1st time Lithium

Had trouble with the battery being asleep. If I had read the instructions I would have seen how to wake it up. Called the help center and the next day Nick called me back and was super helpful and answered all my questions. Have used it 3 or 4 times since and it has performed flawlessly.

I heard about Pro Guide on BTL podcast.

Perfect starting battery

I have been testing this battery since March in my 2022 Phoenix 721. I have a Helix 15 at the console and a Helix 15 with Mega360 and a Garmin Echomaps 122 with livescope at the bow. I did not upgrade the wiring in the boat(came with "integrated wiring") and I have not had any decrease in voltage problems during long practice days or tournament days with the aerators on. In my previous boat with a competitors lithium start battery my graphs would shut off during starting by the end of the day and it cost almost twice as much. Pro-guide has developed the perfect lithium starting battery. Do yourself and your boat a favor and get one! Lose weight and lose the worry about low voltage!
