the connection errors surely do...

Thanks @houseofancients that gets me past the login screen?
However, still can't get a BT connection.
I've got it turned on in the functions, I have the BT enabled display module, I have Bt running on my iPhone.
More tricks needed ???
... and I'm very close ?

I have found if you have any DIP switches in the "ON" position, it won't connect to the app. Check that the BMS you are connecting to has them all turned off.

Should the SOC be set to 230Ah as well?
You can set it manually. I believe it will also be automatically set if you do a full discharge from full.

I did a full discharge yesterday. Capacity reset to 226Ah but this SOC number stayed at 100
Ah my bad, sorry didn't read it properly. I wouldn't manually reset an SOC personally. Unless I had some other means of measuring capacity like a smart shunt or similar.

I was just wondering what that setting does as it says 100Ah and it hasn't changed.

To my understanding, SOC is supposed to be the current State of Charge at that point in time. So if you know the battery is at 50%, but its reading 60%, then you can manually select 115ah to tell it.
I think the default value is 100ah, and does not update to reflect the actual SOC.
Just my thought. Idk if its true.

Thanks. I'll just leave it at 100Ah because SOC seems to be accurate

Yes, if it is reading correctly, then no need to change it.

Is it OK to have the cell and total voltage alarm at 3.5V and 56V the same as the protection? Or should the alarm be slightly lower than the protection?
Also can I leave recovery voltages default or should they also be lowered?

you can, but better would be what the manual and box states..
do a full charge untill bms cut off, do a full discharge untill bms cut off : pesto you bms is calibrated to the true amp hours

alarm should be below
alarm triggers a 10 amp charge throttle so your bms has a chance to balance your cells

How much lower 3.45V / 55.2V enough?

that ( again) is what i am using

LOL thanks mate?that ( again) is what i am using
Has anyone experienced this? My SOC was showing around 70% and was getting a good charge, no big loads. When all of a sudden my SOC drops to less than one percent and starts beeping with a "Remaining Capacity Protection Alarm"? Even though voltages all show it isn't at 1%?
Also does anyone know how to stop the beeping? ? I've contacted Seplos but as it is Saturday evening right now I don't expect a response until Monday.

I had a similar event and found a bad (intermittent) connection on one of the bms sense wires.
I got lucky and happened to see the cell showing low voltage and upon wiggling the wire, found the bad connection. The sense wire had been extended to reach the terminal and I had done a poor soldering job.
