two blurbs from it

Jason informed me that they assemble every pack they sell right there in that building with the exception of the tiny micro packs. Each and every cell undergoes a series of tests to characterize it, and then it is matched with like cells and assembled into packs. Instead of soldering, the cell tabs are welded together with a very special and expensive welder to prevent damage to the cells from excess heat build-up. I was shown an assembled, but not yet covered pack, and I was impressed with their attention to detail. They are careful to make sure the leads have proper strain relief and that everything is held down tightly to combat failures from vibration

So why are TP lipo packs so expensive? Now that I have talked to Jason, gotten to see TP and have had time to think about it, here is what I believe. First off it's not a simple question to answer, especially when you compare them to brands like those found at HobbyKing. It starts with the cells themselves. TP makes a great effort to only use the best cells they can buy.

Add in the warranty and the fact that they are made here in America, and they just may be worth it. At least that is the conclusion I am coming to
