From the project

Interfacing the laptop battery with the RaspberryPi

1. Using an I2C isolator to isolate the Raspberry Pi from the lithium battery that is connected to it; if the high-voltage wires come into contact with any GPIO, the Raspberry Pi and everything connected to it will be fried. I will talk about this part more later. You can connect the battery directly to the GPIOs, but this is too dangerous; you are doing this at your own risk.
