Lithium-ion marine batteries are more efficient than lead-acid batteries, weigh less, and can last up to ten times longer. Lithium batteries are a fantastic choice for marine applications since they include all of these advantages.
Size & Weight Reduction
Every boat has a weight limit, and it’s no secret that lowering your boat’s weight iscrucial. Lithium batteries weigh about half as much as lead-acid batteries of the same capacity.
Increased Number of Charge-Discharge Cycles
Deep-cycle lead-acid marine batteries have a charge-discharge cycle life of 500 to 1,000 times. A lithium marine battery, on the other
hand, has a lifecycle of 3,000-5,000 cycles.In addition, the longevity of a lead-acid battery is determined by how well it is maintained. To maximize their performance and durability, lithium-ion batteries require essentially minimal maintenance.
Increased Power Storage
When a lead-acid battery is discharged below 50% of its capacity, it is damaged and its life is shortened. Most lithium battery manufacturers, on the other hand, rate their batteries to allow for an 80 percent depth of drain. The batteries we make can be discharged completely without causing damage. One of the major advantages of lithium batteries is greater power storage. You may just need half the batteries because you normally get almost double the capacity. When you use half the number of batteries and each one weighs half as much as a lead-acid battery, you save roughly four times the weight.
Purchasing a lithium marine battery is substantially more expensive than purchasing a lead-acid battery. Lithium batteries, on the other hand, typically last five times as long as their lead-acid equivalents. Lithium-ion marine batteries are more cost-effective in the long run due to their
extended lifespan and higher efficiency. Additionally, keep in mind that you may only use half as many lithium batteries as you did lead-acid batteries.
Is It Easy to Make the Switch to a Lithium Marine Battery?
Many lithium batteries are drop-in replacements, which means they’re designed to fit in your battery bank like a standard lead-acid battery. However, it isn’t always a simple plug-and-play situation. Additional components may be required to finish your installation.
To get the most out of your inverter and battery charger, you may need to upgrade them depending on your usage and application. Furthermore, because lithium batteries don’t have any warning indicators that they’re about to expire, a battery monitor may be required.
The majority of these adjustments are simple; nonetheless, electrical system mistakes can be dangerous. Please contact a professional if you are unsure about your abilities to make the conversion to lithium marine batteries on your own.
How Long Do Lithium-Ion Marine Batteries Last?
Lithium marine batteries have a normal charge cycle life of 3,000-5,000 cycles. Lithium batteries typically survive 10 years or longer as a result of this.
Are Lithium Batteries Safe on Boats?
Yes, lithium batteries are suitable for marine and boat use. Because lithium batteries are sealed, moisture and even a small amount of water splashing on them will not affect them.
In addition, most lithium batteries include a battery management system built-in (BMS). To avoid damage or thermal runaway, the BMS will identify unsafe conditions and power down the battery.
Is Upgrading Your Marine Battery to Lithium Worth It?
We’ve already said that lithium-ion batteries are significantly more expensive than lead-acid batteries. However, in exchange for the extra expense, you get significant weight loss, better efficiency, increased safety, and a significantly longer lifespan.
When all is said and done, lithium marine batteries are not only cheaper in the long run, but they’re also well worth the money.
