Should my Blue Smart Charger IP22 12 | 15 operate when not connected to mains electricity?

Hi. New user and not technically minded. Sorry! My Blue Smart Charger IP22 12 | 15 (3) in my VW van only connects (via Bluetooth) and lights come on when the van is hooked up to mains supply? I was hoping that the system would monitor my leisure battery while I’m away camping but this doesn’t seem possible. Have I been mis-sold this?

Thanks and apologies for my ignorance!

This is a grid-powered device only. It will only work when grid power is connected. It is not able to pull energy from the battery to show any data or to connect via bluetooth.

It is a feature, that you can leave it connected to the battery, and it will not drain the battery over weeks or months. As soon it is connected to grid, it will automatically check the battery and start to charge it.

If you want to check your battery, you have to chose a DC powered device. Could be the BMS in the battery? Or a smart shunt or battery monitor that are only connected via DC power.
