Hochwertiger DIY-Akku für SPARFÜCHSE! Schritt für Schritt Anleitung! "Grade A"-Zellen von Tezepower!

In this video, I'll be building a smart DIY PV battery for a storage power plant/PV system. The housing is made of inexpensive OSB wood. I'm using high-quality LiPo cells (Grade A, 280Ah) from Tezepower, which I'll also test extensively in this video, and the battery management system (BMS) is from JK. Have fun watching and building!
