The Lossigy, like other lithium ion batteries, can withstand discharges that exhaust 90 to 95 percent of the battery’s total amp hour capacity, whereas lead acid batteries cut off at this point and won’t go any deeper.

8. Moseworth 24V 60Ah LiFePO4

When it comes to boat battery systems, one 24 volt battery may be preferable to two 12 volt batteries connected in series. This is typically the case because there is simply not enough room for everything on a kayak, canoe, or similar small boat. If that’s the case, this Moseworth model is the most reasonably priced 24 V lithium marine battery available.

In addition to the obvious benefits of saving room and carrying less weight, purchasing a single 24 volt battery can be cheaper than purchasing two 12 volt batteries.

Last but not least, a day’s worth of use out of a 60Ah battery is possible because of the higher voltage.

If you need a 24 volt lithium deep cycle battery but don’t want to break the bank, consider this Ampere Time model. The cost of a single 24V 100Ah battery is much less than that of two 12V 100Ah batteries, so keep that in mind. In this way, you can reap the benefits of a lithium battery system without breaking the bank.

This particular Ampere Time model also features IP6 grade waterproofing, which protects the battery from water damage and allows it to last longer, even when used on a boat. In order to prevent corrosion, however, it is important to wipe it down with a damp cloth after use in a saltwater environment.

9. The 36V 60Ah Moseworth LiFePO4 battery.

You may be surprised to learn that this Flypower, the largest lithium boat battery in this review at 36V and 100Ah, costs less than $1000. The vast majority of competing models in this space are significantly more expensive than this one.

How do lithium marine batteries compare to other options?

While sealed lead acid (SLA) batteries have long been the standard for marine deep cycle applications, in recent years, lithium deep cycle batteries have been increasingly adopted despite their higher cost.

So, why are more and more boat owners switching to lithium boat batteries instead of traditional lead acid ones? In contrast to their lead acid counterparts, lithium ion batteries offer numerous benefits.

Lithium deep cycle boat batteries typically have a lifespan of between 50 and 100 percent longer than their lead acid counterparts. Lithium batteries have a longer runtime per pound of battery weight than lead acid batteries, and they are much lighter.

In addition to this major benefit, lithium deep cycle batteries have a lifespan that is roughly 10 times longer than lead acid batteries because they can withstand a lot more charge/discharge cycles.

Despite the higher purchase price, lithium boat batteries offer significant benefits. Costs are reduced over time with a lithium deep cycle boat battery due to its longer useful life.

Is it really worth getting for your boat a lithium marine battery?

As was previously mentioned, lithium marine batteries have several significant advantages over standard lead acid boat batteries. The length of time you typically spend on the water, however, will determine which battery type is ideal for your needs.

Regular lead acid batteries should suffice for the occasional boat owner who spends no more than a few hours on the water. A lithium marine battery is a better investment if you frequently take your boat out and like to spend the day on the water.

What to look for when purchasing a lithium deep cycle battery

There are a few key considerations when shopping for a lithium marine battery for your boat. To begin, ensure that the battery’s voltage is compatible with that of the device(s) you intend to power. So, if your trolling motor requires 12 volts, you’ll want a 12 volt battery.

Remember that lithium batteries typically have an output voltage that is 1 to 2 volts higher than their nominal voltage. This is especially important to keep in mind when using them for trolling motors, as prolonged exposure to high voltages can destroy the motor.

Battery compatibility with the device you intend to power should be verified by checking the manufacturer’s specifications. Battery over-discharge and voltage peaks can be prevented with the help of a Battery Management System, which some batteries feature.

Second, select a battery amp hour capacity suitable for the duration of use required by your electronic devices. You’ll need more storage space if you like to spend the day on the water as opposed to just a few hours.

Powering trolling motors requires a battery with an amp hour capacity at least equal to the motor’s pound thrust rating. Especially if you plan on using it for an entire day, this is crucial.
