how can i have a lipo battery with my teensy for my wearable
I just got my 2 Teensys today and i want to use one in a tiny wearable project for a pet, I'm making a tiny matrix on the collar of a shirt and i would like to add a 3.7v lipo 150mAh battery that i got from AF but, how do i use it with the Teensy when it needs to be charged, can i cut the red and black wire from the battery and connect another red and black to the battery to keep on set with the jst-ph connecter and one set of wire to the Teensy? My wearable piece is 3x4 so it's really small.

If you cut the female end from one of these: http://www.adafruit.com/products/1131
you can solder wire leads to the teensy and you will have a male plug for the battery. That will let you detach the battery for charging.
In general, we do not recommend using LiPo cells in projects for pets. LiPo cells can become very hot, or even catch fire if damaged.

Re: how can i have a lipo battery with my teensy for my wear
Thank You, I will do that. I have those extenders, i ordered them incase i would need them and I'm glad i did. The lipo will not be anywhere that the pet can get too, it will be on the back of his neck inside a piece of fabric, What would cause it to heat up by the way? I purchased a few from Adafruit and i don't want to ever have one overheat. Thanks

The two most common causes of catastrophic LiPo failures are:What would cause it to heat up by the way?
- Physical damage to the battery, usually punctures, abrasions or tears in the outer covering.
Improper charging or over discharging. All of our cells have protection circuits for over charge/discharge. You should also use a charger like our micro-lipo charger to charge at a safe rate for this small cell.
