Sofirn TK70 issue

EDIT: seems it’s been fixed on new batches.

I just received 2 out of 3 TK70’s and they have a big problem that I’m surprised passed testing.

The springs are too short or the tube is too long. 1pc flickers when shaking and the 2nd completely turns off and on. Both batteries are shaking loudly at both ends

The SP70 springs are quite a bit longer

I’m also using Sofirn’s HD 26650 button top so it’s not an issue of flat top’s poor contact.

wow thats poor quality control from Sofirn. I noticed the Sofirn batteries in mySp 70 rattle around a little as the body of the light is a larger width . The length ia fine. I wrapped a piece of masking tape on each end of the 2650 cells and no more rattle. I would send the two lights back if possible. Best of luck
