Baby Tron Costume

Step 7 Powering the costume

I purchased two lithium polymer batteries to power the costume.  When I placed the order, I wasn't sure how quickly it would drain the battery and I wanted to have a spare battery.  One of the batteries is a 2000 MaH and the other is a 1100 MaH.  I decided to use the 1100 MaH battery.  After several tests, I found that it lasted in excess of 2 hours (intermittent, but frequent use).  

Just like the El-Wire and the inverters, you'll need to solder a JST connector onto it.  Its quite simple to do, and you should be a pro by now.

The other side to the equation is that you need to be able to charge the battery.  I decided to use the li-poly charger from Sparkfun, but not mount it in the device.  Since this was a one time use costume, I didn't plan on recharging it frequently.  If you already have a way to charge li-poly batteries, you don't need to purchase the one from the materials page.
