If I leave a Blue Smart Charger attached to an AGM car battery but disconnect the mains, can I still monitor the battery voltage over bluetooth?
Also what would the current draw of the charger in this condition be?

@rich1911, this may or may not be somewhat device-dependent... I'm not certain which smart charger you have, but I've tested both an IP65 charger and an IP67 charger on my test bench and bluetooth connectivity is not available on them without mains power; the unit appears to be 100% off until it is plugged into mains, and I register 0 current draw from the battery while either of them are connected without being plugged in.
Thanks for that Justin. Thats too bad. I was hoping to leave the charger attached to the battery permanently and only run out a mains lead if the battery level got too low.
Maybe I'll just buy a blue tooth battery monitor and a dumb battery tender.
@rich1911 this might be -depending on what type of batteries you have- a great use case for the Victron Smart BatterySense?
