Carson FS 3K Reflex Wheel PRO 3 LCD 2.4 GHz BEC
I have the version without LCD (Reflex Wheel Pro III) and there I could insert a flat battery in addition to the batteries. I don't know where to order it, but it doesn't seem to be available on Galaxus.
from what i have read you can't keep an extra battery in there
