Three of these wired in series for 36V. Fished from 740 am til 5 pm. Fished all over spot checking walleye spots and Perch fished a bunch of spots on anchor mode. Back at the dock I checked battery life and was very impressed with the results!

I could not be happier with Vmaxtanks lithium iron batteries (lifepo4), with Vmax service, and in particular with the knowledge and experience of their employee, named Caleb. After speaking with Caleb, he directed me to 4-lithium iron 100 amp hour batteries to meet my power needs to run my equipment. They are far superior to any battery I have ever used to run my equipment. I used to charge my sealed lead-acid batteries once a day, but with the batteries Caleb recommended, and they are 2 1/2 years old now, I charge them once a week, and I could get away with charging them once every two weeks if I needed to. Knowing that they will last me at least 10 years and probably more, and the fact that they are so reliable, the lifepo4 batteries Caleb has recommended puts my mind at ease. Hot days, cold days, it doesn’t matter. The power needed is always there. I have often called upon Caleb to pick his brain, get his best advice to steer me in the right direction and answer questions that I have had over the years. He has always been very patient, kind and extremely knowledgeable. There is not a question I could ask him to which he has not answered. I am thoroughly impressed. Thank you Caleb! I cannot recommend Vmaxtanks enough and Caleb, in particular. Thank you, Vmax & Caleb!

Used the boat with these batteries this weekend at a six hour tournament. I used 10% of the battery thank you.
