This is a joke , I have two Wattcycle 12 volt 100 ah lifepo4 batteries in parallel and the app shows 71% 13.10 volts and 70% 13.10 volt but each cell is 13.27. then mult victron 100 50 charge controller is showing 13.09 volt and my victron smart shunt showed 13.12 volt. Everything was sorta ok before the update and now it's play how much voltage do they really have. Come on Wattcycle fix this crap and yes I charged each battery to full then recalibrated.
