This DIY 21V Battery Pack Can Discharge 80A?!
I built a custom 21V lithium battery pack with a BMS that can handle insane discharge currents — up to 80A! 🔋
In this video, I’ll show you how I built it, the materials I used, and how it performs under load.
⚙️ Specs:
• 21V (5S2P lithium cells)
• 80A peak discharge
• Custom BMS & nickel strips
Watch till the end for the performance test — it’s shocking! ⚡
