Anyone know what the trickle charge voltage is on a 12/3000 Multiplus

Having just installed my lithium batteries and my multiplus 12/3000, I'd like to use the trickle charge feature. What is the voltage output? My chassis battery is lead.

Based on what happens on my system the trickle charge has no fixed voltage, it always runs 0.5 to 0.6V lower than the main 12V voltage almost like it has a fixed voltage drop like a diode in the circuit. Therefore the starter battery voltage goes up and down as the main bank goes through absorb and bulk and then drops overnight as the solar goes off. The trickle charge appears to work even with the inverter off.
