Hey,
I got a Probelm with Connection between my Arduino Mega 2560 and the Lipo Battery Babysitter. I connect as in the Hookup Guide SDL and SDA for the I2C connection. It also need s a Pullup but therefore is a VPU Pin on the Battery Babysitter. I connect this with 3,3V/5V on my Arduino. Finally, I connect an external mini-USB cable for the power supply and a 1000 mAh battery. I use a Basic Sketch from the Suggested library but at the end i got the response that there is no connection between my Arduino and the Battery Babysitter.
I am a Beginner so its possible that i forget something importent.
Thank you for your Help
