How much difference between cells is considered bad? My Zippy K 3S packs were 3.41, 3.63, and 3.48 after the last run in the Flux - the other pack was 3.68,3.59,3.68. My Duo seems to bring it back ok, but just wondering if its on its last legs.

That seems fine to me.

As long as they don't go below 3.1 I think they'll be good for a few more charges.

...thanks for this thread fellas...I had some 4900 Rhinos in my basket and just thought i would check here and comments seem to be good...First step to the Lipo Side so I wanted to make sure i was doing SOMETHING right :D Cheers...

MetalMan we should compare notes mae...Sounds like we are almost doing the same things...

E-Sav you weasel :D Is that you? LOVE the MadMax thing you got going on...Makes me want a MadMax Savage :D The only reason i knew it was you was that annoying desk light in the background of all your pictures :D

So do people prefer the Rhino or the Zippy-H cells? I was told that the Zippy-H cells are slightly better quality for the money, is that correct? :D

zippy-H 5000 20-30c or zippy flightmax 5000 30c
 

...The weight is different and the dimensions are different..they got to be different cells. Does anyone really KNOW if the zippyh or zflightmax reliability issues... I have read a lot, but nobody has concrete figures or experience. Some says that the flightmax has more burst current, but suspect it does not last long.... both seem to heat up the same amount if drawing 150A continuously. Dont know the lifetime of the flightmax though.

Lets hear from the guys who really have some. They can tell us what to buy, because I'm in the market for some new lipos.. 3s...x 2 (OR 5s if possible...got ebay 5s cheapies on way as well...)

Lets hear it....

oh.. and HC only has the zippy-H 5000 3s 20-30c avail.... Maybe old stock??

Aye Bit, tis lilredmachine. I'd always wanted something that wouldn't look out of place in Death Race. Har har. Maybe I'll mad max the RB3 I'm gonna build.

Do explain!

...similar batteries...similar parts on our trucks...Thats all...just noting the similarities...Do you have a link to your Savage build?

...E-sav...no i really like that...fond memories of purposely melting and cutting an old black Trans-Am firebird plastic model that i had JUST to make it look like Max's car...

...I like that 'mad max' has now become a verb :D Its sounds better than 'murdering' something...Hmm...might just Madmax the HFX :D

back on topic...It appears the Zippy's, and also to some extent the Rhinos, are made with 10 gauge wire? Particularly the 4500+ packs?

The flightmax packs just came out not to long ago from what I have seen. I dont think you are going to find anyone thats had them for a while. They do look well built and fairly bulky for a 5000mah pack so thats got to be a good sign.

Sure do:

Definitely 10ga. wire. My guess is this is their way of compensating for lesser-quality wire. I mean, their 12ga. probably wouldn't stand up to Deans Wet Noodle (12ga.) wire in terms of current handling, for example.
