How to Install a LiFePO4 Battery Box with AC Charging & Output Ports


As a survivalist and tech enthusiast, I recently upgraded my lights-out kit by adding a 20Ah LiFePO4 battery. This powerful battery offers long-lasting energy storage and is perfect for off-grid adventures or emergency situations. In this article, I will guide you through the process of installing a LiFePO4 battery box with AC charging and output ports.

Why LiFePO4 Battery?

LiFePO4 batteries have numerous advantages over their counterparts, making them an ideal choice for powering your outdoor adventures. These batteries have a longer lifespan, higher energy density, and are more environmentally friendly. Additionally, LiFePO4 batteries are known for their safety features, such as being non-toxic and non-combustible.

Tools and Supplies

Before diving into the installation process, it is essential to gather the necessary tools and supplies. Here are the specific supplies I used for this build:

  • LiFePO4 battery box with AC charging and output ports
  • Toolbox or similar enclosure
  • Screws and screwdriver
  • Wire cutters and strippers
  • Heat shrink tubing
  • Electrical tape
  • Wiring harness
  • Mounting brackets (optional)

Step 1: Prepare the Toolbox

To install the LiFePO4 battery box, you will need a toolbox or a similar enclosure. Ensure that the toolbox is clean and free from any debris or tools. This will provide a secure and organized space for the battery box.

Step 2: Determine Placement

Carefully decide where you want to position the LiFePO4 battery box inside the toolbox. Consider factors such as accessibility and weight distribution. Remember, this placement will affect how well the battery box integrates into your lights-out kit.

Step 3: Secure the Battery Box

Using screws and a screwdriver, securely mount the LiFePO4 battery box inside the toolbox. If needed, you can use mounting brackets for added stability. Ensure that the battery box is positioned to allow easy access to the AC charging and output ports.

Step 4: Connect the AC Charging Port

The AC charging port is crucial for recharging your LiFePO4 battery. Follow these steps to connect it properly:

  1. Using wire cutters and strippers, carefully strip the insulation from the AC charging wire ends.
  2. Insert the stripped ends of the wire into the designated terminal of the AC charging port.
  3. Use a screwdriver or pliers to tighten the terminal screws, securing the connection.
  4. Optionally, cover the exposed wire ends with heat shrink tubing for added protection.
  5. Once the AC charging port is securely connected, ensure its positioning allows easy access when recharging the battery.

Step 5: Connect the Output Ports

The output ports allow you to power different devices or appliances. Follow these steps to connect them:

  1. Identify the positive (+) and negative (-) terminals on the LiFePO4 battery box and the output ports.
  2. Strip the insulation from the output port wires.
  3. Connect the positive (+) wire to the positive (+) terminal and the negative (-) wire to the negative (-) terminal.
  4. Tighten the terminal screws to secure the connections.
  5. For added protection, cover the exposed wire ends with heat shrink tubing.
  6. Ensure that the output ports are positioned conveniently for connecting devices or appliances when needed.

Step 6: Test the Installation

Before considering the installation complete, it is crucial to test the connections and overall functionality of the LiFePO4 battery box. Connect a device or appliance to the output ports and verify that it receives power. Additionally, plug the AC charger into the charging port and ensure that the battery charges as expected.

Customizing the Battery Box

One of the great benefits of the LiFePO4 battery box is its customization options. Here are a few ideas to personalize your battery box:

  • Paint the toolbox to match your preference or camouflage it for outdoor adventures.
  • Add labels or stickers to indicate the purpose of the AC charging and output ports.
  • Install a voltage meter to easily monitor the battery’s charge level.
  • Attach a handle or strap to the toolbox for easy transportation.


By following the steps outlined in this article, you can easily install a LiFePO4 battery box with AC charging and output ports, enhancing your lights-out kit’s capabilities. Remember to prioritize safety during the installation process and test the connections before relying on the battery box during emergencies or off-grid adventures. Stay prepared and empowered with the latest technological advancements in energy storage.
