Seems it is indeed too large. 65 mm is what I need, so I ordered one.

Cheers

Hi folks. I bought some TR 18650 3.7 V 50000 mAh batteries for this TBeam unit, and it doesn't seem to want to fit.

The holder seems smaller than this battery. Is this true? Did I purchase the wrong battery? I can't find any reference to any manual nor any data on batteries.

Battery length: 67.5 mm

Any insight appreciated. Cheers!
