12v problem. Help?!

We've just been away in the van for 4 nights, on the way back yesterday the led lights in the rear were dim and our fridge wasn't working properly.

I guessed this must be due to leisure battery getting low. (Vans got 150w solar panel with victron mppt but it was pretty grey yesterday in Pembrokeshire!). I checked on the victron app and it seemed the Orion dcdc charger wasn't charging whilst driving, app was saying 'input voltage lockout' and 'remote input inactive' which i thought was strange as it has always worked before. The voltage levels in the app seemed ok to me though.

I got home last night and plugged the hookup in, the app was saying that the victron mains charger was at 12.9v and after an hour or so it was on to absorption.

I've left it overnight and just checked before work. Mains charger says battery is charged. Yet non of the LEDs are working properly power up for a split second but then go really dim almost instantly, off 3 individual fuses and switches aswell. USB sockets are same, again off a separate loop.

Any ideas? Only completed the build this summer. Everything has worked fine until now, we've been away about 3 weekends and did 11 nights down the southwest a few weeks back and everything was fine. Hence my confusion.
 
Can you measure the voltage of the battery with the charger turned off ?
