Best Batteries for Campervan Electrical Power System Off gird power

What kind of battery do I need for van life?

If you’re planning a solar camper van project, choosing the right battery is crucial. While there are several types of batteries to choose from, the most popular ones are lead-acid, AGM, and lithium batteries. Each of these batteries has its own advantages and disadvantages, so it’s important to understand them before making a decision.

Lead-Acid Batteries

Lead-acid batteries are the oldest and most widely used type of battery. They are reliable and relatively cheap, making them a popular choice for many people. However, they do have some downsides.


  • Affordable: Lead-acid batteries are less expensive than AGM and lithium batteries.
  • Easy to find: Lead-acid batteries are readily available at most auto parts stores.
  • Good for deep cycling: They can handle deep discharging better than AGM batteries.


  • Heavy: Lead-acid batteries are heavy and can take up a lot of space in your van.
  • Maintenance: Lead-acid batteries require regular maintenance, including checking the water level and cleaning the terminals.
  • Short lifespan: They have a shorter lifespan than AGM and lithium batteries, typically lasting only 2-5 years.

AGM Batteries

AGM (absorbent glass mat) batteries are a type of lead-acid battery that uses a fiberglass mat to hold the electrolyte. They are more expensive than traditional lead-acid batteries, but they have some advantages.


  • Maintenance-free: AGM batteries don’t require any maintenance, making them a convenient option for a solar camper van project.
  • Good for high power applications: They can deliver high power outputs when needed.
  • Longer lifespan: They typically last longer than traditional lead-acid batteries, with a lifespan of around 5-8 years.


  • Expensive: AGM batteries are more expensive than traditional lead-acid batteries.
  • Limited deep cycling: They are not as good as lead-acid batteries for deep cycling.

Lithium Batteries

Lithium batteries are a newer technology that has become increasingly popular in recent years. They are more expensive than lead-acid and AGM batteries, but they offer several advantages.


  • Lightweight: Lithium batteries are much lighter than lead-acid and AGM batteries, making them a great option for a solar camper van project.
  • Longer lifespan: They have a longer lifespan than lead-acid and AGM batteries, typically lasting around 10 years.
  • Good for deep cycling: They can handle deep discharging better than lead-acid and AGM batteries.
  • High energy density: Lithium batteries have a higher energy density than lead-acid and AGM batteries, which means they can store more energy in a smaller space.


  • Expensive: Lithium batteries are the most expensive option, with prices that are often several times higher than lead-acid and AGM batteries.
  • Sensitive to temperature: They are sensitive to extreme temperatures and may require a heating or cooling system to keep them in optimal condition.
  • Safety concerns: Lithium batteries can be dangerous if not handled properly, as they are more prone to thermal runaway and fires than lead-acid and AGM batteries.


Choosing the right battery for your solar camper van project is an important decision that depends on your specific needs and budget. Lead-acid batteries are a reliable and affordable option but require regular maintenance and have a shorter lifespan. AGM batteries are maintenance-free and have a longer lifespan than traditional lead-acid batteries, but they are more expensive. Lithium batteries are lightweight, have a long lifespan, and can handle deep cycling, but they are the most expensive option and require careful handling due to safety concerns. Consider your budget, power needs, and space limitations before making a decision.
