Yeah I'm really glad you did all the writing, cause I would not have probably stepped for a long time into the wonderful world of Li-Ion, if I had not read your project instructions So thanks again!
Yes your new battery has impressive specs, where did you get your cells from? In the beginning I bought some single cells from a user called "akkuzelle" at eBay, but some of the cells were in poor condition and I think I destroyed the rest by overheating them with a soldering iron
But then I learned my lesson and bought some unused BP-941 batteries, disassembled them and soldered the cells into packs of 5 really carefully. Holding the soldering iron on a cell for only less than a second, and cooling the cell right after with a cloth soaked in alcohol.
The current battery that I'm using has 1,8Ah cells. The BP-941 batteries that I used, I got from Akku-International. According to the given info about the batteries they should've had at least 2Ah cells, but I guess I was not so lucky . And the batteries were actually something like 24 euros a piece when I bought them, so not a good deal. I did try to complain about the batteries, but surprisingly this seller's english got a lot worse when some problems appeared . But anyway with the 1,8Ah cells there still a lot of capacity, and as you said, a weight of only about 1kg.
So thanks again!
