An Alkaline AA battery can supply 1.5V with a capacity of 1800–2600 mAh (Haven't found a good way to embed maths equations in the README and have them render in the Project page of the repo, there's http://www.sciweavers.org/free-online-latex-equation-editor and http://latex.codecogs.com/ but they require editing the equation through their website.) This is on a separate line ```math a^2+b^2=c^2 ```
