I still have a set of Tanic 10C cells in use form around 8 years ago when 10C were just becoming available, and they were the only 10C cells that were actually capable of 10C, it was before balancing was generally available and they dont have balance leads as such although they do have 3x taps on so you could charge each cell individually up to the same voltage, they have never been balance charged except for at the factory (I assume), I bought them for a 6s1p EDF plane but for the last few years I have used them as 3s2p in a boat, they are old cells although have been in constant usage and have never been stored. While the voltage is lower than modern cells at around 3.1v@10C compared to 3.6v@10C for modern cells, after many years and hundreds of cycles they are still rock solid, still have good capacity, and get no warmer than much more recent and higher C rated cells do @10C.
