The Lantern Charged for 6 Hours… Then Died Instantly 😳 (Hidden Battery Problem)

This lantern said it was charging for SIX HOURS… Yeah… that was a lie. In this video, I plug in a Farpoint lantern that kind of works while it’s connected to USB—but the second you unplug it? Completely dead. No light. No mercy. So naturally… we open it up. What starts as a simple “maybe it just needs a charge” turns into a full-on battery investigation. I start probing voltages, checking the BMS, and quickly realize the lithium-ion battery pack is basically a zombie—technically there, but not alive. At that point, there’s only one logical move: ⚡ Build a brand new battery pack from scratch. Using a resistance spot welder, nickel strip, and some fresh cells, I rebuild the pack, wire it back in, and bring this thing back from the dead. And yeah… the moment it powers up properly again? Worth it.
