Born batteries are great for powering up devices like the Raspberry Pi and a range of other Raspberry Pi based gadgets.
But they can also be useful for powering your phone or tablet, too.
Here’s how to make your own.
Battle Born Battery: The BasicsThe Battle Born battery is an upgrade of the battery you can buy on Amazon, it has a larger capacity, and can also charge a mobile phone or laptop.
You can buy these batteries at a range from around £30-£50 for the base model, and £50-£70 for the Battle Born Pro.
They are also available with extra features, such as an IR blaster and a power indicator.
Here are the basics to make one yourself.1.
Make a battery pack2.
Measure the diameter of the cell3.
Drill a hole for the battery pack4.
Connect the battery to the charger5.
Install the battery onto the battery caseThe battery pack will need to be about 6.5mm wide by 2.5-3mm tall by 1.5 inches thick.
Drill two holes for the bottom of the pack, and connect it to the charging base with a 2.1mm socket.
Now you need to connect the battery into the charger.
It can be either a standard USB-C port or a micro USB socket.
If you’re going to be charging a microUSB device, use one that is designed for charging the phone.
It’s best to use a micro-USB charger with a USB Type-C connector, as the USB-Type-C connection will require a USB-A port to connect it.
If the micro-usb connector is not available, you’ll need to use an ordinary USB Type A port.
The micro USB connector will plug directly into the micro USB port on the Raspberry pi.
If there is a micro SD card slot available, plug that in as well.
If you’re buying a microSD card, you may want to choose a micro sd card slot that can accept microSD cards.
