Not sure. The app works for speakers and other battery powered stuff as well.
It might be pace used it for Bluetooth coms before they made their own.
The rs232 pin layout is different to the cable I have and I don't have RJ12 plug to re-crimp.
Will order some and test out pbms tools
I am pretty sure if I pushed charge voltage to 58v with 50 amps it will always hit ovp.
But my charge voltage is 55.7 after full it goes down to 55.2.
So yes you are right it will hit ovp. But ill never touch that voltage in my system
