I have tested the bigger battery while wearing the prototype. GPS and HRM on always on got to well over 15 hours runtime. That's actually a bit better than I expected from the volume increase of the battery.
The next version will have space for two additional buttons. And somehow more space for the LEDs, since I botched the install by glueing the case shut before the resistors arrived. Those things are tiny... but at least it now works with usable brightness.
Trying to sand the surface of the nylon made it look grey and wouldn't get better by blasting with hot air to melt the surface. So it's probably better to not sand if not planning on painting.
