Lithium vs AGM Batteries

When it comes to powering your motorhome, the choice of battery can be a critical one. Two popular options for deep-cycle batteries in motorhomes are Lithium and AGM batteries. In this blog, we'll compare the pros and cons of these two battery types to help you make an informed decision.

Lithium Batteries

Lithium batteries are becoming increasingly popular in the world of motorhomes. They're lighter, more compact, and have a longer lifespan than traditional lead-acid batteries. Lithium batteries can also be charged and discharged more times than lead-acid batteries, making them ideal for long-term use in motorhomes.


  1. Lighter Weight
    Lithium batteries are lighter than lead-acid batteries, which can help reduce the overall weight of your motorhome.

  2. Longer Lifespan
    Lithium batteries have a longer lifespan than lead-acid batteries, meaning they'll need to be replaced less often.

  3. Higher Energy Density
    Lithium batteries have a higher energy density than lead-acid batteries, meaning they can store more energy in a smaller space.

  4. Maintenance
    Lithium batteries require very little maintenance, making them a convenient option for those who want a low-maintenance battery.

  5. Inverters
    Lithium’s are the perfect choice when It comes to powering inverters as the can supply a much larger discharge without being damaged or compromised by the inverter. 

  6. Solar charging
    Lithium can be fully charged by solar every day making a lithium the better choice if you are wanting to freedom camp of longer periods of time.  


  1. Cost
    Lithium batteries are more expensive than lead-acid batteries, which can make them a less attractive option for some people.

AGM Batteries

AGM batteries are another popular option for motorhomes. They're similar to lead-acid batteries, but instead of using liquid electrolyte, they use a gel-like substance. This makes them more resistant to damage from vibration and temperature fluctuations, making them a good choice for motorhome use.


  1. Durability
    AGM batteries are more durable than lead-acid batteries, making them a good choice for use in a motorhome that experiences a lot of rough roads and conditions.


  1. Weight
    AGM batteries are heavier than Lithium batteries, which can increase the overall weight of your motorhome.

  2. Limited Capacity
    AGM batteries have a limited capacity compared to Lithium batteries, which can make them a less attractive option for those who need a lot of power.

  3. Maintenance
    AGM batteries require special care and maintenance, including monitoring the battery voltage, temperature, and charging process.

In conclusion, both Lithium and AGM batteries have their own set of pros and cons. When choosing between the two, it's important to consider your specific needs and preferences. If you're looking for a lighter, more compact battery with a longer lifespan, Lithium batteries might be the way to go. If you're looking for a durability AGM might be the better option.
