so did you change battery types and go back and not realize that things had reverted? all the numbers you gave above looks like this happened. I wonder if it resets when you take the power off also? Ill have to play with mine and see.

Settings change only in User battery type. In Flooded, Sealed etc they are fixed, you can't change those. I didn't change battery type during the initial test.

Regardless, the app is confusing and has glitches. What you enter in the app, isn't always what is set on the controller. You can change settings directly on the controller by holding the right arrow until it starts blinking. Then you scroll through the screens by pressing the same right arrow once, and change the values by pressing the Up or Down arrow. It doesn't show all the settings - the app has more - and some values that you see on the controller can only be changed in 0.2V increments, not 0.1, and some are unnamed - say, it shows 12.0 and 12.6 (obviously some low-voltage point) but it doesn't tell whether this is LVD or what. App requires manually "finding" the correct Bluetooth every time you turn the phone On, and entering password every time you want to change settings. Same password for all the thousands of users.

It's easy to incidentally change the battery type while doing programming - but this wasn't the case with my 11 V puzzle. Most likely it was a confusion btw the (not clearly named) LVD in the app and the other "Discharge Limit", and also the fridge cutting off way lower than it was supposed to. After you've done and saved the settings by holding the right arrow, they are stable.
