Zippy battery cell quality
 

Is there a difference in cells between these 2 as far as quality goes.....just curious that's all. I know that 1 is rated at a higher c rating. Is the cell quality the same?

The C rating is usually (read: shoud be) a reflection of the cell quality. But since there is zero standard for these C ratings, theyre basically useless.

That's said, Ive tried every cheap cell money can buy (ie no enerland cells haha) except for those new 'flightmax' packs. So far the rhinos are the best quality by a long way. Next on my list is those 25C flightmax's.

I have 2 Zippy's already, I noticed the newer Flightmax line and wondered if they were the same as the regular cells. People have been having great success w/the reg. cells and I was hoping that the same was true for the newer line

I just got 2 of the flightmaxxs of the 2nd link you posted. I havn't had a chance to use them yet, but they look very good. I know its on the inside what counts, but they did arrive in VERY good balance:

B1: 3.88,3.88,3.88

B2: 3.88,3.89,3.89


I say get the flightmaxes. :yes:

We just ran 2 X 3S Flightmax's on my buddy's E-revo MMM.....Very nice battery indeed.

Are u referring to the 5000mah Flighmax's ? They are 50mm wide & they fit nicely in the E-REVO battery compartment ?

Yes the 5000's and yes they do fit.

Good info thanks.

Thanks all for your responses....

I run a couple of the Zippy-H 5000 20-30c 3s packs in a VXL Slash geared 29/76. Never had an issue with them running hot, showing any sign of stress or going out of balance. Even at cut off the cells are usually within 0.01-0.02 of each other in terms of voltage, and they take a good 4900 back. Good power and runtime too, even with the silly gearing and heavier Slash.

Considering that they set me back the price of a couple of decent 6 cell nimh packs I am well impressed with them.

I was checking out these packs too. On the Flightmax 30c. The dimensions are all different on some of the packs. The 4s is 140x48x33mm and the 3s is 143x50x24mm.
I wanted to put the 4s in a rustler. I wonder if it would fit?

That info on HC isn't the best, sometimes the measurements are out by a couple mm.

My brother had some zippy-h's both which had a cell that would always discharge more quickly than the others. he ran 6s in a savage conversion, and packs got a bit of warmth to them. still going strong though. The rhinos own though haha.

Nothing but good luck with the Rhino packs here. My buggy has been running a 4s 4900mah Rhino pack for some time now without any issues. A couple weeks ago I got 2x Rhino 4s 3700mah 20C packs to run 8s 3700mah in my extended Savage with a Medusa 36-80-1100. So far so good! On the way I have 2x Rhino 6s 3700mah 20C to run in parallel in my XLB (6s 7400mah!). I also run a Zippy-H 5s 5000mah in my truggy with a Medusa 36-60-1600. Can't beat it for the price!

Thanks For you input....I will be needing 3 or 4 5s packs in a month or so for my revo conversion.

Looks like it would fit. The Zippy H are some of the biggest cells in terms of physical size and therefore some of the biggest packs around. My 3s just fits into my Slash without an extension kit for height and they are listed at 160 x 51 x 24mm. So provided those dimensions are correct within a couple of mm you should be able to drop that 4s pack into a Rustler as long as you can get or make a hold down for it.

there is a lot of good feedback on the zippy h packs how are the flightmax packs?

Quite a few people have purchased them here and I am sure we will see some input soon. I know tdc57 has some of the 5000 30c packs and he will run them this weekend at the socal bash.

The zippy-h's are ok, the packs I have all have a cell or two that discharge significantly quicker than the others, it's still close enough that the packs havent been damaged over many cycles though. My rhinos (4 3s packs in total) all keep their balance spot on cycle after cycle. Some data on any of the 20/25/30c flighmax's would be good.

I'm also very interested in the 30c Flightmaxes. A 4s pack would go nicely into the Slash with an MMM and a Medusa.

4s might be a bit much in a slash:whistle::rofl:

Lol I nearly wrote the same thing :p I think 2s and a mamba max combo would be plenty.

Slash + 4S = lots of fun!

It's not a Flightmax pack, but it's 4S nonetheless.

Damn straight. Overpowered 2wd is where it's at. Besides, Teh madmax Slash is no normal slash!

Har Har.

I just got my 25C 5000mah 3S flightmax lipo with a full charge and tried it out in my emaxx. I recorded a 120A peak at 10.13V. Thats actually not a bad voltage for a burst current which was me full throttle. Oh ya my truerc pack 8000mah 15C was at around 6.4V for the 120A spike. My Truerc pack has outperformed many other lipos I have owned. I would say these flightmax packs are legit. The volt drop per cell is less in the 5000mah pack than the paralleled 4000mah cells that the 8000mah pack is running. So about .3V per cell drop vs .5V per cell drop in the truerc pack. I'm sure these numbers will drop a bunch after the cells have been discharged a bit, but its still some good numbers for the flightmax.

Has anyone tried the 3500mah 4S 30C packs?

According to the dimensions posted, they should fit the E Revo - E maxx compartments for a nice parallel setup.

Using 2 packs, that would make for a high discharge setup at 7000mah.:yes:

The thing that worries me, often they are a little bigger than the sizes they list.

Anyone know?

If they do fit, your arm would get tired before your batts. run out:yipi: In other words...PERFECT SET UP!

I just received a pair of the Vislera Brand that are identical to the Zippy 3500mah, but they are bigger than advertised.

This is because they used sponge tape between the cells. So the packs are thicker.

I'm tempted to take them apart and remove that.

They will fit, but just barely. It's quite a job to get the doors shut. LOL

The good thing is, they don't break a sweat. They don't even get warm really. I have a feeling I'm not pushing them at all.

Has anyone tried the Chargery hardcase packs yet?

I got some prices from them & they aren't that bad considering they're a hardcase & ROAR approved.

That's exactly as Jason Wang sent them.

PM me your email & I'll forward you his email.

Maybe he chargery's more to the US market. :lol:

On another note, these Medusa 70 & 80mm motors are damned good value!

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.
