I am looking at variety of suppliers to fix "flashing battery LED" with NOT EXACT same  brand name of the battery ,  and none of them  specify the physical size of the battery.
I realize I am little paranoid for few $ , but...
Looks as the smallest capacity is 250mAh, no big deal since I am planning NOT to use it without AC power.

I had to go to a vape shop to find the right sized battery. It’s shorter
than the same number sold at Batteries Plus. No built in protection as the
nano has the protection on the board.

Again go to: https://batteryhookup.com/     if you want 18650, 21700
etc... Most have been in standby or lightly used and pennies on the
dollar. I've purchased over 1k bucks worth in the last 5 years.
