Flat Battery, Literally! | DIY LiFePO4 Blade Powerwall | Part 1

We go off-piste with our attempt to build a flat(ish) DIY Powerwall using 2nd life BYD LiFePO4 blade cells. These cells are usually used in EV battery packs, so it's an interesting repurposing project.

About Us

Inspired by Leonardo da Vinci, we're two Dads attempting to improve daily life one video at a time. We love tech, problem solving and helping people so we combined all three and this is how our DADvinci channel was born.

We review stuff! Not only that, we share ways to enhance or further improve what we've reviewed. It's easy to complain, but we want to help everyone improve whatever they provide or sell. We attempt to devise practical and sometimes novel use-cases for the products we test.
Do you have a challenge we might be able to help with? Let us know how we can assist and we could be featuring a solution for you in a future video! Enjoy our channel😊
