After purchasing it on Amazon, I found that this battery comes with a built-in BMS (Battery Management System) and low charging temperature protection, which is something a similar-priced option like the Ruxu battery lacks.
One of the key specs of the ExpertPower 12V 100Ah battery is its discharge rate of 70 amps and continuous charge rate of 50 amps. When connecting to a large inverter, it’s essential to understand the maximum continuous discharge rate and match it with the inverter’s power requirements. If necessary, you could connect multiple batteries in parallel to meet your energy needs.
I performed an initial capacity test to evaluate its performance. Charging it, I noticed about 30 amps were going into the battery, which is a good sign. After conducting a maximum load test, I pulled 9 minutes of continuous use and 5Ah of power, which was within acceptable limits.
Running the battery to its depletion, I ended up with 110Ah and 1410Wh output — roughly 10-11% more than what the manufacturer advertised. This was impressive and showed that the ExpertPower 12V 100Ah could deliver more than expected.
I then tested the battery in extreme conditions by placing it in the refrigerator. While I anticipated it would stop charging due to the cold, it continued charging. This was a clear sign that the battery doesn’t have low temperature charging protection, which is a downside. However, a Victron solar charge controller would take care of this issue by preventing charging in low temperatures.
Despite the lack of low temperature protection, the ExpertPower 12V 100Ah is solidly built with well-made cells, connections, and BMS. In terms of performance, weight, and longevity, this is a top-tier budget-friendly RV battery. While it does lack some advanced temperature protection features, it’s still an excellent option for most applications, especially considering its cost-effective price point. Overall, I highly recommend it for RV users, especially if you’re not worried about extreme cold conditions.
Pros
- Excelled in capacity test
- Lightweight design
- Outstanding performance for RVs and campers
- Provides 10–11% more power than advertised

How to Choose an RV Battery – Buying Guide
After hours of research, testing, and collecting data, we’ve compiled not just a list of the top 10 best RV batteries, but also a comprehensive guide to help you make an informed purchasing decision. Here’s a breakdown of the different types of RV batteries to consider before you make your choice:
Types of RV Batteries
Flooded Batteries:
These are the most common type of wet-cell batteries. Flooded batteries are affordable, durable, and widely available. However, they require regular maintenance and have a shorter lifespan compared to other types. One downside is that they don’t perform well under heavy vibration.
AGM (Absorbent Glass Mat) Batteries:
AGM batteries are sealed lead-acid batteries that require minimal maintenance and are highly reliable. They are a great option if you plan to live off-grid. However, they do have a major drawback—they don’t perform well in cold climates, which limits their effectiveness in certain environments.
Lithium Batteries:
Lithium batteries are considered ideal for RV users due to their long lifespan, durability, and high reliability. They are powerful, vibration-resistant, and work in extreme climates, including freezing temperatures. Though more expensive upfront, lithium batteries are a great long-term investment due to their extended cycle life and low maintenance needs.
Our list of the Top 10 Best RV Batteries will guide you in selecting the best option based on your specific needs, whether you’re looking for affordability, reliability, or all-weather performance.
Weather and Cold Conditions:
When choosing an RV battery, it’s crucial to consider how it will perform in cold weather. Different battery types have varying levels of resistance to freezing temperatures and efficiency in harsh conditions. Here’s a breakdown of how different types of batteries handle the cold:
AGM Batteries
Some AGM batteries, like the Optima RedTop, are designed to handle cold weather. With 800 cold-cranking amps, these batteries can power your RV in freezing conditions, though they still might not be as efficient as other types in extreme cold.
Gel Batteries
Gel batteries are excellent for cold climates because they are less prone to freezing compared to other lead-acid batteries. They can withstand lower temperatures without significant performance loss, making them ideal for winter RV adventures.
Lead-Acid Batteries
Traditional lead-acid batteries generally do not perform well in cold temperatures. Their capacity and efficiency can drop dramatically in freezing conditions. If you plan on using a lead-acid battery in cold climates, it’s recommended to use battery compartments with heating pads to maintain performance.
Lithium Batteries
Lithium batteries, such as the Chins 12V 100Ah or Zoom batteries, perform exceptionally well in cold conditions. However, they do require a bit of pre-heating before charging, so they may need to be brought to room temperature before charging to ensure optimal performance. Despite this, lithium batteries are still one of the best options for cold-weather use due to their long lifespan and high efficiency.
Battery Management System (BMS)
When choosing a battery for cold weather, always keep the BMS (Battery Management System) in mind. A BMS protects the battery from both high and low-temperature charging, ensuring that it operates safely and effectively even in extreme temperatures. Most modern batteries come with a built-in BMS, but it’s always a good idea to double-check.
Cost
While cold-resistant batteries like lithium or gel options offer excellent performance in winter, they often come at a higher cost. However, their long lifespan and reliability in extreme conditions make them a worthwhile investment for those who frequently travel in colder climates.
Battery Size
When choosing an RV battery, the size matters a lot, especially when it comes to weight and space. If you’re like me, you probably don’t want to deal with a bulky, heavy battery. It’s best to go for a lightweight and compact battery that fits your RV’s available space. Instead of purchasing one large battery, consider opting for 2 or 3 smaller capacity batteries to meet your needs. This way, you avoid the hassle of dragging around a heavy unit, and it gives you flexibility in case you need to expand your power setup later.
Power Capacity
The power capacity you need depends on how many appliances you plan to run in your RV. While every situation is different, 200Ah is a good rule of thumb for most RV users. It provides enough power for emergencies or extended off-grid trips. Additionally, combining a 12V setup with solar panels can help ensure that your battery stays charged, even when you’re in remote locations without access to electrical hookups.
Lifespan
Battery lifespan is crucial when considering long-term costs. Lead-acid batteries generally last around 3 to 5 years, but lithium batteries can last up to 10 years, making them a better investment in the long run. Even though we don’t typically use our batteries for the full lifespan, going for lithium batteries is a smart choice for durability and longevity. To extend the life of any battery, be mindful not to overtax it or consistently drain it to 0%. Proper maintenance will help it last longer and function more efficiently.
