Quick and easy

Great app

You can’t enter any values in pack calculations other than watt hours. No place to enter custom capacity of your cells. It gives you result in either 1800mA or 2200mA. That’s it. What’s good a pack calculator if you can not enter actual capacity values of your cells. And in order to see that useless info you have to go and see some stupid ad. Which is what the purpose of this app is probably really about.

This is a simple way to calculate the amount of batteries (18650) and solar panel for your project. Everything is base on your equipment consumption.
