36V Lithium Batteries

If you’re still using three standard lithium or lead-acid batteries for your trolling motor, you already know the hassles involved in this type of setup. For one, they can weigh down your boat due to their incredible weight. Plus, you might worry about how much charge they have left. After all, the last thing you want is for your battery to fail while you’re still in the water. Luckily, there are better battery technologies around, like LiFePO4 (lithium-iron-phosphate), which is utilized in our 36V lithium battery.

Not just for trolling and marine

When it comes to any application, you will want a more reliable, longer-lasting, powerful, and efficient power source, like our 36v LiFEPO4 battery. This next-generation lithium chemistry is safer and more efficient than others. Plus, it comes with the best built-in features that will protect the battery from damage. One of the best things about it is it can be the perfect marine battery. With the right size, it could replace three standard Group 31 marine batteries.

Our 36v 40Ah LiFePO4 battery has more power than three ~12V +80Ah AGM or lead-acid batteries and offers beyond five times the lifetime of those alternatives. It’s also versatile for other 36v applications, such as warehouse vehicles, RVs, robotics, golf carts, and forklifts.

Increase your boat or vehicle’s efficiency

Weight is a huge consideration for boats and service vehicles. When they are lighter, they can go faster and be more fuel efficient. Plus, lightweight boats can draft shallower, allowing you to go anywhere. Our 36v lithium marine battery with 40 Amp-hours weighs only 35.6 lbs and measures 13 x 6.8 x 8.5 inches, making it lighter and more compact than lead-acid or AGM batteries. One battery is enough so that you can reduce your boat’s weight by around 200 lbs. With this in mind, consider getting a 36V lithium battery instead of connecting multiple 12V lithium batteries in a series.


Now that you know what makes 36V lithium batteries efficient, let’s take a closer look at their specs:

At Lithium Battery Store, our 36V lithium batteries come with 2000 to 5000 life cycles at 80% DoD. With the 36v 40Ah LiFePO4 battery, you get consistent 40 amp-hours and steady power output throughout, thanks to its flat voltage curve. So, the power output won’t significantly drop, even while discharging. All our batteries include an automatic battery management system (BMS) to protect from short circuits, overcharging, over-discharging, and reverse polarity. It’s a feature that also ensures effective temperature protection to increase battery life and performance.

When shopping for a 36V LiFePO4 battery, make sure it has the best warranty terms. At LBS, our batteries have a 2-year factory-backed warranty to cover manufacturer defects within the active warranty timeframe. We will replace or repair it with a remanufactured or new battery if there are any problems.
