Are you considering embarking on the exciting adventure of van life? Whether you're planning a weekend getaway or a long-term journey on the road, one of the most crucial decisions you'll make is choosing the right battery for your van.

In the world of van life, two popular options stand out: AGM (Absorbent Glass Mat) and Lithium batteries. Each type has its own set of advantages and considerations, and understanding the differences between them is essential for making an informed decision.

AGM Batteries: Reliable and Cost-Effective

AGM batteries have been a staple in the RV and van life community for many years. These batteries are known for their reliability, low maintenance requirements, and cost-effectiveness. AGM batteries are designed to handle deep discharges and provide consistent power output, making them an excellent choice for those who enjoy off-grid living.

One of the key advantages of AGM batteries is their relatively lower upfront cost compared to lithium batteries. This makes them an attractive option for van lifers who are working within a budget. Additionally, AGM batteries are sealed, maintenance-free, and can be mounted in any orientation, offering flexibility in installation.

However, it's important to note that AGM batteries have a limited cycle life compared to lithium batteries. This means they may need to be replaced more frequently, especially if they are regularly discharged to low levels. Additionally, AGM batteries are heavier and bulkier than their lithium counterparts, which can impact the available space and overall weight distribution in your van.

Lithium Batteries: Lightweight and High-Performance

In recent years, lithium batteries have gained popularity among van lifers due to their impressive performance and lightweight design. Lithium batteries offer a higher energy density, which means they can store more energy in a smaller and lighter package compared to AGM batteries. This can be a significant advantage for van dwellers who are conscious of weight and space limitations.

One of the standout features of lithium batteries is their superior cycle life. These batteries can endure a significantly higher number of charge-discharge cycles compared to AGM batteries, making them a long-term investment for van lifers who prioritize durability and longevity. Additionally, lithium batteries are known for their ability to maintain a consistent voltage throughout the discharge cycle, providing a more stable power supply for your van's electrical system.

While lithium batteries offer numerous benefits, they come with a higher price tag. The initial investment for lithium batteries is typically greater than that of AGM batteries. However, many van lifers find that the long-term performance and lifespan of lithium batteries justify the higher upfront cost.

Luckily, LiTime provides tech driven best value batteries making it possible for van lifers to access high-quality lithium batteries at an affordable price. LiTime's commitment to innovation and efficiency has revolutionized the accessibility of lithium batteries for van life enthusiasts. By leveraging cutting-edge manufacturing processes and advanced technology, LiTime has made it possible for individuals to enjoy the benefits of lithium batteries without breaking the bank.

Detailed Comparison Between AGM VS Lithium Van Life Batteries

Let's explore several crucial factors that can assist you in determining whether investing in Lithium is a suitable choice for your specific type of Vanlife and budget.

1. Usable Energy

Determining the amount of usable energy you can derive from your battery bank is arguably one of the most critical considerations when making your selection.

To understand usable energy, it's essential to comprehend the concept of a 'cycle' in relation to batteries.

A battery cycle refers to the process of depleting your battery and then recharging it (i.e., the duration it takes for a battery to go from 100% to 0%). Depending on your power consumption, this could span over several days. For instance, LiTime Lithium Batteries can endure approximately 4000-15000 cycles.

Lithium batteries have the ability to cycle around 100% of their capacity without compromising their lifespan.

In contrast, AGM batteries are advised not to be drained beyond 50% of their total capacity, as doing so will significantly reduce their lifespan.

What does this signify?

If an AGM battery bank has 400 amp-hours, it is recommended to only utilize 200 amp-hours to prevent diminishing its lifespan. Conversely, a 400Ah Lithium battery bank actually provides around 400Ah of usable battery.

Considering that nothing typically operates at 100% capacity, let's allow for some leeway and assume that the lithium battery operates at 90%.

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 it comes to transforming a van into a habitable space, the weight of your vehicle is crucial for safety reasons. Once you factor in building materials, food, water, clothing, bedding, and more, it's easy to approach the GVWR (Gross Vehicle Weight Rating).

AGM Batteries are notably heavy. Let's examine 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)

or

1 x 12V 300Ah lithium battery = 60.8 lbs

3.Temperature

When comparing AGM (Absorbent Glass Mat) and lithium batteries from the aspect of temperature, there are several key differences to consider:

(1). Operating Temperature Range:

AGM batteries typically have a narrower operating temperature range compared to lithium batteries. They are generally more sensitive to temperature extremes and may not perform optimally in very high or low temperatures. AGM batteries might require additional heating in cold temperatures and cooling in hot temperatures to maintain their performance.

Lithium batteries, on the other hand, have a wider operating temperature range. They can withstand both high and low temperatures more effectively, making them suitable for a broader range of environmental conditions. Lithium batteries are generally more resilient and can perform well in extreme temperatures without requiring as much additional thermal management.

(2). Performance in Extreme Conditions:

In extremely cold temperatures, AGM batteries may experience reduced capacity and slower charging rates. They might also be susceptible to damage if exposed to freezing temperatures without proper insulation or heating.

Lithium batteries are known for better performance in cold temperatures compared to AGM batteries. They can retain their capacity and provide more consistent power output even in sub-zero conditions, making them a preferred choice for applications in colder climates.

(3). Thermal Runaway:

AGM batteries are less prone to thermal runaway compared to lithium batteries. Thermal runaway is a phenomenon where the battery temperature increases uncontrollably, potentially leading to fire or explosion. AGM batteries have a lower risk of thermal runaway, especially when compared to some types of lithium batteries.

Lithium batteries, especially certain chemistries like lithium cobalt oxide, are more susceptible to thermal runaway if exposed to extreme temperatures or if they are damaged. However, newer lithium battery chemistries and designs have implemented safety features to mitigate the risk of thermal runaway.

In summary, when considering temperature performance, lithium batteries generally offer a wider operating temperature range, better cold-weather performance, and resilience in extreme conditions compared to AGM batteries. However, it's important to note that proper thermal management and safety precautions should be taken with any type of battery to ensure safe and efficient operation, especially in varying temperature environments.

4. Warranty

LiTime Lithium batteries are backed by a 5-year warranty, whereas most AGM batteries usually come with a 1-2 year warranty.

5.Cost

What stops most people from purchasing Lithium batteries over AGM is the up-front investment. Fortuantely, LiTime provides tech-driven but best value lithium batteries.

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

Take Fullriver AGM and LiTime 12V 100Ah Group 24 lithium battery as example

2 x 6V 335Ah AGM Batteries made by Fullriver = ~$1100 US ($500~$600 each)

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