So, I have 2 12 volt Lynx lifepo4 batteries wired in parallel in my trailer that are charged by solar panels on roof using an Epever charger. I am able to access the bms on the batteries using an app on my phone. I noticed that according to the app one battery was at 78 % while the other was in the 90s.
In my stupidity I went into parameters on the higher battery and turned off charging and discharging to let the other one take a charge by itself. Now my problem is that the battery I shut off won’t show up in the app anymore to turn it back on. I know enough to be dangerous obviously. Does anyone know how to access the bms to turn the battery back on?
 
Do a search on Daly BMs I beleive you can turn it on by applying a voltage to the P and B terminals.

On my JK my DMM on diode test was enough to turn it on.
 
Well, I will try anything. My batteries are encased with only + and - . I will physically isolate batteries and see
