Anyone else have some old (6+ years) packs that are still perform strong? Post it here.
BTW, a good pack these days will hold a 20C discharge at ~3.7v/cell (at mid discharge) or how about 3.5V @40C discharge.

Hmm... quite funny I was thinking that my older LiPo's were better than my newer packs somehow. In 2008 I think I bought some Rhino's (at that time they were the high-quality packs at Hobbyking. Is it still like that now?), 1350mAh rated for 30C continious (= about 40A). They've seen lots of 80A+ spikes and the cells reached 2.7V per cell. Now, 4 years later, they're doing nothing in my hobby room with no single cell puffed. And as far as I remember, they always performed awesome during I was abusing them.
I'm very careful with my newer Turnigy packs as I'm afraid one of them will start to burn out of nothing and take out my house as well. So I always put them in a LiPo bag in the garage on a stone floor. But those old and abused Rhino packs lie in my house, without LiPo bag, on a wooden table and I'm very confident nothing will happen with them. It might sound very funny but I'm so scared of my new LiPo's...
