tournament lithium

Tournament Lithium trolling motor series batteries, use only grade A quality components to give our batteries superior performance and longevity. Our tournament lithium is built tough. This 12 Volt 100AH, 1280 WH lithium battery packs a big punch.

Engineered with lithium iron phosphate (lifepo4) technology this battery has twice the power, half the weight, and lasts 4 times longer than a sealed lead acid battery – providing exceptional lifetime value. 100 amp hours of capacity provides a full day of power for high amp draw trolling motors.

The highest quality lithium iron phosphate technology. There are distinct advantages that come with upgrading to lithium batteries on a trolling motor bank. The upgrade removes between 40 -160 pounds of weight from your boat.

With more power onboard, you won’t be worried about ending a day of fishing early because the trolling motor bank is out of power, which commonly happens with lead acid batteries. You get to stay out there longer and use the trolling motor the way it was designed.

The upfront cost of our lithium deep cycle battery is higher than a lead acid equivalent. But when you divide that cost of the life of the battery, our lifepo4 battery is already cheaper than a lead acid battery. When you factor in the cost and time associated with changing the batteries, you really save a bundle when you decide to install a tournament lithium battery bank. At 5000 cycles, most people will have these batteries for 10 years or more.

I'm absolutely blown away by the performance of these batteries. As a guide, I've used a lot of different makes and models over the years. I now have 3 of the 12V 120AH Extreme models, and 2 12V 100AH Flagship models. I've never used a more powerful battery. Super light, amazing performance in the boat, charges fast, and an unbeatable warranty. I can't say enough good things about them!

I purchased and used the 12v 100AH battery with the LED readout on top. One full fishing season in now complete. The battery has so much juice I can use it a few hours a day over a week without a charge on my 16ft boat. I was skeptical of the LED readout as it was always giving such high readings after a day on the water. Can that be? So I often test the voltage with my volt meter for piece of mind. Both my volt meter and the LED read out are the same or within .1 volts. Very nice.

Bought a 60Ah battery at the start of 2021 to power my kayak trolling motor and also as a power source during camping trips. Was used weekly and after multiple charging cycles it still performs flawlessly. Very happy with the purchase and can recommend the batteries to anyone.

I saw Lithium Marine Batteries at the boat show a year ago. I almost fell over when they were asking $1800.00 dollars for one 12 volt 100 ah battery. I latter found a company out of Oakville Ontario that had their Brand Tournament Lithium Trolling motor batteries. I was interested to find out that they have worked on a perfect formula for current trolling motors that include Tournament Lithium Marine batteries in a set of 1 plus charger for 12 volt motors. 2 x 12 volt 100ah for 24 volt trolling motors and 3 x 12 volt 100 amp hour for 36 volt trolling motor batteries. They teamed up with a well know battery charger company out of the USA to make chargers that are specific to charge Lithium batteries perfectly. It also promotes the long life of Lithium Marine Batteries to last 8 to 10 years.

I spent the last 4 months of the open water season putting my 100aH Tournament Lithium battery to the test in my Old Town Predator MK. Between strong river currents, inland reservoirs, and the great lakes - this thing performed. Aside from the bonus of being so light in weight, my favourite aspect is the ability to monitor your remaining aH usage through the Bluetooth app. This is crucial when you depend on power to cover big water. I have had only one unexpected power drop on the water but still trying to determine the culprit between battery, Noco charger, or BMS bluetooth app settings. Either way, Mike has kept up communication since the beginning. Thanks!!!

I purchased 2 of these 24v. They directly replaced the original sla batteries that were fading fast. They last a long time. The down side is the bms. The bms is great for charging (preventing over-charging) but the bms kicks in if i try to run on max power and it shuts the bike down. The bike works well on the lower torque setting but not high. So, be warned, the bms protects the battery but in some situations, it may not be ideal for your usage. Overall a great purchase. The bike runs longer and is still fast, these are way better than sla and worth the price.

Chained two of them for 24v and placed in an older think electric bike. . Good for 14 hrs on full power. Charged with original sla charger. Wish the price was lower...

I concur with the tester that did a drain down test to this battery. I was very surprised to find a capacity of over 10ah on two tests with a remarkably high efficiency of recharge as previously reported. I stopped at 10.1ah since the voltage dropped to 10.2 volts under load at 4.6a drain and i did not want to excessively drain the battery. I bought the battery as a standby electric outboard battery in a sailboat.

I have been using Lithium Marine batteries for a year now. At first I did not realize the difference between Lithium Marine Batteries, and AGM, or lead acid. It was shown to me to buy Tournament Lithium, that over an 8-10 year period, Lithium batteries are actually cheaper to own. They also provide twice the power of lead acid batteries. When I am fishing, I can fish all day long. I don't have to call it a day after 3-4 hours. Tournament Lithium Marine Batteries are definitely worth the cost.

Americans are becoming comfortable with Lithium Marine Batteries. Most of the Pro circuit fishing pro’s now use them. They are 2 x more powerful than lead acid or AGM, but also weight much less. When you're running to specific locations to fish a tournament and at high speeds, the benefit of 150 lbs of less weight makes a difference both in speed and fuel consumption. These batteries are more expensive to buy, but are cheaper to run in the long run. They can last up to 10 years! with over 5000 charges.

I bought a brand new Tahoe this summer and it included a 24 volt trolling motor. I went out 2 or 3 times and was surprised that I was only able to run about 2 hours on this brand new Trolling motor. I spoke with a neighbour who runs them and he recommended Tournament Lithium Marine Batteries to me. He told me that they were made from Iron Phosphate and were very safe. Much safer than L ion batteries. I put in a complete 24 volt battery system including charger, and wow... not only looks great, but what a game changer for me.

Needed reliable and instant power for My fishing kayak. Was referred by fellow kayak anglers to Tournament Lithium. I acquired Batteries for Myself and My fishing partner. Wasn't familiar with Lithium power. Awesome! Put them through a full season..and was thoroughly impressed with the performance. Fished hard and for multiple outings. Never had any issues with power drop off. All the power and reliability I was looking for. Highly recommended 5 stars from Me.
