Deep cycle batteries provide reliable energy over long periods of time and have many industrial and recreational uses. Because they’re designed to maintain stable, continuous performance at slower discharge rates, deep cycle battery systems offer a long list of advantageous features.

Lithium-ion deep cycle batteries have particular utility, especially for applications that call for batteries with superior weight, space, and energy density profiles.

This guide explores the many advantages of lithium-ion deep cycle battery systems and their unique applications. Use it to inform your search for the ideal power source for your mobile and off-grid energy generation needs.

What Are Deep Cycle Batteries?

Deep cycle batteries are rechargeable power units specially designed to handle depths of discharge (DoD) in excess of 80% (meaning you can use more than 80% of the battery’s total capacity). Unlike standard rechargeable batteries, deep cycle systems also provide a stable and continuous flow of power during their operational cycles.

Other rechargeable battery units provide power in brief, intense bursts. This leads to uneven performance and requires more frequent recharging.

Lithium-ion deep cycle battery systems have drawn particular attention for their unique technical profiles and performance capabilities. They’re lightweight, have extended lifespans, and are capable of much greater DoD than most alternatives. Other deep cycle battery options include flooded and sealed batteries, absorbent glass mat (AGM) batteries, and gel batteries.

Advantages of Lithium-Ion Deep Cycle Systems

Deep cycle systems come in two main variations: lithium-ion and lead acid batteries. While both support deep cycle functions, lithium-ion batteries offer numerous specific advantages.

For instance, because lithium-ion systems don’t contain fluid that could leak, there’s no need to install or store them in an upright position. Lithium-ion systems are also more than two to three times lighter on average than lead acid deep cycle batteries. Plus, they can maintain a superior performance in extreme temperatures.

Lithium-ion systems have an edge over lead acid deep cycle systems in several ways, such as:

• Capacity: Lithium-ion batteries typically have two to three times more usable power capacity than their lead acid counterparts, even though they take up comparable amounts of space.
• Depth of Discharge: Lead acid batteries tend to have much lower DoD ratings. Some can lag as low as 50% compared to up to 100% provided by lithium-ion systems.
• Recharging Times: Lithium-ion batteries can recharge up to five times faster than lead acid batteries.
• Weight: Lithium-ion batteries are typically two to three times lighter than their lead acid couterparts.
• Lifespan: Lithium-ion batteries can last over 10 years or 3,000 to 5,000 cycles. By comparison, lead acid batteries have lifespans of about two to three years.

How Lithium-Ion Deep Cycle Systems Are Used

You can use deep cycle batteries in any situation in which you need off-grid power for an extended period of time. Because lithium-ion systems offer so many performance benefits, they make a good choice in almost any relevant use case.

For instance, deep cycle systems can power house loads of an RV or provide power to an off-grid residence. Other notable deep cycle battery applications include:

• Marine applications for both house power and trolling motors
• Industrial solar integration (aecurity cameras, traffic signals and more)
• All-Electric APU’s for long haul trucking
• Golf carts
• Material handling

Lithium-ion battery uses also extend to any other area requiring an uninterruptible power supply (UPS). They offer the highest level of dependability of any deep cycle system on the market. Let’s explore some other common uses.

Renewable Energy Systems

Deep cycle battery units are regularly used to store energy created from renewable sources, such as solar or wind power. Solar grids and wind farms can only generate electricity when the sun is shining or the wind is blowing. Any electricity not immediately needed must be retained for later use. Deep cycle systems are uniquely capable of minimizing storage-associated power losses.

Lithium-ion batteries are also ideal for off-grid power systems. With a growing number of people seeking energy independence, deep cycle batteries deliver practical solutions for those who want to reduce or eliminate their reliance on traditional electrical grids.

Mobile Living

RVs frequently use deep cycle systems, with lithium-ion products for mobile living offering many distinct advantages over lead acid alternatives. Deep cycle batteries are also excellent for campers and overlanding rigs, which continue to enjoy resurgent popularity in the 2020s. Overlanding refers to mobile lifestyles of no set duration and with no set destination.

Regardless of whether your mobile living vehicle is an RV, camper, or overlanding rig, a deep cycle battery is your only viable power supply option. Lead acid batteries offer some short-term advantages for budget-conscious mobile lifestyle aficionados, since they have lower up-front costs. But you should carefully consider the performance advantages of lithium-ion batteries, especially regarding their longer lifespans.

Lead acid batteries may cost less initially, but they usually need to be replaced two to four times more often. Over time, cost savings tilt in favor of lithium-ion systems.

Experts recommend evaluating three specific factors when considering deep cycle batteries for mobile living: durability, power capacity, and shelf life. Compared to lead acid systems, lithium-ion batteries offer superior performance profiles across all three categories.
