In some sheets the nominal voltage is 3,6 or 3,7 and really it is about 3,8V. This is not a lithium polymer!!!
I bought mine from the german distributor HG-Elektronik. (can be googled) The owner Helmut Gunzert is an expert in batteries or accus, coming to all german expositions with his products. He has no internet-shop, where his products can be ordered. I called him or sent a fax. I guess, his cells have to be shipped from overseas.
I talked to him personally, when I bought my first two cells for my electric sailplane 4 years ago. He told me, that this cells had been developed for and used in electronic tools, originally.
I would not have made a transmitter battery for my 17 years old club-mate in my french club, if this cells were rubbish. Because this young man is gonna mix up the french F3A-scene. Finished the national competition on the 5th place. Among the adults, not talking about the rooky-class!
These cells are not seen so often in our hobby. But they will be my choice as a high-voltage setup for future projects with HV-Servos. In my mind I see a three meter version of my "Raudilio grande".......4 cells...2s+2s soldered parallel to 4100 mAh...
......what I forgot....you can order any configuration, no need for you to do the job.
