Victron MPPT trickle charging

I have Victron MPPT Smart Solar that is connected directly to my leisure lithium battery.

I would like to trickle-charge the starter battery. I know I could add a battery maintainer like Ablemail AMT-12 Battery Maintainer – Wildebus or similar... but I'm thinking about more simpler solution like just connecting the starter battery to the load output of MPPT.

Does anyone have this set? Is it possible to set the load output on Victron to charge only when there is solar charging on or does it work like this by default? What I would not like it to do is to charge the starter battery when no solar is happening.

Just a idea: mppt 100/20 switched output as inverted "streetlight". Put a diode and fuse (at least a light bulb) in series to avoid stress due to great potential differences.

Look at it via demomode in VictronConnect
