Orion DC-DC discharges the vehicle battery

Hello all,

I have installed severals orion's tr smart isolated dc-dc chargers over the past year, so it's not my first time that I'm talking about this subject. Anyway, this is my second client (rv conversion) that he's complaining that his main (vehicle) battery is completely discharged. I'm trying to figure out why the dc-dc is discharging the main battery..., it's installed, wired & protected according to the manual. I have found this video https://www.youtube.com/watch?v=rDXixCzg6iw but I tell myself that it's a smart device and it must be some of my settings (by default ones according to the battery technology) that are not good ?

Is the buck boost a better alternative ?

Thank you for sharing your experince

Perhaps you can help us to help by sharing the Orion settings, how it's wired and how you're controlling its behaviour.

Hello, like I said before, I'm using only the default settings from the app connect & the wiring is following the manual...

default settings is power supply mode. So by default, and using the included jumper, will cause it to discharge.

Setup the unit properly and use either engine detection or D+.

We're simply guessing here. There are multiple control modes on the Orions and multiple settings. If you don't give us precise detailed information we are all wasting our time.
