From the user manual,
" The red LED will blink 3 times if the PCB is overheated."
It is one of the protection features, I suggest not trying to force it to work when a protection feature is causing to not function trying to protect you.
The endura t20s is a non replaceable internal battery.
If it is relatively new try returning it, if not probably time to replace.
Always have backups.
