In this list, I will include a 100Ah deep cycle battery that features the LifePo4 chemistry.

The Battery is cost-effective, considering the features it has to offer. Additionally, you’ll also appreciate the fact that the Battery is UL listed and safety certified.

However, since the Battery comes at a lower cost, I have noticed some shortcomings compared to other popular battery manufacturing brands. The major issue that I have noticed is although the Battery is rated as 100Ah, it discharges up to 70 amps at max, while the charge rate is 50 amps.

It means you will have to attach more batteries in parallel if you need more power for larger loads. Moreover, you should also know that the Battery can only connect up to four batteries in parallel. Since the Battery is 12V itself, connecting more batteries to it in a series doesn’t affect its performance.

The best feature about the ExpertPower 100Ah LifePo4 battery is it features BMS (Battery Management System), which means it is equipped with all the necessary protection against any kind of fault or power failure.

Overall, it is a deep-cycle lithium battery that has various strong points and amazing safety features. Moreover, the Battery also comes at a significantly low cost, delivers good life cycles, is safety certified, and is maintenance-free.

So, it is among the best batteries for dry camping to keep powering all the appliances inside your vehicle.

Key Features

How to Choose the Best RV Battery for Dry Camping?

Below, I will go over multiple factors you need to look for when buying the best RV battery for dry camping.

1. Deep Cycle Battery is a Must for RV

The first thing you must know before buying a battery for your recreational vehicle is that it should be a deep-cycle battery.

In simple words, you cannot use a car battery for this purpose. Deep cycle batteries are capable of discharging and recharging quickly. On the other hand, car batteries are only good at providing a powerful burst of power to start the engine.

Deep cycle batteries are manufactured using thick plates while also having dense active material, making them withstand the frequent charge and discharge cycles.

These batteries generate stable and constant power over extended periods. That is why having a deep cycle battery for dry camping is essential.

2. 6V vs 12V Batteries for Dry Camping

A recreational vehicle generally has two types of appliances—ones, which can be run over 120V and others that can only be run on 12V.

An RV comes with a 12V battery or a pair, and they generally power up the 12V appliances.

However, to run 120V appliances, an inverter is required that can convert the battery power to match this number.

It means you will need a 12V battery setup to run the appliances present in your RV. You can also get this through a 12V battery or by combining two 6V batteries in a series.

You should also know that 6V batteries usually last longer while also providing higher charge and discharge rates than a 12V battery.

The 12V batteries, on the flip side, are even more expensive. However, it is up to you whether you go with a 12V or two 6V batteries.

Types of RV Batteries for Dry Camping

Deep cycle RV batteries are available in different classes, and each utilizes different chemistry and has its advantages and disadvantages.

Below, I will highlight these battery types, so you get a clearer idea about which Battery you should choose depending on your dry camping level.

1. Lead-Acid Batteries

Lead-acid batteries are responsible for converting chemical energy into electrical energy and then storing it. Placing the lead-acid batteries indoors is dangerous since they release gas fumes.

These types of batteries are also large and heavy, and they require regular maintenance as well. What makes these batteries even more complicated is that the acid inside the batteries is spillable.

Considering all of this, these batteries might not be one of the best options if you are planning to travel off the grid.

However, if you go dry camping once in a while or stay a day or two, they are among the best since the batteries are known for providing a stable current and are low cost.

2. Absorbed Glass Mat or AGM Batteries

AGM Batteries

Although AGM batteries are essentially lead-acid batteries, they use a fine fiberglass matt that helps absorb the sulfuric acid to make the Battery unspellable.

It means AGM batteries are a better option than lead-acid batteries for dry camping. It is because they have a spill-proof and maintenance-free design.

However, these batteries don’t last as long as lithium-ion batteries, but they have a low, upfront cost.

3. Lithium-Ion Batteries

Lithium ions change their position through an electrolyte, going from positive to the negative electrode while charging and negative to the positive electrode during discharge.

Lithium-ion batteries are available in a range of chemistries. The most common one is lithium iron phosphate, which is more practical and safer.

It means lithium-iron-phosphate batteries are among the best when it comes to the best RV batteries for dry camping.

They don’t only hold the charge efficiently but are also maintenance-free and last for an extended period. These batteries can be charged through any power source, such as solar, generator, or wind.

However, these batteries are also more expensive. If you are considering dry camping or boondocking, they are an excellent and more cost-effective options in the long run.

You just need to add additional batteries to the setup while using an inverter, and you can power up anything on them.

Capacity of the Battery

The capacity of an RV deep cycle battery is calculated in amps (Amp-hour or AH). AH essentially means the amount of electricity a battery can deliver in an hour. Almost all the latest battery models represent an amp-hour and a time value in which it will be discharged completely.

For instance, if a battery label says 200Ah @ 20 hours, it means the battery can run a load of 10 amps uninterruptedly over 20 hours until it discharges completely.

So, if you use only 50 amps, you can keep it running for up to 40 hours.

Now, it is your call to determine the power requirement you want a battery to draw. Almost all the RV appliances come with amps they draw to run.

You can calculate the number of appliance’s amps running at a time to determine the time your Battery will last. RV batteries are available in a wide range of capacities, ranging from milliamp-hours to a thousand amp hours.

Although several deep cycle batteries have a range between 100 to 300Ah, you can increase the amp-hours by adding more batteries to them.

Charge and Discharge Cycles of a Battery

The depth of discharge of a battery means the capacity discharged from a charged battery. This is generally presented in percentage, running from 50% for the majority of lead-acid and AGM batteries to 100% for lithium-ion batteries.

It means if you have a lead-acid battery, you will have only that 50% of capacity at your disposal. You can completely discharge the battery once in a while, but it will reduce battery life.

Charge and discharge cycles also hint at the battery life. This is generally indicated combined with the depth of discharge.

A battery with a 50% discharge rate delivers more cycles than a battery with an 80% discharge rate.

A battery completing a single discharge and charge rate in one day has 500 life cycles, which means you will get 500 days of working out of it.

All of it means a lead-acid battery lasts only a couple of years while a lithium-ion battery can easily serve a decade or more.

Final Thoughts
