I just want to know, how long the battery lasts...

I printed this, but led that i bought is too long to fit. so I designed a new frame that fits the led that I bought.

Btw. the Mount Arm is pretty weak if printed in original position. especially if you have poor layer adhesion. it's much stronger if you turn it to the horizontal position is slicer.

Way brighter than my '400' lumen bike light.

Have pitched the angle down a bit more to not dazzle oncoming traffic and it still lights enough of the path ahead brightly enough to avoid obstacles and while also providing a softer light to the sides.

One down side is it lights the front mud guard up a lot. Was thinking of cutting it down a bit.

I love the retro design. (Must print in silver pla)

Why not use a 3S lipo at 11.1V?

Cheers, I think it needs a shade or 'eyelid' or whatever the thing is called. I'll see if I can figure out how to do that in onshape.

I used the 2S lipo because that is what I had spare!

Lipo batteries are normally damaged if discharged below 3.2v per cell, and potentially burn when recharged. A Lipo saver in line can protect your battery from over discharging.

Yeah, some protection would be good, but as it stands, the LEDs dim past the point of being useful before the voltage drops that low with the Lipo I'm using.
