More details about your batteries please ... brand / size / chemistry, protected or not, button top or flat top ?
Is your BOSS Ti or Al (or something else) ? Threads cleaned and relubricated ?
Does the red secondary ever stay lit (steady) ?
Any flicker ? Any rattle ?
I have tried two types of batteries
efest imr 700mah 10.5A
keepower 1200mah 15A (this is what overready recommended to me)
the batteries are flat top
the light is black anodized aluminum
threads are clean and lubed (light is brand new)
the red secondary does stay lit consistently (I was incorrect before stating that it was only momentary)
no flickering or rattle
The light appears to be cycling through the modes but the LEDs are not working. when going through the modes I get red, nothing, nothing, nothing, red again.
I have re programmed the light now with my phone and my computer. Both times the program has taken. (the dim red led goes out after the video sequence has played). same result.
