Victron Orion TR Smart DC-DC Charger

[Issywa]

Just installed this and use it to charge my start battery off my house bank. Planning for future migration from FLA to LFP.

I have noticed that it charges fine when under power or on shore power. However, at anchor it draws down the start battery.

I have the engine detection mode enabled. And have input voltage set at 12.6.

Thoughts?

I have a simple on/off switch on the L/H plug and I leave it off unless I need the charger.
