Hello what do you mean with: "Besides, it can be panel mounted. If you need this, please don’t hesitate to contact us." Do you have a picture of that panel mounted version? What purpose has the displayed version (how do you mount it)? And is it compatible to BCP3? Thanks!

Hello, Arne. Thank you for your interest in our products. This board can be used with BCPB3 or BCPB4. You can install this board to your panel with several screws. If you need, we can customize the panel for you. Please note MOQ is required. Have a nice day~

Is there a way to turn off the board when not needed so it doesn't drain battery or should we implement switch on positive pins from battery?

Hi, Andy. Thank you for your interest in our products. There is no turn-off switch on the board. You can add a switch on the “BATTERY” pins. Please see the picture attached. Besides, please use a switch which supports larger current.
