Hi guys, so I'm scratching my head at the moment for a few things that have been showing on my bmv-712.
1) tonight when I checked via Bluetooth on my battery, it was showing 63% soc, but 11.9V. It is a lead acid battery, 75ah, under bonnet. I double checked voltage, as 11.9V is 40%,not 63%. It was 11.9V. The only thing running is my fridge, and the car was taken out today for a run, which was about 30 mins drive total (2 x 15mins trips) yesterday it wasn't run, and fridge was off. I now have that battery on trickle charge to top it up.
2) when I'm driving I monitor the battery, and the most the bcdc1225d is putting in, even when low voltage is 5A. I've not seen anything above 5A. It goes from say 73% straight to 100%.
3) battery is a century 75ah deep cycle lead, prob 4 months old.
My questions are, should the bcdc be putting in more than 5a when discharged down to say 70%? How do I realign the bmv and battery soc?
System has been wired properly, only battery on battery side of shunt, everything else on load side. Has been running fine for a while, now just seems out of whack.
