Nothing against lab equipment, but the human ear is much more sensitive than the best equipment you can find. Plus it can interpret many more variables at the same time than lab equipment. Tube amps sound warmer, different crossover setting impart a different sound and feel. Various digital to analog converters will produce different sounds. I did high end car audio when I was younger and there is a big difference.

And yes, shit can be built cheaper in china than anywhere else... Why do you think most things have made in china stamped on them...



Oh I didn't even notice your post Linc. You are right, the human brain actually is what is doing the listening... and yes, you can hear differences that a techy in a lab says you are full of shit. There are some things that test equipment is pointless to be used on, and hi-fi audio is naturally one of those things. Not trying to be a braggart, but I can tell the difference between O.F. copper interconnects and silver interconnects, as well as the difference between two different rectifier tubes on the phono-stage preamp. It has a lot to do with the system being very natural, open, and almost free of influence/dampening. This is on a new gen. turn table might I add, which up until 3 years ago, I thought was an inferior medium to store music on.... quite the contrary.


Metallover, you need to have a graph that has notes about each brand's pack, such as FP and Hyperion have much higher cycle life than other brands, and FP, Neu, Hyp can be charged at 5C rates, etc...

FP EONs are Enerland cells, which quickly faded out, replaced by Chinese made EON-X series.

All major pack brands are now using Chinese cells, except PolyQuest of Enerland. Kokam still has some OEM relationships with certain packs but mainly sold in Europe.

zeropointbug 07.28.2009 02:13 AM

Yeah, I mentioned that a few posts back. A123 bought out Enerland and Polyquest is the exclusive Enerland cell packs now.

I think if FP is going to the new Chinese cells, then they must be good. :smile:

I just got (2) 2s Hyperion G3 VX 5500 35C's in. Pack quality and construction is way above Par! It comes with nice thick 10 gauge leads. The pack is super tight. I'll get some Deans soldered on tomorrow and get them a good thrashing with the Summit. I know its not an amp hog but these should wake the beast up.

BL_RV0 07.28.2009 01:46 PM

Sounds good. I think I may have to pick up some of these HP packs.

zeropointbug 07.28.2009 02:16 PM

They are super tight aren't they, that's what I noticed as well compared to my other Enerland HP packs... the G3's feel like a brick.

You won't be disappointed with them that's for sure, but you are going to want to try them in something much more power hungry. :smile: As far as I can see, they are very very close to the performance of the TP 40C packs, based on reports and graphs of a very good reviewer (everydayflyer) on RC-Groups forum, testimonials, and my own experience with them.

nitrostarter 07.29.2009 12:39 PM

Yes they do feel like a brick. Some seriously tight construction and tight heat-shrink. Those cells are not shifting at all.

I'll throw them in my Whiplash 20 hydro boat. I don't think I can get much more power hungry than that.
