Best Lithium Batteries for Caravan in Australia

Best Lithium Caravan Batteries

Not all lithium deep cycle batteries are the same. This article is of general nature; always refer to the specific battery manufacturer data sheet and user manual for specifications and information on fitment & usage.

What is the one thing we want to make our free camping experience in a caravan more pleasurable?

More power so we can relax and enjoy some of the creatures’ comforts from home. This is the most common answer, the ability to run our increased number of appliances, whether in a tent, 4X4, RV, Motor Home, Camper Van or Caravan.

Lithium battery technology has made this possible and has become more affordable. As a result, we can have more usable power in a smaller, light and more compact battery storage setup. In addition to having more storage capacity, lithium batteries can easily be recharged quickly by solar panels, a 240V mains power charger, or a DC to DC charger.

Why choose Lithium Batteries for your caravan?

We are finding the best & most popular option in the Australian market for replacing outdated AGM lead acid batteries in 4 X 4 caravans, RVs, camper vans, and camping are the new LiFeP04 lithium iron phosphate batteries.

They are becoming the preferred replacement batteries for caravan setups. As they are more efficient and have a higher cycle life, they are one of the lightest options available, especially where weight is a critical factor.

Leading lithium caravan batteries come in the exact sizing as the standard AGM battery. Therefore, they can drop straight in without modifying the battery box or compartment.

The new slimline lithium batteries addition allows for easy installation and substantial space-saving advantage. In addition, they are light and compact and have a much smaller footprint so they can be mounted in out-of-the-way places.

When going on off-grid adventures, we demand more comfort and with that comes the use of an increased number of appliances. Unfortunately, this significantly strains the old lead acid batteries and vehicles due to the extra weight to carry around.

Benefits of choosing deep cycle lithium over AGM.

  • Reduced weight: They can be up to a third of the weight of the equivalent AGM battery; with two x 12V 100Ah batteries, you can save up to 35kg and have 60% more usable power and energy
  • More efficient: Most Lithium has a minimum of 5,000 cycles when discharging to 50% compared to 500-1,000 with lead acid batteries.
  • More usable energy: Lithium batteries have more usable power, as with the two x 12V 100Ah batteries, you not only can save up to 35kg in weight, but you also have more depth of discharge, to 80%
  • Quick Charging: Lithium batteries have lower internal resistance and can accept a more significant charge. Back to the two 100Ah’s batteries, with a quality lithium charger, you can be fully recharged within 2- 3 hours. Compared to overnight for AGM.
  • Space-saving Slimline: The advantage of the lithium slimline is the ability to be mounted perfectly behind the rear seats of 4WD or in tight areas that are not commonly used.
  • Save Money: Although quality lithium batteries are a significant upfront investment, they will save you considerable money. Not only the higher cycle life but fuel efficiency and the time spent replacing up to 3 to 4 lead acid batteries over their life.

What is a LiFeP04 deep cycle lithium battery, and how do I choose it?

I am endeavouring to keep this brief and in layman’s terms.

Google “Lithium Caravan Battery”, and you get an untold number of lithium batteries on the Australian market with prices varying by thousands of dollars…….where do we start?

First up, they are not like lead-acid batteries. A lead acid battery is like an old draft horse; you keep overworking it until it dies, even though it is inefficient.

A lithium battery is an efficient electrical device with superior energy capacity, lightweight and capable of delivering up to over 3,000 cycles & 80% DOD energy. Its functions are managed by a Battery Management System  (BMS)

This BMS is sophisticated hardware and software that plays a vital role in operating, monitoring and protecting the battery cells.

Standard functions of a BMS:

  • Monitor & control the voltage across the cells.
  • Built-in safety protection from overcharging.
  • Built-in safety protection from over-discharging.
  • Built-in short circuit protection.
  • Monitor the battery temperature.
  • Communications (Bluetooth)

Advantages of a lithium caravan battery over an AGM.

  • Lightweight
  • Recharge up to 10 times faster
  • Longer service life
  • Available in standard battery sizes
  • Constant power delivery
  • Higher performance

We have tried to make choosing a battery easier by rating the most popular deep-cycle lithium batteries sold by Budget Batteries.

Bear in mind there are multi brands on the market. However, we chose these over most other brands because of their quality, customer service and aftersales support.

Frequently Asked Questions

Can I charge my lithium battery with a lead acid charger?

“Do I need a dedicated charger for lithium batteries?” This is a question asked every day by caravaning people. And it gets confusing when there are claims over the internet that you can use any charger to recharge a lithium battery.

First of all, Lithium batteries are nothing like lead acid batteries and not all lead acid battery chargers are the same. If you refer to both datasheets, there are distinctive differences in the charging algorithms.

You really need to do your homework on the specific charger you wish to use, as you can cause damage to your battery if it’s incorrect.

My advice is: Why are you skimping on a proper charger if you invest significantly in quality lithium batteries? Apart from paying for itself in giving you more life out of the batteries, you are not running the risk of voiding your warranty.

No! the lithium batteries mentioned in this Blog are designed for deep cycling caravan batteries and are not intended for starting.

The lithium batteries mentioned in this post are unsuitable under bonnet application. These are designed for the replacement of deep-cycle lead-acid caravan batteries. There are, however, lithium batteries on the market claiming they are for the use of under-bonnet applications

Lithium batteries are similar to their lead-acid equivariant as the battery capacity will be lower when using high-draw appliances. The higher the discharge (Draw), the less capacity or energy available for use.

The discharge rate is the energy you use from the battery over a set time. So, for example. If using a high-draw appliance, then the capacity of the battery will be less than if you had a lower draw over a longer time.

Think of this as your car. If you drive steadily, you will get better fuel economy than driving radically or at higher speeds.

The type of lithium chemistry used in the ones mentioned in this Blog is (LiFeP04) Lithium Ferro (Iron), and Phosphate (LFP), which is the safest lithium-based battery chemistry available. This is very different from the more commonly used Lithium Ion. Lithium Ion uses Lithium Cobalt Oxide. These much more volatile batteries can suffer from thermal runaway, causing fire or explosion.

Batteries using the LiFeP04 are one of the safest ways to provide power. In addition, they can give a consistent source of energy for your off-grid camping trip.

Bear in mind they like all batteries, they are a stored energy source, and you need to take caution. Even the traditional lead acid batteries have been known to explode, causing damage.

LiFeP04 lithium Phosphate Iron batteries do not give off any hydron gases. However, they have an extra layer of protection with the internally fitted BMS, which protects the cell and you when connected.
