Weltool T17 Possible Issue

[TheEDCer]

Hey all,

I recently picked up two Weltool lights. One of them is the T17. I had a charged Keypower 18650 3500mAh 3.7v 12.95Wh batter and installed it. The light came on in high, but when I went to the hidden low mode, all of a sudden nothing worked. I then charged up the included INR 18650 3.6v unprotected cell and tried that and still nothing. I also tried to CR 123 and I got a slight flicker but still basically nothing coming on. I have already emailed the seller, but was wondering if the Keypower could have messed up the light?

Thanks

As an update Killzone flashlights said this should not have caused an issue and will get an RMA setup.
