Hi guys,
I have a Ducato from 2018. For the starter battery I have a lead battery with 90 ah, and for the supply battery I use 2 AGM batteries each with 90 ah, I connected these AGM parallel.
The Orion-Tr (12/12 V 30 A) I is between the lead and the two AGM batteries.
The problem is, that my starter battery is empty after two days, I don't know why there is a battery drain.
Here are some screenshots, thanks for your help!
