SRT7 (NOTi) and SRT7GT with RCR123A or NL166 cells

I have an SRT7 and SRT7GT and a slew of Olight RCR123a’s and Nitecore NL177 batteries.

In the GT the low charge indicator flashes FAST indicating low power levels when new fully charged RCR batteries are used but flashes slow indicating it needs a charge when Nitecore NL183’s are used.

My SRT7 with the same batteries does not indicate power issues, so Is this a known issue with the GT?

WB, gino1!

Retire all of those batteries and get some 18650s with 3500mAh and 10 amp CDR .

They’re ALL brand new from Olight and Nitecore, charge fully and none of my other lights have issues with them.
