Is Making Your Own FPV Battery Worth It?

After watching a recent video from ‪@BenToogood‬ I was convinced to try my hand at building my own FPV batteries using 21700 4000mah cells. It was a lot of fun and will definitely be making more. Hope you guys enjoy. I did my best and know that I'm not an expert and don't claim to be so take that for what it's worth. Materials Used Hi-Temp Tape - https://www.amazon.com/dp/B072Z92QZ2?...
