Thinking about embarking on the thrilling adventure of van life? Whether you're gearing up for a weekend escape or a long-term road trip, one of the most important decisions you'll face is selecting the right battery for your van.

When it comes to van life, two battery types are commonly chosen: AGM (Absorbent Glass Mat) and Lithium batteries. Both offer unique benefits and considerations, so understanding the differences between them is key to making the best choice for your journey.

Dependable and Budget-Friendly

AGM batteries have long been a trusted choice in the RV and van life communities, valued for their dependability, minimal maintenance, and affordability. Built to handle deep discharges and deliver consistent power, AGM batteries are a solid option for those who embrace off-grid living.

One of the standout benefits of AGM batteries is their lower initial cost compared to lithium options. This makes them especially appealing to van lifers on a budget. Furthermore, AGM batteries are sealed, maintenance-free, and can be mounted in any position, offering flexibility in installation.

That said, AGM batteries have a shorter lifespan than lithium batteries, meaning they may need to be replaced more often, especially if frequently discharged to lower levels. They are also heavier and bulkier than lithium batteries, which can affect space usage and weight distribution in your van.

Lithium Batteries: Lightweight and High-Performance

In recent years, lithium batteries have become increasingly popular among van lifers for their exceptional performance and lightweight design. With a higher energy density, lithium batteries can store more energy in a smaller, lighter form compared to AGM batteries. This is particularly beneficial for van dwellers who need to conserve space and manage weight constraints.

A key advantage of lithium batteries is their impressive cycle life. They can withstand many more charge-discharge cycles than AGM batteries, making them a durable, long-term investment for van lifers who value longevity. Additionally, lithium batteries are known for maintaining a steady voltage throughout the discharge process, ensuring a more reliable and stable power supply for your van's electrical system.

While lithium batteries offer many advantages, they come with a higher upfront cost compared to AGM batteries. However, many van lifers find that the long-term performance and durability of lithium batteries make the initial investment worthwhile.

Fortunately, LiTime offers high-quality, tech-driven lithium batteries at an affordable price, making them accessible to van lifers. With a focus on innovation and efficiency, LiTime has transformed the availability of lithium batteries for van life enthusiasts. By utilizing advanced manufacturing techniques and cutting-edge technology, LiTime allows individuals to enjoy the benefits of lithium power without the hefty price tag.

Detailed Comparison Between AGM VS Lithium Van Life Batteries

Let’s examine key factors that can help you decide if investing in a lithium battery is the right choice for your van life needs and budget.

1. Usable Energy

One of the most important factors to consider when choosing a battery bank is determining the amount of usable energy it can provide.

To grasp usable energy, it's crucial to understand the concept of a "cycle" in relation to batteries.

A battery cycle refers to the process of discharging and then recharging the battery (i.e., the time it takes for the battery to go from 100% to 0%). Depending on your power usage, this can occur over several days. For example, LiTime Lithium Batteries are designed to last between 4,000 and 15,000 cycles.

Lithium batteries can be cycled up to 100% of their capacity without negatively impacting their lifespan.

In contrast, AGM batteries should not be discharged beyond 50% of their total capacity, as doing so can greatly shorten their lifespan.

What does this signify?

If you have an AGM battery bank with a capacity of 400 amp-hours, it’s recommended to use only 200 amp-hours to preserve its lifespan. In contrast, a 400Ah Lithium battery bank offers close to 400Ah of usable capacity.

Since most devices don’t run at full capacity, let's factor in a bit of flexibility and assume the lithium battery operates at 90% efficiency.

Situation 1: Using AGM

335Ah AGM Battery Bank = 167.5Ah of usable battery

(Keep in mind that 2 x 6v 335Ah actually equates to 1 x 12v 335Ah battery)

Situation 2: Using Lithium Battery

300Ah Lithium Battery Bank = 270Ah of usable battery

2. Weight

When converting a van into a livable space, the vehicle's weight is a critical safety consideration. As you account for building materials, food, water, clothing, bedding, and other essentials, you can quickly approach the GVWR (Gross Vehicle Weight Rating).

AGM batteries are particularly heavy. Let’s take a closer look at the comparison:

#Scenario 1: Fullriver AGM Batteries

2 x 6V 335Ah AGM Batteries = 205.4 lbs (102.7 lbs each).

#Scenario 2: LiTime Group 24 Lithium Batteries

3 x 12V 100Ah Lithium Batteries = 65.61 lbs (21.87 lbs each)

3.Temperature

When comparing AGM (Absorbent Glass Mat) and lithium batteries in terms of temperature performance, there are several important differences to take into account:

(1). Operating Temperature Range:

AGM batteries usually have a more limited operating temperature range compared to lithium batteries. They are more sensitive to temperature extremes and may not function optimally in very hot or cold conditions. In cold weather, AGM batteries might need additional heating, while in hot weather, they may require cooling to maintain performance.

In contrast, lithium batteries offer a broader operating temperature range. They can tolerate both high and low temperatures more effectively, making them suitable for a wider variety of environmental conditions. Lithium batteries are generally more robust and can perform well in extreme temperatures with less need for additional thermal management.

(2). Performance in Extreme Conditions:

In extremely cold temperatures, AGM batteries may experience diminished capacity and slower charging rates. Without proper insulation or heating, they could also be vulnerable to damage from freezing conditions.

Lithium batteries, however, perform better in cold temperatures than AGM batteries. They can maintain their capacity and deliver more consistent power output, even in sub-zero conditions, making them an ideal choice for applications in colder climates.

(3). Thermal Runaway:

AGM batteries are less likely to experience thermal runaway compared to lithium batteries. Thermal runaway occurs when a battery's temperature rises uncontrollably, potentially resulting in a fire or explosion. AGM batteries have a lower risk of thermal runaway, particularly when compared to certain types of lithium batteries.

Lithium batteries, especially those using chemistries like lithium cobalt oxide, are more vulnerable to thermal runaway if exposed to extreme temperatures or if damaged. However, newer lithium battery chemistries and designs include safety features to reduce the risk of thermal runaway.

In conclusion, when it comes to temperature performance, lithium batteries generally provide a wider operating temperature range, superior cold-weather performance, and better resilience in extreme conditions than AGM batteries. However, it is essential to implement proper thermal management and safety measures for any type of battery to ensure safe and efficient operation in varying temperature environments.

4. Warranty

LiTime Lithium batteries are supported by a 5-year warranty, while most AGM batteries typically offer a warranty of 1-2 years.

5.Cost

The main barrier for many people when choosing lithium batteries over AGM is the initial cost. However, LiTime offers technology-driven, high-value lithium batteries that provide an excellent alternative.

Let's compare the costs between an AGM battery and the LiTime Van lithium battery:

For example, let's look at the Fullriver AGM and the LiTime 12V 100Ah Group 24 lithium battery.

2 x 6V 335Ah AGM Batteries made by Fullriver = ~$1100 US ($500~$600 each)=~£904.83 GBP (£411.29–£493.54 each)

3 x 12V 100Ah Group 24 Lithium Batteries made by LiTime =$889.97 (Less than $300 each)=£732.06 (Less than £246.77 each)
