Hi All
I run a 130ah Aux battery in my vehicle which is connected to a smart shunt 500a, Orion DC to DC 12/12 30, Multiplus 240v 12v 30a 800w, Smart Mppt 75/30 and a Cebro GX and Display.
Over the weekend camping my voltage dropped as low a little 6.2v even though my system was showing 99% charge level.
I suspected my battery had failed but when I returned home I connected a battery tester which showed a 25% charge level which was after around 5 hours of driving/charging.
I've now fully charged the battery with a separate charger and it's back to capacity and kicking out 13.4v.
So basically I can only ascertain that my smart shunt was showing incorrect charge level and therefore my Victron setup wasn't charging the battery as it should.
Has anyone seen this issue or can offer any suggestions ?
Thanks in advance
