Sergent EC50 control panel problem?

[Voodoo_Pirate]

I think maybe my Sergent control panel needs resetting if this is possible?

I noticed the green led lights lighting up for both the SB and LB. The SB is showing as just the yellow leds lit and the LB is showing up to the first green. (So the very top green not lit)

I have since charged my leisure battery via EHU and also charged the SB via a battery charger. Figures shown prior to this via a multimeter were :
SB - 12.02v
LB - 12.66v

And after a good few hours of charging both both now show on multimeter :
SB - 12.52v
LB - 13.01v

I also have a victron battery shunt which shows
SB - 12:58v
LB - 13.03v

However even after the above increases in both battery voltages the Sergent panel has not changed and still shows the SB as still being only up to the yellow led lights, when I’m under the impression a SB of 12.58v at complete idle rest is a good healthy battery voltage?

Or am I way off?

Got a couple of pics of the batterys?

Are they Standard SLA? AGM? EFB+ ?

As all have different rest voltages.

Morning,

I’ll grab some pics later but the LB is just an 110ah AGM and not entirely sure regarding the van’s SB.

I just find it strange that the Sergent control panel hasn’t registered any improvement at all even when this has been checked via multimeter and the victron app.

Well the full reset is easy.

Just disconnect both battery NEG terminals for 30mins... Then reconnect.

I've the same setup and ignore any nonsense the control panel says.

My EC50 seems pretty accurate for both SB and LB.
Is this a new problem or has it been like it since installation?

I’m starting to think it’s just the starter battery that isn’t in the best health, as the Sergent ec50 has now shown an increase in voltage for the LB. This has now gone up from the amber led’s and is showing as up to 1 green led.

It’s just confusing me as the multimeter is showing 12.58v which I thought was healthy.

Don’t forget the EC50 will be measuring any input voltage either B2B or solar, AGM voltages also take some time to stabilise after charging.
The input voltage isn’t necessarily the battery voltage. I can have 14.7v input to my AGM leisure battery from solar or B2B but the AGM leisure battery won’t read more than 12.65v when it’s fully charged.
I would consult the actual manufacturers specification for each battery.
A battery can also show what seems like a healthy voltage but can’t take any load, don’t rely on voltage alone for monitoring the battery state.

Ok, good to know…. Thank you
