Having owned RPi for a while, I realized that it is a portable, powerful and affordable device. But, soon it became evident that the portability becomes limited due to the lack of battery management. So, I looked around and came across few battery management boards that offer such functionality. But the next question was how do you fit that circuit in the currently available cases and how to attach batteries? And the solutions did not appear neat.
It became very clear that there has to be a BETTER SOLUTION. And so BattPi was born.
