I'm using the spc 6500 65c batteries for my sc10 4x4. I use a tekin pro 4 hd 4300 Kv and a tekin rx8 Gen 2. With no current limit. After about 2 months my battery is still in 100% brand new condition. The resistance is at about 0.5 mohm. The case has not deformed and the battery has never got above 110. I HIGHLY recommend spc lipos. They are a great price too.
