I have to say, having switched over from Trinity, I really like these SMC LiPo's. And to be honest, the extra price I paid for the Trinity stuff, might have been just because it was labeled "platinum" or "Ex-Tech" etc. I am waiting for some more of the higher mAh batteries to come in so I may order more. I think all in all, they are a great investment, and with a price that seems fair and lets me purchase two packs from SMC vs. 1 pack from Trinity. Just hoping the Shorty 4S comes in to give it a try in my buggy.
