#64 What is the Ideal Battery Technology to Power 3.3V Devices like the ESP8266?

In this video I compare 5 different technologies and show, how they compare if you power 3.3 volt devices like the ESP8266 or the Arduino Pro Mine 3.3 volt.

Technologies used:

Reference: Alkaline non-rechargeable battery
Nickel Cadmium (NiCd)
Nickel Metal Hybrid (NiMH)
Lithium Polymer (LiPo)
Lithium Iron Phosphate (LiFePo4)

I compare their capacities compared to their volume and also how we connect them to our 3.3 volt devices.
