If you wanna do it “right”, run it off the suggested lithium. Having said that, I run 3 of the cheapest bass pro group 27 AGM’s (2 for troll, 1 for crank) and have had no issues running LS off my cranking battery on all day trips for the last 3 years.

The livescope voltage is pass or fail. There’s no benefit at 14v vs 11.5v. If it will turn on and run, the screen looks the same.

Good luck!
