I've recently installed a KS 110 ah lithium battery and changed all my device settings to lithium profile. Coming to the end of a 2 week french holiday on an EHU pitch the Moho control panel readings are 15.4 v engine battery and 15.6 hab battery. However, the Bluetooth App reading of the lithium is 14.3v (in standby mode) and the engine battery is showing 13.7 v on the Van Bitz Meta Plus app. The lithium battery is at normal temperature and all systems are working correctly.

Bit worried that these readings indicate something not right. Can anyone explain the 15 volt readings on my Adria control panel?
 
First off I would check the reading at the battery terminals.
 
Does the control panel need to be reconfigured to recognise the new battery? Also could be that the control panel is reading a charging voltage if on EHU. What happens if you disconnect the EHU, if no charging (bar solar of course) do the readings now align...?

Just checked the control panel again and readings back down to 14.2 and 14.3v.
Earlier I did reposition the MH to make it easier to get off the pitch tomorrow so maybe the high readings were something to do with the smart alternator and B2B kit? Anyway, panic over! Thanks for the comments.
