Just tried out my first SPC lipo. 5600mah,3s,50c. Man, what a battery. I have been missing out. Hope I didn't melt the adaptor area on my traxxas center diff. Quality battery, well put together and not big and bulky. The people at spc are so nice. They emailed to tell me that I had selected the wrong shipping, and it wasn't worth the extra money. They refunded the difference. Customer for life! If you haven't tried one, I suggest you do.
