Depending on the symptoms your furnace is experiencing, you can troubleshoot a non-working RV furnace on your own. This post aims to help you with that process. We’re going to be focusing here on the most typical RV …
When we hear the term “thermal runaway,” it’s generally associated with lithium batteries. But what is thermal runaway, and how (and why) does it occur? We’ve all heard stories about lithium batteries catching fire or exploding in smartphones, laptops, and even electric cars. But what factors lead to this reaction? And is it a danger …
Today we’re investigating the function of a battery management system. Most of us are familiar with lead-acid batteries. They’ve been around since the mid-1800s, so they’re certainly time-tested. But they’re heavy, they require regular maintenance, and even with that, they don’t last as long as newer technology… such as that found in lithium-ion batteries. Lithium …
We’ve never been shy about saying how much we love boondocking. It’s far and away our favorite way to camp, and we’ve long encouraged everyone to try it. One of the main reasons why many people are intimidated by the idea of boondocking is the limitation on power. We get that – we’re fairly big …
Having lived and worked in our RV for close to two decades now, and being the avid boondockers we are, our move to solar was a big one: 600Ah of Lithium battery power, 8 solar panels (with 1,300 Watts of power), and a fully off-grid ready system. But not every RVer needs a system like …
We recently published a post explaining the significance of a battery monitor for your RV. In today’s post, we’re taking a look at five of the best RV battery monitors on the market today, and we’ll share some insight into why these particular monitors are worthy of being described as being among the best. Let’s …
Today’s post is all about the RV solar charge controller. “The what?”, you may ask. This essential component of an RV’s solar power system is seldom the focus when people talk about solar. Solar panels and battery banks seem to get top billing. But the solar charge controller is a critical element of any RV …
One of the chief reasons why we can boondock (camp off-grid) for as long as we do is the ability of our substantial solar array to harness the awesome power of the sun to keep our electrical system running wherever we are. But we’re full-timers (and we’ve been so for very nearly two decades) and …
RV batteries are a critical feature of the RV lifestyle, especially for those of us who need to be connected to technology on an ongoing basis. But RV batteries can also provide the power for lights, refrigeration, heat, water pumps, and other comforts that we’ve all grown accustomed to being integral to RV life. One …
As those of you who’ve followed us for a while know, we’ve got an extensive solar system on our motorhome consisting of a combination of both rigid and flexible solar panels.
