Daly BMS App and B+ showing different voltage than output??

[Makr0]

Hey Folks

Hoping this hasn't been covered before, I'm not sure how to form it into a search that gets me any results. I am running 4S 12V 200Amp Dalys.

I am just about to complete my boat battery build which requires sealing the battery case so I figured I'd better check my batteries thoroughly.

I have one battery that on the Daly App reads 13.2v but the completed battery outputs 12.8v (probing B+ and P-). If I Probe, B+ and B- , I get 13.2v the same as the app.

I've tried every reset I can from the app, no change. What are my next steps?

Thanks for your help

if you load or charge the battery, does the issue correct itself?

I’m not sure …. Lol also not sure why I didn‘t think of that.

I’ll check tonight!

I don't know about DALY, but I've seen JBD that report a lower voltage for some reason. It feels like it's some sort of sleep mode.

Alright, no change. I threw a bench charger on it. Again the bms is reading everything correctly but 13.2v with a 4 amp charge come in but is only out putting 12.87v
