5-27,6V each day (off grid). However, the MPP tells me this is only 82% of max, and I struggle to find a way to “set 27,5V to max” - I would like for the device to show “100%” when I reach 27,2!

I have read the manual (many times) and tried searching this forum but not found an exact response yet.

Appreciate any help!

are you using a preconfigured battery type or "user defined"?
It could be hardcoded based on battery type so if you switch to user defined (and of course set up all the needed values) it would then use your bulk/float charge voltages to compute percentages...maybe...

Thanks DIYsolar123! I use “User defined” battery type, as I have a couple of 24V LiFePo4 setups in parallel. I have set both the bulk and the float to 27,4V, but when the battery reaches 27,5V, the system still thinks it is “82%”… I tend to agree it is hard coded somewhere or that there is some fancy algorithm of moving averages or something. #scratchingmyhead
