Wie Teste ich meine 🔋 LiFePO4 Akku bzw. die Zellen? #G8N

Here I'd like to share further experiences with the "VaioCore" cells. So you can check what your cells can do. I'll show you how to test the cells and what testing options are available. When purchasing cells, please carefully consider which ones you buy. 420Ah at 5.3 kg would mean an energy density of over 250Wh/kg. As far as I know, that doesn't exist. The state of the art is up to approximately 190Wh/kg. So, cells with 280-310Ah at 5.4 kg are ideal. If you'd like to buy me a beer (https://g8n.eu/Bier) or donate something to our travel fund (https://g8n.eu/Reisekasse), that helps us immensely! Thank you!
