I have just recently got myself in to the Lipo game. I've been pretty careful, so no problems yet.
I do want to share one thing though. I needed a large pack and my lhs just got a bunch of the new 1500 Kokams in. They were in 2s packs, so I bought 14 of them for a 7s4p pack. Well, I was so excited that I didn't realize that they were wired with really tiny wire. I just got home and started cutting the shrink off of them. They are wired with large servo wire! All the tabs were bent over and hot glued for safety. Knowing how fragile these tabs are, that made it pretty much impossible for me to get the small wire out without breaking them.
This seems pretty irresponsible by the supplier of these packs doesn't it? They even say they're ok to 10 amps. So far I haven't had the wires melt down, but I wont be surprised when they do. I'll be sure to let the person at the hobby store in on this. If Fred Bronk is reading this...
