7-cell vs. 2s lipoly

[dirt101]

The power difference is INSANE. I went from a gp3300 7 cell, to a 2 cell lipo and I was amazed. It was definatly the best thing I have ever done, but im warning you once you go lipo you never go back.

I aggree with this 100%.

SOOOOOOOOO much more punch from a battery that weighs alot less mah for mah.

This is because even the BEST Nimh battery is VERY limited on maximum discharge. About the best you can hope for is maybe 45 amps. At this rate, the Nimh cells get really hot. Cheaper Nimh cells get so hot, they melt things. LOL

Even a cheap 2S Lipo will outperform the best Nimh packs money can buy.

It's an entirely different chemistry with alot of advantages.

Lipo packs have came down alot in price over the past few years too.

Go Lipo, you'll never go back. But first, research the proper care and charging of them. Always be safe.

I agree too. But don't ask this question over at the Trx forums. I got into an argument with someone saying that NiMHs can be just as good. His "proof" was a clearly biased (and obviously incorrect) graph showing NiMHs doing better than some FP (IIRC) cells of equal capacity. Whatever . He rambled on how he backs up his statement with "facts", but I guess we can all disregard the numerous graphs out there showing otherwise, in favor of his one questionable graph.

This is one of the reasons why experienced users dont post on the TRX forums let alone search them... If he had said that to me and "claimed" he had proof I would have exploded in laughter and probably same some things that would get me banned. Course it really doesnt take much on the TRX forums...

Haha ill second that. i ran those same batteries and went to 2s 4900mah rhino's with my emaxx and theres such a huge difference. ill never own a nimh again.
