I installed an isolated Orion DC/DC Smart charger in our Sprinter a while back and we started having issues with the starter battery not too long after (van wouldn’t start). We switched the battery yesterday to exclude that it wasn’t holding charge and checked the voltage of the new one. In the evening it was showing 12.78 V. This morning (ca. 16 hours later) it was at 12.4 V. I’m wondering whether the Orion’s bluetooth/blinking led account for that drop, and if it makes sense to add a switch and turn the Orion off when not using/running the van for longer periods of time. NB: the VictronConnect app indicates that the Orion turns off when the engine does, so it doesn’t seem to be an issue of setting the right shut off voltage. Any help/advice much appreciated!
