1. Battle Born LiFePO4 Deep Cycle Battery – Overall Best Deep Cycle Battery For RV

Check Price

Features

  • Vehicle Service Type: Trailers, vans, boats
  • Terminal: 5/16” x 1”, 5/16” x 1.25”
  • Battery Cell Composition: Lithium-Ion, 4 cells
  • Voltage:12 Volts
  • Unit Count: 1
  • Weight: 29 pounds
  • Dimensions: 12.75 inches long, 6.88 inches wide, 9 inches high

Battle Born Batteries starts this list with their LiFePO4 deep cycle battery. It’ll deliver awesome power with a 200-amp surge output for 30 seconds before switching to a 100-amp continuous output. 

Let’s suppose your system already features a lead-acid battery with a LiFePO4-compatible solar controller battery charger. In that case, this 12-volt unit will serve you well as a drop-in replacement. 

But even if you don’t, this Battle Born battery stands out with its exceptional longevity. You can expect it to last 10-15 years or run through at least 3,000 to 5,000 cycles before it loses part of its capacity. 

WHAT WE LIKE

One thing to love about this Battle Born battery is its lifespan. You can reasonably expect this battery to last you 10-15 years. Another way to look at it is that it’ll run through at least 3,000 to 5,000 cycles before it loses some of its capacity.

To put those numbers into context, 1 cycle is when the battery uses 100% of its energy and then recharges back to its maximum capacity.

Overall, it’s a durable and powerful long-term investment. Once you put it in your RV, you won’t have to worry about it for a very long time.

WHAT WE DON’T LIKE

Unfortunately, this battery is pretty large and heavy. That can be an issue if you prefer things to be compact and lightweight.

PROS

  • Excellent warranty
  • High-performance battery
  • Long-lasting

CONS

  • No cranking power
  • Somewhat heavier than other batteries
  • Requires more space

Features

  • Vehicle Service Type: Trailer
  • Terminal: T11 terminal
  • Battery Cell Composition: Absorbent Glass Mat (AGM)
  • Voltage: 12 Volts
  • Unit Count: 1
  • Weight: 67 pounds
  • Dimensions: 13 inches long, 6.8 inches wide, 8.7 inches high

WindyNation joins this list with its BattaMax AGM battery. Overall, this 12-volt, 100 amp-hour battery will provide you with excellent performance for the price you pay.

WindyNation originally designed this battery for military use. So when you combine that kind of design with the battery’s Absorbent Glass Mat (AGM) technology, what you get is an incredibly robust battery that can still deliver an excellent charge even in extreme hot and cold temperatures.

On top of that, this battery also has quick recharge times, so you can replenish the charge pretty quickly when you turn the engine on or get access to shore power.

WHAT WE LIKE

What we like the most about this WindyNation battery is how well it holds its charge, and also how fast it recharges. Combining those two traits will make for an excellent dry camping experience.

Firstly, you’ll be able to run your appliances for longer without draining your battery. Even if you do, recharging it to max won’t take long.

WHAT WE DON’T LIKE

Sadly, this battery lacks a lot in the portability department. Firstly, it’s pretty heavy at 67 pounds. It doesn’t help that the battery doesn’t have any handles built into it.

So, getting it into your RV is going to be one challenge. But if you ever need to change it out, that will be another problem as well.

PROS

  • Uses Absorbent Glass Mat (AGM) technology
  • Maintenance-free and spill-proof
  • Resistant to excess vibration

CONS

  • No cranking power
  • Difficult to carry around

3. Universal Power Group – Solar Wind Battery – Best For Solar Charging

Check Price

Universal Power Group 12V 100Ah Replacement Battery Compatible with Minn Kota, Minnkota, Cobra, Sevylor trolling Motor

Features

  • Vehicle Service Type: Trailer
  • Terminal: T11 terminal
  • Battery Cell Composition: Absorbent Glass Mat (AGM)
  • Voltage: 12 Volts
  • Unit Count: 1
  • Weight: 67 pounds
  • Dimensions: 13 inches long, 6.8 inches wide, 8.7 inches high

Universal Power Group (UPG) earns its place on this list with its UB121000 model battery. Not only does this unit pack a high capacity of 100 AH, but it also offers a lot of value that comes with it as well.

Firstly, UPG has done an excellent job with the design and build of this model. It’s not as wide as some of the other batteries in this review. Combine that with the fact that you can mount this battery in any way you want, and what you have is a battery that offers much more flexibility in terms of where and how you mount this in your RV.

WHAT WE LIKE

We had to put this battery on the list because of how well it works alongside solar panels. These days, many RV-ers are converting over to renewable energy sources, especially when dry camping. Pair this battery with a couple of solar panels, and you can run your appliances almost forever.

WHAT WE DON’T LIKE

Despite the battery’s weight, the handle isn’t as durable as it should be. So, you’ll have to practice extra caution when moving it around. You don’t want the handle to break while the battery is directly above your feet.

PROS

  • Maintenance-free
  • High-capacity
  • Charges fast with solar panels

CONS

  • Heavy
  • Flimsy handle

  • Voltage: 12 Volts
  • Unit Count:
  • Weight: 129 pounds
  • Dimensions: 20.5 inches long, 9.4 inches wide, 9.4 inches high

Let’s suppose you’re looking for a battery that has twice the output of a standard one and works well in all climates. Well, Renogy has got precisely what you’re looking for.

At 200Ah, this battery has a whopping output that will run pretty much anything you have in your RV. But that’s not the only good thing about this particular unit.

RV-ers wishing to sequence their batteries will find this Renogy model to be a perfect solution. You can connect up to 4 of these batteries in series, allowing you to create an RV system of up to 48 volts.

WHAT WE LIKE

This battery has lots of output and can handle itself well in extreme temperatures. But what we like the most is that this battery is ideal for sequencing.

By connecting up to 4 of these batteries in series, you can build an RV system of up to 48 volts. That’s something that lithium batteries can’t accomplish since you normally can’t build battery banks as big as that.

WHAT WE DON’T LIKE

One issue with this battery is the form factor. The width and height are what you’d expect from a standard RV battery. However, it’s almost twice as long at 20.5 inches.

So, you might have to rearrange a few things in your RV if you’re upgrading from a smaller battery.

PROS

  • Made with corrosion-resistant alloys
  • High-quality build
  • Discharges well in extreme temperatures

CONS

  • Twice as long as standard batteries
  • Heaviest battery in this guide

5. VMAX High-Performance AGM Battery – Most Lightweight And Compact Deep Cycle Battery For RV

Check Price

VMAX V35-857 12 Volt 35AH AGM Battery Deep Cycle High Performance Group U1 Battery Compatible with Small trolling Motors, Backup, wheelchairs and More

Features

  • Vehicle Service Type: Trailer
  • Terminal: 6mm terminal posts
  • Battery Cell Composition: Absorbent Glass Mat (AGM)
  • Voltage: 12 Volts
  • Unit Count: 1
  • Weight: 25 pounds
  • Dimensions: 7.7 inches long, 5 inches wide, 6.1 inches high.

Lastly, we have this VMAX High-Performance AGM Battery. With a small form factor and strong output, this battery will discreetly stay out of sight while keeping your RV appliances running.

Don’t let the smaller-than-average size fool you, though. This heavy-duty battery charges up quickly while producing barely any heat at all.

WHAT WE LIKE

We like how this battery combines some of the best qualities you could hope for in a deep-cycle RV battery. It takes up little space, it holds a substantial charge, and it can keep up with energy-hungry appliances.

WHAT WE DON’T LIKE

Despite all the positives, this battery doesn’t have as sturdy a build as other batteries on this list. Sure, it’s small and light enough to carry around without any problem. However, it might not handle being dropped on a hard surface.

PROS

  • Almost no heat while charging
  • A durable carrier adds to the portability

CONS

  • Not waterproof
  • Not particularly strong or sturdy

Key Difference Between Battery For RV, Campers, And Trailers

With so many deep cycle batteries on the market, how do you decide which one will suit your needs? Well, that depends mainly on the type of vehicle you’re using.

RVs, campers, and trailers all require deep cycle batteries. However, the critical difference between them is how much energy each vehicle type requires.

Here are the key differences you’ll need to understand to choose the best deep cycle battery:

  • Campers are the smallest among all three vehicle types. People often take these vehicles camping for short periods. So, the priority here is likely to be a portable, compact, and lightweight battery.
  • For trailers, people usually park them in trailer parks with easy access to shore power. So, you might not need a battery with such high capacity since you’ll rely more on what’s available nearby.
  • An RV is larger, and it can fit more people. If you have one, you’re likely to be on the road a lot. Both factors mean that the vehicle requires more battery power, which is why it’s a better idea to invest in a heavy-duty battery with a higher capacity.

As you can see, choosing the best battery for your vehicle will depend on how you plan on using it. Once you understand that, making the right choice isn’t so difficult.

RV Battery Types

There are 4 battery types that you need to be aware of.  They are:

  • Flooded Lead Acid (FLA) batteries
  • Gel batteries
  • Absorbed or Absorbent Glass Mat (AGM) batteries
  • Lithium-ion batteries

Gel, AGM, and lithium-ion batteries are popular choices because they’re maintenance-free. However, they do involve a higher upfront cost. That’s especially true with lithium-ion batteries because they offer more power and are lighter.

Flooded Lead Acid (FLA) batteries are cheaper to buy, but you have to maintain them by adding water every 2-4 weeks.

What Voltage Is An RV Battery?

An RV battery in excellent condition will have a voltage of around 12.6 Volts.

How Does A Lithium Battery For RV Work?

Lithium-ion batteries are a relatively new option for RV batteries, compared to AGM models, for example. Overall, these batteries are more efficient than other types, though they used to come with a bigger price tag. These days, Lithium batteries are more affordable than they’ve ever been. 

Lithium batteries function in the same way as AGM models, as long as parts like the solar controller and battery charger come with lithium or LiFePO4 charging profiles.

The main difference with Lithium batteries is in how you charge them while driving. Typically, you’d charge an AGM battery with either VSR or B2B battery chargers. Lithium batteries, however, require a B2B charger but not voltage sensing relays.

Conclusion

All things considered, our choice for the best overall RV battery is the Battle Born 100 Ah LiFePO4 12 Volt Deep Cycle Battery BB10012.

Lithium batteries like these are known for exceeding the performance of other batteries with a higher number of cycles and an even longer lifespan. Unfortunately, they’ve also been known to be more expensive than AGM batteries which have been around for much longer. 

Well, all of that seems to have changed over the past couple of years. These days, lithium batteries have become more affordable, with some even being cheaper than AGM models.
