I have an Orion Smart 12/12-30 in charger mode in my car. Since I have it connected to my battery, it is the first time the car fails to start.
Even if it detects motor stop correctly and thus should stop current flowing from the source battery to the input, can it be that this device drains my source battery while having bluetooth on?
I did not see this device flashing any leds when input is disconnected but has fully charged batteries on the output circuit side. Does the device consume it's standby power from the input ciruit?
