Whether you have an RV, marine vessel, van, or off-grid property, batteries are an essential piece of your electrical system and ability to store and use power. When your factory-installed system isn’t cutting it anymore, or you’re ready to add more power and capabilities to your current system, determining which batteries are right for you can certainly be a process. With an abundance of battery chemistries, brands, and form factors available on the market today, it can be difficult to sift through the electrical jargon. To assist you with your battery-buying decision, we’ve crafted this Battle Born Batteries Buying Guide that will walk you through each step of the process. Let’s dive in!
First and foremost, you need to determine which battery chemistry would be best suited to your application. When it comes to deep cycle batteries, lead acid and lithium are the primary chemistries available. Although lead acid batteries have been used for decades, the rapid advancement of lithium-ion chemistry over the last few years has led many lead acid users to make the switch. So, what is the difference between the two, and how do you determine if lead acid or lithium is what you need?
While various types of lead acid batteries have historically been the go-to deep cycle power source for years, they pale in comparison to lithium-ion batteries in every category. In addition to being heavier, less powerful, and toxic, traditional lead acid batteries require regular maintenance and monitoring. The ratio of water to liquid electrolyte in these batteries must be carefully maintained to avoid permanently damaging them. Along with ensuring the batteries never drop below a 50% state of charge, lead acid batteries are far from a “set it and forget it” system. Lithium-ion batteries are maintenance-free, meaning you can spend more time doing what you love and less time worrying about your power.
Although they come with a higher price tag that warrants its fair share of “sticker shock,” lithium deep cycle house batteries offer enhanced power, unmatched reliability, and actually a lower lifetime cost. Their higher energy density allows them to emit a longer charge in relation to their size. The increased energy density in lithium-ion allows them to offer higher energy storage per unit mass. This means lithium batteries contain 2-3 times the power in 1/5 of the weight of a traditional lead acid battery. Combined with a 100% depth of discharge, lithium batteries can power more while needing to be recharged less. Plus, let’s not forget their long-lasting capabilities, with 3,000-5,000 deep discharge cycles available offering up to a 10-times longer lifespan than lead acid.
After comparing lithium with lead acid, it’s clear that lithium batteries are the superior choice for deep cycle house power. In a market saturated with lithium batteries, the next challenge is deciding which one to purchase. Despite the term “lithium-ion battery” being used interchangeably, there are actually six different types of lithium batteries. Each type of lithium battery relies on unique active materials and chemical reactions to store energy, and has applications for which it is best suited. When it comes to deep cycle house batteries, lithium iron phosphate (LiFePO4) is the preferred choice due to its durability, long life cycle, and safety.
Once you’ve narrowed your search down to LiFePO4 batteries, another point of differentiation is the cells that make up the batteries. While many other LiFePO4 battery brands are composed of prismatic or pouch cells, Battle Born Batteries use the highest quality cylindrical cells. Cylindrical cells allow for passive cooling, more efficient distribution of internal pressure, and the ability to continue functioning if one cell malfunctions, taking the safety and reliability of Battle Born Batteries to the next level.
In addition to being composed of higher quality components, many still wonder what makes a premium brand, such as Battle Born Batteries, stand out above the rest. Although they come with a higher price tag, Battle Born offers unprecedented excellence that can’t be found in the myriad of imported batteries.

While batteries are an integral part of an electrical system, it’s essential to incorporate a way to charge them. Depending on your application, there are a variety of charging options available.
Regardless of whether you’re hitting the road or spending time on the water, having the option to charge using shore power or a generator never hurts. Whether you plan to use hookups at an RV park or boat dock or recharge at home, shower power is a sure way to quickly recharge your batteries. While other charging methods can be intermittent and complicated, utilizing shore power or a generator is simply reliant on available hookups or having enough fuel.
Even though having this charging option is essential, it should be coupled with another charging source if you want to spend extended time off the grid. Being solely tied to hookups or a noisy, gas-guzzling generator will limit your boondocking capabilities.
For those looking to maximize their time off-grid, solar power is a great charging source. One of our most reliable and abundant energy resources is the sun, which presents an excellent advantage for solar energy. Capitalizing on the renewable energy of the sun, solar panels take in power that moves through a solar charge controller and recharges your batteries. While there are some disadvantages to intermittent solar power at night or on cloudy days, supplementing with more wattage can increase the amount of power your batteries receive.
In addition to being great for RVers and Boaters who spend extended amounts of time away from electrical hookups, solar power is great for residential off-grid systems. These stationary off-grid homes don’t have weight or space restrictions, allowing you to have a large solar array to keep your batteries powered. Not only is solar power easy to generate off-grid, but it is also a clean, green energy source that helps you pursue a more sustainable lifestyle.
Finally, you can recharge your batteries using your vehicle’s alternator. This can be especially helpful for van, overland, and marine applications. With this method, a connection to your vehicle’s alternator, through a regulation device, your house batteries can charge as you drive. Using alternator charging can eliminate the stress that comes from solely relying on solar power. It allows you to simply go for a drive to pull the charge of your batteries up on cloudy or particularly dark days.
The one caveat to this method is ensuring your system is properly designed to avoid damaging your alternator or rig electronics. In order to properly regulate the charge going from the alternator to your batteries you either need a DC-to-DC charger or an alternator regulator. Using a DC-to-C charger, your alternator charges your starting battery, which then charges your house batteries. Alternatively, an advanced alternator regulator like the Wakespeed WS500. This device has a unique ability to regulate based on voltage, current, and alternator temperature and ensure your batteries are only receiving a safe charge.
After investing extensive amounts of time, energy, and money into designing the perfect off-grid power system, you want to ensure it will last for years to come. With varying battery chemistry, their life cycles can vary widely. While some last for decades, others need to be replaced every few years. So, how long do lithium deep-cycle batteries really last?
One of the greatest benefits of LiFePO4 deep cycle batteries is their ability to endure multiple cycles of charging and discharging without experiencing a significant reduction in their capacity. Battle Born Batteries are designed for long-term use and can last up to 10 times longer than lead acid batteries, with 3,000-5,000 deep discharge cycles.
In addition to their long life expectancy, premium battery brands come with sufficient warranties to ensure you’ll always have reliable power. Battle Born Batteries have a ten-year warranty, keeping you on the road far longer than traditional lead acid batteries. This extended warranty guarantees at least ten years of reliable power, making them a more economically viable choice in the long run.
