resting voltage LFP

I charged my drop-in Lifepo4 battery 100A 24V (25.6V) with built-in BMS without bluetooth with 28.4 V to 100% full. After the charger is switched off, the Victron smart-shunt app gives a resting voltage of 26.6 volts. Is that normal?

@jkb

It depends on if you set that for float or not.

And what you mean by fully charged. How many amps was it drawing at the 28.4v did it hit absorption.

Yes that is about average resting voltage for fully charged LifePo4. (3.325 per cell). It may fall slightly after some time of no charge.
