What are other users saying about this product?

  • Holds a charge – It’s no fun to get a battery that seems to be working great, only for it to suddenly die out on you. With this one, you won’t have to worry about charging it all the time. Some users report going months and months without even needing a recharge!
  • Runs all-day – If you’re looking for something that can consistently function for hours on end, this is an incredible choice. You power lights, equipment, or vehicles from sunup to sundown and do not notice any change in battery quality.
  • Great for Price and Size – It’s not a massive battery by any means, and it’s certainly less expensive than others on this list, but that doesn’t mean it won’t pack a punch. Users are frequently surprised at their modest purchase to find that this battery works stronger and longer than expected.

Common FAQ

What’s the Difference Between Series Battery Wiring and Parallel Battery Wiring?

Knowing the difference between these two systems of battery wiring is paramount if you want to run a battery system of your own. To put it simply, series wired batteries are combined by voltage, and parallel wired batteries are connected by their total capacity (in amp-hours). If you want more voltage, opt for series wired batteries. If you want more capacity, wire batteries parallel. Parallel wiring involves connecting positives and negatives to their respective charges, and series wiring involves connecting opposites to each.

Cabin Storage (Off-Grid) vs. Home Storage (On the Grid)

Everywhere you go, more and more places are being connected by power lines, and more people fantasize about going away and living “off the grid.” What are the main differences between “on-grid” energy storage and “off-grid” energy storage? Let’s go over some main advantages and disadvantages of each.

Grid Storage

  • Tied to an electrical network with nearby residents
  • A secure backup of power that comes from being a part of the grid
  • Any extra energy you have can be sent to the rest of the grid, which can save you money
  • You have to pay for the power you get from the grid, but it’s usually cheaper during rough weather conditions

Off-Grid Storage

  • Not connected to anyone else, no power bill
  • No worry of the grid going down or being charged higher rates
  • Need for battery storage and wired battery systems

Which Charge Controller To Use for a Small Cabin?

Choosing a charge controller is a lot like choosing a wiring system. You’ve got PWM charge controllers that can’t limit their current output and MPPT charge controllers that can. PWM controllers are more energy-efficient, but they can be seriously damaged if they run more amps than they’re designed to. MPPT charge controllers can limit output, meaning you can create as large an array as you want at the expense of efficiency.

If you’re only trying to power a small cabin, we recommend going with PWM. It’s better to have a lot of voltage, especially if you’re only using a small cabin system. Our favorites include:

  • HQST PWM Solar Charge Controller – For only 20 bucks, you get a controller with tons of outlets, a simple display compatible with most batteries.
  • 20A Solar Battery Regulator – This is one of the cheapest controllers on the market. It doesn’t have many ports, but it has some cool features like a built-in time and specific voltage settings.
  • Renogy Wanderer Charge Controller – This is one of the most popular PWM controllers. It has some pretty cool features like an LED display and a solid ability to deliver amps.

How To Turn Stored Battery Power Into 120-Volt AC Appliances?

Suppose you’ve managed to get this far in the home energy process, congratulations! You probably have a good idea of how you’re getting power and how you’re storing it as well. But how do you turn this stored power into usable energy?

That’s where inverters come in. An inverter is a small box that converts direct current energy (from a battery) into alternating current energy (into your home appliances or whatever you want). They come in many different shapes and sizes, so be sure to do your research before picking a setup.

Key Takeaways

  • Choosing a great battery (or battery system) for your small cabin has never been easier. You can find some of the most highly rated options at the click of a button.
  • If you’re not trying to run a vast solar operation, most of your searching can be narrowed down to a big reliable battery, a PWM charge controller, and some self-reliance.
  • Most people living out in a cabin choose off-grid energy, but there are exceptions. No matter what situation you have, great options are abundant.
