Li-Po question

[mmdooley]

Hi all, I have a "ICE" charger and I charged a SMC 5200 mah 2S1P and it puffed just a little bit. It did not get warm at all, I had a astro blinky on it and it charged and balanced up to 4.10 on each cell. Is it trash or not???? It is nice to be back here, I stopped RCing for about 3 or 4 years. Now I am going to build some of my trucks that I had put away. Like my G-MAXX and FLM MAXX and a couple of stock E-MAXX's. I see some things have changed and some have not. I am happy to see RC Mike's is still going strong.
Thanks
