I know DX light threads have reached level 5 pandemic status, so sorry, but how are people doing this? I have the £50 light with the battery pack, composed of four batteries, which comes with a little velcro holder thing. I couldn't work out how you are supposed to attach it to the frame, as the velcro and buckles seem bizarrely located. Am I stupid?

It fits between top and down tube and the velcro wraps around both tubes.

So the battery is sat in the 'box' shape of the velcro holder, with the exposed battery face against the frame, and the velcro wrapped around the tube?

i put it on the frame but my mate puts it on his stem

fits nice on my stem, wraps up tight

My stem is too short… does that mean i'm not jey?

Not a very good way to attach to my frames so I tyrap the battery to the top tube
