what cell does it use internally? is it a standard 18650 or some weird pouch
pouch cell, like 2600mah or so depending on revision. Not user friendly to swap, you basically have to desolder the tabs

i had one that flashed red and turned out the button itself was stuck halfway pressed. Cleaned around it with isopropyl and it was fine. Seperate issue from the battery entirely
lol "charge it and see" is the universal repair forum advice for anything with a lithium pack
update: left mine on the charger for 6 hours and now its solid red instead of flashing. Progress??
yeah thats actually good. Solid red usually means its registering the battery again. Let it keep going till the light changes color entirely.
