Plan B

"Don't believe the hype", they said! "You won't be able to tell the difference", they said! "Waste of money", they said! That's what I get for listening to dock talk. These batteries are the best thing since the shaky head fishing technique. Hole shot faster, no dragging or combined trolling motor battery with my cranking battery towards the end of the day to start my motor, no losing the use of FFS or 360 due to low voltage during tournaments. Fish all day, river current, load boat and check batteries, still at 12.8 volts. Im very pleased with my purchase!

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.
