LiFePO4 DIY Battery Builds - made easier with the Seplos Mason kit

LiFePO4 DIY Battery Builds - made easier with the Seplos Mason kit

In a world where the environment is on the forefront of everyone's mind, renewable energy sources like solar power are gaining immense popularity. And why not? It's not just a sustainable choice that benefits our planet, but it also proves cost-effective in the long haul.  

But what about energy storage? Anyone with solar panels will confirm that storing surplus energy is the secret sauce to maintaining a steady supply. That's where the genius of the Seplos Mason kits comes into play. 

What is the Seplos Mason kit and how does it work?

Imagine having the power, literally, to build your own 48V 14.3kWh or 15.5kWh battery for off-grid installations. That's what the innovative Seplos Mason kit offers. It's not just any kit, it's a complete package designed to make the process of building a 48V LiFePO4 battery straightforward and hassle-free. 

And here at Fogstar, we go beyond the ordinary. We're not just purveyors of the classic, stackable Seplos Mason 280. We've also got its dynamic sibling - the Seplos Mason 280L, a reimagined, wheelable version that adds a touch of versatility to your build. 

Does the kit come with LiFePO4 cells?
While our standard kits may not include LiFePO4 cells, we've got your back! We've curated special bundles that include both the cells and the Seplos kit. These bundles aren't just convenient - they're smart shopping, offering you a chance to save up to 15% on your purchases.

You also have the option of Grade A and Grade B busbars, thus giving you a plethora of choice when it comes to picking your cells for the build.

So, how does the Seplos Mason kit work?
The magic lies in its intuitiveness and simplicity. Essentially, it's a self-assembly system that requires no soldering or spot welding. All you have to do is assemble the parts following the Seplos instruction manual (280 and 280L).

  • Step 1: Begin by unpacking the Seplos Mason kit. It contains everything you need, right from the high-quality bus bars, and BMS to the nuts and bolts.
  • Step 2: Following the manual (280 and 280L), stack the cells in the required arrangement to reach your desired capacity.
  • Step 3: Connect the bus bars, BMS and screen as instructed. Each component fits neatly into the next, securing a firm and reliable connection.
  • Step 4: After ensuring all connections are correct and secure, enclose the setup in the case. Then, connect your newly built battery to your inverter and watch it come to life.

How long does it take to assemble a battery using the Seplos Mason kit?

Have you ever wondered how long it takes to assemble a battery using the Seplos Mason kit? Well, the answer might surprise you. It's quicker and easier than you might think! 

The time taken can vary depending on your experience with DIY projects. However, for a first timer, it typically takes around two hours to assemble a 48V 14.3kWh or 15.5kWh battery.

But here's the beauty of it: with each attempt, you get better and faster at it! Practice indeed makes perfect. 

What is the expected lifespan of a LiFePO4 battery built with a Seplos Mason kit?

You're in for a pleasant surprise. An average LiFePO4 battery built using the Seplos Mason kit is known to have a significantly long lifespan. 

That's not all, though. The lifespan doesn't simply end there. Once a battery reaches its 'cycle life', it doesn't abruptly stop working. Instead, it continues to provide about 80% of its initial rated capacity. That's akin to having a battery that's still robust and reliable, even after its so-called 'end of life'. 

What's the secret to such longevity? Two words: quality components. The Seplos Mason kit is crafted with top-notch, high-end components designed to ensure superior performance and longevity. Remember, the longer the battery life, the less frequently you'll need to replace it. Thus, saving you both time and money in the long run. 

There's more. You also play a part in the lifespan of your battery. Proper maintenance and correct usage can significantly extend its life. 

What tools are required to assemble a Seplos Mason kit?

Building a battery with the Seplos Mason kit is a straightforward process but requires some essential tools. The good news is, you've probably got most of these lying around in your garage already! Let's dive into what you'll need. 

  • Hex Key: This is used to fasten the bolts. It's also known as an Allen key.
  • Electric Screwdriver: A staple around every home (Top tip: remember to check the torque of the screws as you go along. These vary with each connection).
  • Insulation Tape: This helps to secure wire connections and prevent electrical shorts.
  • Multimeter: This is a must-have for any DIY enthusiast. It'll help you measure voltage, ensuring your battery build goes according to plan.

Now, you might be thinking, "But I don't have a multimeter!" Don't worry, they're easily found at any local DIY store. And trust me, it's a valuable tool to have on hand for all sorts of projects. 

Can I expand the capacity of the battery built with a Seplos Mason kit?

Without a doubt, expanding the capacity of a battery built with a Seplos Mason kit is not only possible but also incredibly straightforward. The beauty of the Seplos Mason kit is its inherent flexibility, allowing you to customise your battery build to suit your precise needs. If you find yourself running out of battery storage, you can simply build and add more units as required - in fact, you can add up to 16 in parallel.

When building a 48V battery you can choose between a 14.3kWh or a 15.5kWh battery depending on the type of cells you use. If you opt for the 280Ah cells in a 16S1P configuration (using either Grade A or Grade B cells), you'll have a capacity of 14.3kWh. Opting for the larger capacity cells, such as the 304Ah or 305Ah cells (in either Grade A or Grade B) will give you around 15.5kWh of usable power. 

Does the kit come with a BMS?

Absolutely, the kit does come with a Seplos 200A BMS (Battery Management System). This integral component is designed to oversee the operation of the battery, ensuring its optimal performance and long life.

The BMS is a crucial part of any battery build as it helps maintain the health and efficiency of the battery. It does this by managing the charging and discharging processes, ensuring the battery remains within safe operational parameters and protecting it against potential damage like overcharging or short-circuits.

With the Seplos Mason kit, you're provided with a high-quality BMS that's easy to install. This BMS is specifically designed for LiFePO4 batteries, ensuring compatibility and optimal performance. It also comes with a number of pre-loaded CAN inverter protocols - you can take a look at the full list here.

The Bluetooth and Seplos App allows for real-time monitoring of the battery's vital parameters, you can adjust settings and control the performance of your battery right from your smartphone.

So, when you choose the Seplos Mason kit, you're not just getting components for a battery build. You're getting a fully integrated system that ensures the safety, longevity and efficiency of your battery, making your DIY project easier and more reliable.

What is the warranty on a LiFePO4 battery built with a Seplos Mason kit?

When it comes to warranties, we've got you covered. Rest easy knowing that each Seplos Mason kit comes with a 2-year warranty. If you're buying the accompanying LiFePO4 cells from us, these come with a one year warranty.
