The Renogy 200Ah Lithium Battery is the perfect solution for powering all your off-grid adventures. With its high capacity and efficient energy output, this battery can power all your 12v electrical devices in your RV. 

We’ve installed 2 of these lithium batteries and tested them on our camper. Here’s what we’ve found!

• Durability – The Renogy 200Ah Lithium Battery is built with top-notch materials, heavy-duty casings, and stainless steel terminals. 
• High Capacity – This battery can store up to 200Ah of power at any time, and if you size your system correctly, you don’t have to worry about running out of power while camping in remote places.
• Easy Installation – Installing the battery is extremely straightforward; a simple bolt-together connection system means that even those without technical experience can get up and running quickly – provided the entire system is compatible with a lithium battery.

So if you’re looking for an efficient way to power your campervan or RV off-the-grid, then the Renogy 200Ah Lithium Battery is definitely worth considering!

What We Like

• Can connect up to 8 multiple batteries in parallel.
• The upfront price.

What We Don’t Like

• They cannot be connected in series, so if you need a 24v or 48v electrical system, that’s a deal breaker.
• No terminal covers are included, so they need to be fitted where the posts will always be protected from any risk of being touched. 

The Battle Born, despite having an awesome name, almost makes the top of our list as the best overall lithium battery for RVs. It’s the prominent pick among consumers, and there are many reasons behind the surge in popularity.

This battery is designed to store solar energy in the most efficient way possible, utilizing the technology behind lithium-ion battery manufacturing.

You can expect anywhere between 3,000 and 5,000 cycles, which leaves a pretty large middle-ground. However, even the low end is still a fairly decent rate. 

The Battle Born is a fairly heavy battery. A little bit of planning is called for prior to getting it situated. Since it is designed to run in a series, that planning may involve leaving some room for additional batteries down the road.

The Battle Born has a continuous current of 100aH but a surge current of 200Ah, and you don’t have to worry about damage from discharging, as it’s designed with “automatic cell balance.” 

Although it has a pretty high price tag, it’s often difficult to find a battery with as much performance and longevity as a Battle Born, so it’s a case of getting what you pay for.

What We Like

We love the high-performance rating of the Battle Born 12V and the brains in the battery that manages the entire system, preventing damage to the battery from a variety of accidental usage and environmental factors.

What We Don’t Like

While 31lbs doesn’t sound like a lot, it really is when you’re lugging around a cumbersome battery. The weight definitely has some disadvantages, as well as the high price tag.

Renogy seems to be going for a new type of large RV battery by giving it a significant degree of smarts. Out of the batteries on this list, the Renogy has more built-in smarts than any other, including dual-processors that monitor and control overcharging, discharge protection, short-circuits, temperature, and more. 

It’s also more lightweight and less unwieldy than the Battle Born, and it includes an “auto-balance” function for connecting multiple batteries. However, you have to do so in a parallel, as the Renogy doesn’t support a series. 

The intelligent functions really shine if you have a Bluetooth-connected computer, where you can monitor battery communication, the charging status, and more with the Renogy DC Home App. 

The Renogy is a far more focused 4,000 cycle battery in terms of cycles. However, since it has so many built-in protective features, it’s not likely that it will lose any of those cycles, even if it is mishandled or exposed to extreme temperatures.

What We Like

The smarts that are packed into this battery are seriously next level. There are so many redundant, automated systems, all designed to protect the battery and give you the best performance for the maximum number of cycles.

What We Don’t Like

It’s a little irritating that a smart battery isn’t designed for a series connection, so you have to go the extra mile to build a parallel system. Also, the continuous charge current is half that of the Battle Born at 50A.

It’s such a long name that we thought we would throw the rest of the name, “with 200A BMS for RV Solar,” into the first sentence. It’s a pretty relevant portion, too, because this battery screams, “put me in a solar bank.” 

This is an excellent battery for solar use, and the fact that you can keep it outside with your panels or inside, whichever suits your needs. Either way, you will get 2,560Wh out of this monster since it operates at 200Ah and 12.8V. 

This battery makes a good outdoors battery because of its casing, which is constructed of ABS material and has an IP65 weather rating. That’s good enough for dust, debris, and maybe a light water mist, but it definitely shouldn’t be left out in the rain. 

You can also discharge this battery at 100% with built-in protection against damage from it. That doesn’t mean that you should allow that to happen, just that it has the capability. You will easily get 10 years out of the Amper Time, with 4,000 to 8,000 cycles. It also supports both series and parallel.

What We Like

The physical defenses that this battery has separate it from the group, on top of the fact that it is an incredibly robust battery than can push up to 8,000 cycles. It also comes with multiple built-in system protection and is one of the lowest costing batteries on the list.

What We Don’t Like

It has low-temperature cutoff protection. However, if you ensure that the protection is on, you sacrifice the use of the battery in below-freezing temperatures, as it won’t charge or discharge at those temperatures.

Sure, it’s one of the least capable batteries on our list and one of the lightest; however, not everyone is camping in a massive Class A RV, necessitating monster batteries laid out in larger solar banks. The Miady is the best lightweight battery on this list, and it still manages to pack quite a punch.

The 2,000 cycles limit doesn’t seem like much but considering that it will give you more than five years, so long as you treat it right, it’s still hard to beat. It also has a built-in battery management system that protects against overcharge, discharge, over-current, and higher temperatures despite its small size. 

While it doesn’t support series connections, it can be built into a parallel so you can set up your customized solar bank with ease. In addition, it’s a durable battery, highly rated against leakage, and highly praised for its low footprint.

The battery is designed to operate at maximum power until it is discharged without taking damage, thanks to the built-in BMS. Since it is so small, you can really get creative when setting it up, and it will remain out of the way during operation. 

It also has a high safety rating in terms of leaks, fumes, and explosive hazards because it has a highly stable thermal and chemical process. Overall, it’s a well-put-together battery that will last a long time, even if you put it to hard use, especially in a bank with additional batteries.

What We Like

It’s always nice to see an underdog pull its weight amongst the big dogs. We like the versatility and customization options of this small and easy-to-place battery. It also packs quite a punch in the power department with plenty of longevity for a low-cycle rate.

What We Don’t Like

It’s definitely on the short side when it comes to longevity, but it’s to be expected for a battery that is really made for smaller applications, such as teardrop campers and much smaller RVs.

This is the battery you want as your backup when you’re headed out to Arizona, Nevada, or anywhere with a desert or subtropical climate. Like all of the batteries on this list, the AIMs contain a built-in BMS that’s more sophisticated than any other besides the Renogy.

It comes in three different versions, with the 200Ah monster getting most of the love for larger RVs. Either way your choose, you will get 4,000 cycles. If you opt for the largest one, bring a forklift because it weighs over 60lbs. 

This battery has a constant output voltage, which means that, like the Miady mentioned above, it can operate at full power to the point of 100% discharge without damaging the battery. Furthermore, the BMS system protects it from everything you would expect and cell balancing, fault recovery, and thermal safety fusing.

It works by separating any damaged cells from the operating cells, so you can still get some use out of it, but more importantly, it prevents chain reactions which can cause leaks and explosive hazards.

What We Like

We really like the extra sophistication that went into the built-in BMS. Many batteries keep the battery management system pretty basic, but the AIMS takes it to the next level, challenging Renogy.

What We Don’t Like

It’s not the best battery for cold weather use, and, of course, that makes plenty of sense considering the fact that it holds up so well in the heat.
