I want to supply an Arduino nano with battery, and because I want to be as light as it can be, I cannot use Sealed Lead Acid 6V batteries. I have found this new type of battery:
I am thinking of using 4 of them so I take 6*1.6 = 6.4 volt and a dc-dc-step down converter to go to 5 Volt and supply the Arduino but I do not know if this will work...
Do you know any better way to supply the Arduino nano? Has anyone experience with NiZn batteries? What current they can give (max) per hour?
