Make a High-Capacity Li-Ion Battery for Your FPV Plane | 4S 21700 Pack Build

In this video, I walk through the process of building a custom 4-cell 8400mAh Li-Ion battery pack using 21700 cells, designed specifically for long-range fixed wing RC aircraft. I'm fairly new to this aspect of the hobby, so please proceed with caution and use this video as a reference or guide — not a professional tutorial. I plan to build more battery packs in the future and share my experiences along the way. ✅ When building your own Li-Ion packs, it's essential to: Choose the right cells for your application (voltage, capacity, discharge rate) Use the proper tools for spot welding, soldering, and testing Be aware of the safety risks involved — Li-Ion cells can be dangerous if mishandled ⚠️ Disclaimer: Only attempt battery building if you're experienced and confident in your skills. Always follow best practices for safety and battery handling. 💬 Got questions or feedback?
