Battery Master not trickle charging?

[Kayak Kid]

I have a Battery Master connected between my Fogstar underseat Lithium hab battery and my vehicle battery in my Fiat based Chausson 711 Motorhome. It doesn’t appear to be topping up my vehicle battery and it eventually discharges due to draw from a tracker and alarm. The in-line fuse is fine, but the red light on the Battery Master is not lit - but don’t know if it only lights when topping up! The Lithium battery is fully charged but the vehicle battery keeps discharging. My 230v hook up only charges the Lithium hab battery.

Any ideas on what the issue might be?
