Solarforce P1 internal dimension

[NYCT]

Would anyone be so kind as to tell me if the Solarforce P1 will fit a Panasonic NCR 18650 3400 mAh? Much appreciated, if it does fit is it snug or tight? Many thanks

Your question piqued my curiosity. I have five Solarforce P1 hosts, and my caliper measurements of each show an internal bore diameter of 19 mm, without any variation measurable by digital caliper.

Also, every kind of 18650 cell I have (including Panasonic) slides into each tube easily, without friction or subsequent battery rattle.

For what it's worth...

Thank you kindly Dave, your answer has helped me greatly, I really appreciate you going through the trouble of actually measuring the ID! I shall be purchasing a P1 safe in the knowledge my chosen cells will fit, all the best!
