At first glance, the cost of switching to lithium batteries may seem impractical in comparison to lead-acid but when you break down the details, they paint a dramatically different picture.
Long Service Life
Lithium batteries last up to 10 times longer than their lead-acid counterparts. This means that you don’t have to bring in a forklift every couple of years to haul out those absurdly heavy chunks of lead you have at the stern of your boat. It is this same weight that has reduced your fuel economy and your time to plane.
Every pound you add to the boat makes you draft that much deeper and can finally affect the ride and performance. Lithium batteries have 50-60% less weight than lead-acid batteries and the weight savings from switching to lithium batteries can exceed 100 pounds in some cases. This amount of weight taken off your stern will improve both your range and wide-open throttle numbers.
Lithium iron phosphate provides 25-50% higher capacity than lead-acid. All your accessories will be uninterrupted, and you can continue to max out that five fish limit you were working on. You won’t have to worry about anything except coming up with an excuse as to why you couldn’t make it home for your family dinner on time as the sun begins to drop after a full day on the water.
