Description

Brushless motor turned monster fan, part 2 done. Installed + tested in one go, the sound takes off on the spot🔥 The spot welder locks the battery in solid — full throttle, spinning like mad, not budging an inch! This isn't a fan, it's a 'turbojet engine' strapped to your body… Take it out in summer — it works better than bringing an AC💨 #MonsterFan #BrushlessMotor #AWithZSpotWelder #UF20BSpotWelder #TechShenanigans

Li-ion safety

DIY lithium packs can catch fire: check cells for shorts before welding, always add a BMS, never skip insulation and fusing on high-current builds.
