Hey guys, I just got my SPC 2s 8200 lipos in the mail today, and I just finished using them. At first, I didn't notice anything different from running nimh's. A hour and a half later I could see no comparison between them... I love these things so much, I love the run time and having more power for longer! The only thing that sucks is it takes my poor Traxxas EZ Peak Plus 6amp charger over 80 min to charge one... Oh well. Rant over.
