Charging lithium with a constant load.

I have a 100Ah Lifep04 victron smartshunt and victron smart solar 100/20 and 250w solar panel.

I have a travel fridge that is always cycling on at 5-6 amps draw.

My charge profile is user defined at

Bulk/Absorption 14.5V

Float 13.5V

Overnight the battery typically has lost around 27Ah but by mid morning on a sunny day the battery is fully charged and in float stage with 0 volts and amps.

However as the fridge cycles on, the battery remains in float but trickles a little current trying to keep Battery at 100%.

Does this hurt my battery?

Should I use the load side of controller for the fridge or should I change charging profile of the controller?

TIA.

No that will be fine once its in float it will try to keep the battery at the float voltage - nothing to worry about
