Sorry @Lollo050968 you misunderstood me or I wasn't clear. I was commenting on the actual numbers not why you have the monitors. I have one on my second battery now (not a grenadier).
You need to spend AU$200-300 for a battery monitor that will accurately calculate SOC, anything else is just a rough guide. Ineos will be using a basic shunt somewhere off the starter battery so who knows how accurate it is.
I think it would need a second battery monitor on the auxiliary battery.
I went for 2 BM2 that someone proposed here. Cant find the post, but thanks for comparing some of the cheaper monitor!
I'd charge the batteries first to float with a smart charger. You should be seeing this sort of correlation between voltage and state of charge when batteries are at rest, i.e, vehicle has sat overnight.
There is obviously some disparity between the voltage and the shunt, which leads me to suspect that whatever is draining the battery is not connected through the shunt.
Can you explain that some more, I'm not understanding.
There seems a huge disparity in what the actual voltage readings mean?
The shunt reads the current going in and out of the battery, there may be loads not connected through the shunt so this is possibly why the voltage reads lower than the %Can you explain that some more, I'm not understanding.
Morning.
By the shunt do you mean the Ineos battery monitor connected to the negative terminal? If so how can loads bypass this, there's only the one connection on the terminal?
Yes, the monitor. There may be other powered items that are earthed to the body so not using the common earth. Yes the % is a calculation but in the world of SLA batteries this is way off correct.
So how are they completing the circuit back to the battery if not using this terminal?
