What if I use same 9V battery as yours and not using 1 ohm resistor, is it ok or LED will get destroyed?

[redfox05]

is it a good idea to be fixing that LED to the battery, will this not heat up the battery and destroy it? Could be dangerous. Should attach this to a heatsink instead.

Hi,
nice project! Wanted to attempt this project, but I was curious:
1) How did you manage to waterproof it? From what I see, the terminals are still exposed, and might cause a short-circuit.
2) How long would it last on a single charge?
