Ultimate DIY 60,000mAh Power Bank (222Wh)

A powerful DIY power bank that can output more than 200w for only $95 in raw materials, while all other commercial solutions cost 300+ dollars. Highly portable and features DC 5-55V, AC 110V output, which can power virtually anything below 200W.

Disclaimer: I am not an electrician. Attempt this project at your OWN risk. Lipo battery can easily catch fire and explode if mishandled. This project requires a more than basic understanding of electronics to complete.

Also, I'm aware that the battery bank in this video is technically 20,000mah @ 11.1v. However, it is still the exact same amount of power as 60,000mah @ 3.7V; I used 60,000 mah to better express the sense of capacity to the average viewer. (Since nearly all commercial power banks measure mAh based on 3.7v)
