The batteries are marketed to last 10+ years.

This difference is equal to about 82 gallons or $327 of fuel if you average 3.1 MPG over the 253.5 miles. The lithium ion battery set up increased my range to 2619.5 miles (3.1 MPG x 845 gallons) or 253.5 miles more than my previous set up.

My range with my AGM battery set up equaled 2366 miles at full throttle (2.8 MPG x 845 gallons).

A similar load with the lithium batteries showed a slight increase to about 3.1 MPG. My boat loaded down with two people, AGM batteries, 3/4 tank of gas, full live wells, and a moderate tournament load would get about 2.8 MPG at wide open throttle. I have a mercury smart craft gauge on my boat that instantly tells me my fuel efficiency in MPG (Miles per Gallon). I wanted to see if I gained any fuel efficiency at wide open throttle after switching to lithium. The best way to improve fuel efficiency is by taking it easy on the throttle, but when you are in a tournament, it’s hard not to run your boat at wide open throttle.

This equals about $100 of gas per tournament. On average, I use about 25 gallons of gas per tournament. The gas prices these days are ridiculous! Gas prices are almost $4 a gallon in many parts of the country. You can expect at least a 2-3 MPH increase in top end speed. So how did my boat perform with a similar load but with my new lithium ion batteries? Extremely fast hole shot with a top end speed of 74 MPH! The boat consistently ran between 72-73 MPH. My boat loaded down with two people, AGM batteries, 3/4 tank of gas, full live wells, and a moderate tournament load would peg out at about 69-71 MPH depending upon the conditions. Speed means everything to get to these locations before the crowd arrives. If you are a tournament angler you know that the best spots are often the most crowded spots. Top end speed is crucial for beating the competition to the best fishing areas. Of course this is a very simple test, but it does prove that the weight difference will increase how high your boat will sit up in the water column. The results were that my boat with the lithium ion batteries sat approximately 1.5 inches higher in the water column. I then stepped out of the boat and measured the water line again. For this experiment, I sat in the back of the boat where my new lithium ion batteries are located and got my dad to measure the water line on the side of the boat. I weigh approximately 180 pounds or about as much as the weight saved by switching from AGM batteries to lithium ion batteries. There are claims that bass boats will sit up approximately two inches higher in the water column as a result of the weight reduction. Since my boat was now 171 pounds lighter I decided to see if it made a difference in how the boat sits in the water. The final weight difference equals 171 pounds! So was switching to lithium worth it? Let’s take it to the lake and find out! I chose not to mount the charger on-board even though it is much lighter than the Dual Pro.

The lithium ion battery weighs just 28 pounds for a total of 84 pounds for a 36 volt system.

Add 30 pounds from the Dual Pro on-board charger and the total weight increases to a whopping 255 pounds. Each one weighs 75 pounds for a total of 225 pounds. My previous 36 volt system consisted of 3 Sears Platinum Marine DieHard batteries. Shortly after, my lithium ion batteries were on their way! I sent an e-mail message and received a reply within minutes. Their customer service is also top notch. They offer the best prices in combination with the best warranty on the market. I decided to purchase my batteries from Smart Battery, LLC ( ).
