Here is where I got my components (for the "Powerwall") from:
https://www.energusps.com/shop/produc...
https://www.ev-power.eu/Winston-40Ah-...

Useful websites which were shown during the video:

In this project I will be creating my own DIY "Powerwall" which is basically just a container filled with batteries and a BMS. Along the way we will learn quite a bit about LiFePO4 cells and about the budget friendly, yet powerful Tiny BMS. At the end you should be able to create your own big and safe battery pack that can be for example used with a solar off grid system. Let's get started!
