Driver Question

[rookie65]

How well do the Kaidomain/DX Kennan type (AX2002 IC) drivers hold their current levels?
I have a MTb light setup in the making that I have been testing.
With 2x 18650 cells in series feeding these drivers & 2x Cree R2's I get these results.

Started at 1000ma
After 30 minutes 900ma
After 1 hour 800ma
After 1 1/2 hours 710ma
After 2 hours 660ma

Is this normal or should the current levels stay where it started?.

Welcome to CPF, rookie65.

I'm going to close this thread and leave open the identical thread you posted in the Electronics/Batteries section.
