My bike light stopped charging this winter. I was hoping it was a battery issue and that I could replace it with one of the many batteries I’ve scrapped from street vapes, but the repair was easier than that. I published the repair on iFixit, enjoy, and make sure you have some dielectric silicone compound handy. I’m hoping my light continues working until the battery fails. Expect updates here.

** Update 4-7-2025 **
The repair is holding true. The light seems to be working as if it were brand new. Prior to its repair, the seemingly diminished capacity of the battery forced me to use it in camera-only mode and with the light’s LED extinguished. After this repair, I am happy to report I am once again using the light’s LED and camera simultaneously, functionality is fully restored!
