# What does it do? Pushes a battery low notification to my phone.

# Why did I write this script? 
#I run a plex server and torrent client from my laptop, in a home office.
#Randomly (usually meal breaks) the laptop goes off cause i'm running it on battery power.
#So this should help remind me to plug in power before it shutsdown.
