Custom battery galaxy s3
After one of my zerolemon 7000mAh batteries went through the wash, and fried the electronics (cells still worked fine), I decided to combine them and make a 6 cell, 14000mAh battery. I then saw this
project, and decided to beat the storage capacity too. I've wired up some 2A usb ports directly into the battery (these
). They can be used for everything from charging another phone or tablet to powering a usb hub or hard drive (the end goal).
Here's the battery, with the phone
in the picture to show size.
It can power hubs...
Charge my mom's phone (15 times over)...
And technically even charge itself.
