Step 1: Putting It Together
NB (lipo batteries are dangerous if not used properly!!!!)
NB (never over charge or discharge a lipo, lowest voltage must never go below 3v and never over 4.2v)
NB (use a lipo charger used for RC cars, planes etc)
I had a small, well I had two, lipo batteries from an old mini RC car, or helicopter, well some device like that, it had been in my component draws for awhile.
It was rated at 250mah and 3.7v, this is perfect for running a 3w led for about 20min.
I made a small PC board with a switch and a connector, the board was cut to the size of the battery.
The switch was used to turn the light on and then when turned off connect the connector for charging to battery.
I took the little connector from an old electronics board that I had lying around that I use to strip components from when needed.
I kept this all simple as you want to keep this very light so not to affect your flying time.
One I had soldered all the joints and cut the tracks, I used my belt sander to sand the solder joints smooth and flat so that there was no chance of a spike piecing the lipo battery, this also shaved off a few grams of extra weight not wanted.
I used some copper wire to hold the LED to the board so that I could move it in the position that I wanted.
I wound the copper wire around the LED lens and then twisted the two pieces together in a tight twist all the way to the full length of wire that I was using.
I then soldered this onto the board, make sure that you are not shorting anything out when you connect this to the strip board.
I then used some double sided tape and glue to glue the board onto the battery, making sure there could be no harm to the battery.
Step 2: Mounting the Light
Step 3: Finish
When I get the change I will upload a YouTube video of some light flying

LIPO BATTERIES MUST BE USED CORRECTLY!!!!
