Can older Phoenix 48 800 be adjusted voltage wise?

I bought this style unit

https://www.oeko-energie.de/shop1/de/insel-wechselrichter-victron-phoenix800.html

Because it can accept significant higher input voltage (68V) than the successor at 62V or something. It works perfectly with my 60V electric scooter battery if it is charged to only 80 percent or so.

Only trouble is it will drain the battery too far down if unsupervised. Is there any way to adjust the input minimum voltage to around 57V so it shuts off as the more modern units can be adjusted to via app?

Warranty has been voided before so no concern there. Cheers

No, the old ones are very simple and don't have anything to adjust the low voltage shut down.

You could use the Smart BatteryProtect 48V-100A to do that. It is rated for 24-70V and you can adjust the disconnect and reconnect voltage via VictronConnect.

Too easy, thanks mate. Will then manipulate the remote side with a cheapo though as I am concerned the capacitors might fry my BMS at restart with their in rush current and I m stingy on the monies.
