A battery wizards friend!
"As a life long Electronics Hobbiest, I have studied, bought & used nearly every type of battery configuration out there! My last order included the "new" LiIon AAA 1. 5V rechargeable batteries, but I have a standard, to work with the older Nicole Metal Hydride ••• for a number of my projects. They are a COST EFFECTIVE battery, from which I build battery packs, from 2AAA's up to my 10 battery pack, creating small 12vdc supplies. These are great in powering Arduino's and other home brews, and can be swapped out in an instant. (The Li Ion's AAA's power my Single Cell flashlights, two of them)"
