Batteries don’t “randomly” overheat in healthy systems. Heat is almost always a symptom: a hot environment, an electrical issue (often at connections), or unusually high internal stress from charging/discharging. The good news is that when you understand where the heat is coming from, you can usually prevent it long before it becomes a serious problem.  At Battle Born, our lithium ion battery packs are engineered with heat resilience in mind and designed to respond predictably and safely if overheating occurs.

Battle Born lithium battery safety is built in layers: LiFePO4 chemistry, BMS protection, rugged design, and real-world validation for RV & off-grid use.

Access the full Technical Note: Safety and Design of the Battle Born 100Ah Positive Terminal Download Executive Summary This technical note describes the design and behavior of the positive terminal assembly used in Battle Born 100Ah batteries. It outlines how the terminal functions under normal operation and under sustained fault conditions, and clarifies the conditions required for its protective mechanism to operate as intended. The terminal design is deliberate. It is based on well-understood principles of materials science, electrical contact physics, and thermal behavior, combined to create a passive, irreversible shutdown mechanism that activates under sustained thermal fault conditions. This function serves as a last-resort protective feature, designed to stop current flow before a thermal event can propagate to the...

Not all lithium batteries are built the same. Cell chemistry, mechanical construction, protection electronics, and third-party validation all influence safety.

Choosing the right deep-cycle battery for your RV comes down to fit, capacity, and how you actually use your rig. From weekend camping to full-time boondocking, the battery you choose directly impacts how long you can stay off-grid and how reliably your electrical system performs. This guide breaks down Battle Born’s deep cycle RV battery lineup and explains which options work best for different RV setups, battery compartments, and power needs—so you can choose the right battery with confidence.

Battery state of charge (SOC) describes how much energy remains in a battery at a given moment. In simple terms, SOC is the battery equivalent of a fuel gauge. It's usually expressed as a percentage from 0% (empty) to 100% (full). More formally, battery state of charge is a normalized estimate of the remaining usable capacity of a battery relative to its fully charged state. It reflects the balance between energy added to the battery and energy removed from it. That balance is adjusted for losses, efficiency, and operating conditions to estimate the usable capacity remaining. Although SOC is widely displayed on phone screens, vehicle dashboards, battery monitors, and industrial control systems, it remains one of the most misunderstood battery...

If you pay attention to energy-storage trends, it’s hard to miss the buzz around sodium-ion batteries. Between new product announcements and global supply-chain shifts, many are asking: Is sodium-ion going to replace lithium-based batteries? At Battle Born Batteries, we take innovation seriously. Our in-house R&D department continuously evaluates emerging technologies and explores ways to improve both existing lithium iron phosphate systems and next-generation chemistries. We are genuinely excited about the potential of sodium-ion for certain applications. However, our testing and real-world analysis show that the technology is still far from ready to replace LiFePO₄ in RVs, off-grid homes, boats, vans, or any mobile deep-cycle system. The characteristics of sodium-ion chemistry simply do not align with the performance demands of these...

If you’re shopping for new batteries, you’ve probably seen the debate around AGM vs lithium. On paper, AGM (Absorbent Glass Mat) looks familiar, affordable, and “good enough.” Lithium iron phosphate (LiFePO₄) looks more expensive but promises big gains in performance and lifespan. So which one actually makes sense for RV, marine, and off-grid systems? And is it really worth upgrading to lithium, or will AGM batteries vs lithium batteries be “close enough” in real life? Let’s break down lithium batteries vs. AGM in plain language, then look at what it means for your specific application. These are AGM batteries, they are lead acid chemistry but sealed in a way that they are safer than their flooded acid conterparts. Table of...
