Battery State of Charge (SOC): What It Really Is and Why It Can Be Misleading
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…
Sodium-Ion Batteries: The Hype vs. Reality
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…
AGM vs. Lithium Batteries
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,…
Why Some Fuses and Fuse Holders Get Hot (and How to Prevent It)
Our technicians at Battle Born Batteries have recently spoken with many customers who are seeing heat build-up at their fuse and fuse holder. If you’re noticing the same thing, it’s worth addressing, because fuses and fuse holders aren’t just “accessories.” They’re critical safety components that help protect both your system…
What Battery Cable Size Should I Use?
Upgrading your RV or marine battery system is one of the smartest ways to gain more reliable power—but it’s also one of the easiest places to make costly mistakes. One of the most common (and most critical) is choosing the wrong battery cable size. Battery cables are the backbone of…
What Is An Electric Fuse and Why Do They Matter?
Electric fuses are an integral part of almost all electrical circuits in our homes, vehicles, appliances, and components that we use every day. But what are fuses exactly? How do they function, and what is their purpose? This comprehensive guide breaks down the science of fuses and explains why they’re…
Can You Put a LiFePO4 Lithium Battery Inside Your Car?
When it comes to lithium batteries in cars, the term can mean a few very different things. Some people think of the massive battery packs that power electric vehicles (EVs), while others are talking about smaller 12-volt lithium batteries meant to replace a traditional starter battery. Lithium systems can even…
Amps, Volts, Watts, and Ohms: Differences Explained in Simple Terms
Amps, volts, watts, and ohms are the four basic concepts you’ll deal with anytime you work with electricity. Together, they describe how electrical energy flows, how much resistance it encounters, and how much usable power is produced. While these terms can feel overwhelming at first, you don’t need an engineering…
What Are Volts? Understanding Voltage in Simple Terms
We all use electricity every day (and night!) for many necessities, luxuries, and comfort items. Still, most of us are relatively unfamiliar with volts, amps, and watts, the basic electricity units. Volts are only one part of the equation, but understanding their place in the equation will take us well…
