single cell lipo has a nominal voltage of 3.7V and maximum charged voltage of 4.2V.
14 thumbs up!
these are really nice cells, the voltage when they arrived was 3.83 volts on one cell and 3.84 volts on the other, to get an exact match between cells, use a couple of clothes pins, and clamp the tabs together, positive to positive, and negative to negative and let it sit for 3 or 4 hours before you solder them up, that will give you and exact balance between cells, the tabs are very easy to solder, it took me all of about 10 minutes to put a pack together once I had an exact balance between cells, you want to use around a 30 watt iron, and work fast as to not build up heat, insulate well, I used a combination of hot glue, and double sided foam tape to protect the tabs. make sure you do it right, there's plenty of places through google to find "how to" step by step instructions on making packs out of these little cells,, I bought two of them, I bought them to make a 2 cell pack to use in a GWS Pico Cub.
I stocked up on wire, balancing plugs and JST connectors so I can make more, I will be buying more of these cells.
I've very happy with them and would recommended them only if your comfortable working with Li-Po cells,
there's lots of places on the net to get info on how to assemble a li-po pack, do a google search, and read up on it before you attempt to build one yourself, it's not hard at all, but if you've never built one before, do some reading to educate yourself.
I made labels for my pack on the computer, printed up the label, and stuck it to the pack with
