Zippy-H 5S 4000mah 25C pack Eagletree run w/ pics
 

Just got my Zippys in today and gave them a quick run around. Very happy so far and these batts pack quite a punch. Just a 5min test, but got 112A (~28C) @ 18V (3.6V/cell.) I also got a pair of zippy-h 4s 2100 mah batts for my CRT.5 with a 12s fiegao. I have a Neu 30C 2500mah pack as well. These batts felt just as powerful. I wanted to do some back to back comparisons, but the 1/8'' motor shaft on the motor snapped... Any know if you can get a replacement 5mm rotor for an S can?:cry: oh well...

The big Zippy back was only $98. Temp was very cool at end of run. 2000+W and not at all stressed. :)

amazing power!!!for for the price:party: i run the zippy-r version 2x 11.1volt 4800mah 25c in my e-revo and wow....these pack are very good in high amps draw


i recommand these lipo pack for sure:mdr:

Awesome, cant beat value and performance like that.

this is what ive been waiting for...


is that huge of voltage drop normal?

i hooked up my wattmeter, and measured 10.2v @ 104.6A with a 42 a123 pack, and i was a bit dissapointed, so will all lipos drop this much? (i.e. how much do premium cells drop?)
thanks,
ryan

Be very careful with those packs. They work great, but I got bad batch a couple of weeks ago. I normally would run with the auto lipo cutoff to 3v per cell. Never had a problem with my more expensive brand packs. I did that with the 5s 4000 Zippy-H and 4s 5000 Zippy H and they got waaay out of balance. It took quite a bit of babying to get them back in balance. One of the 5s 4000 packs did randomly die on me though. I changed the LVC to 3.2/cell and they seem to work fine. Good bang of the buck though. I just ordered two more 5s 4000s.

i own this pack and didnt think that they were this powerfull :D

thanks for the data

Yes, all batteries drop voltage under load. The power and quality of a battery is determined by how much. I assume you have a 4s1p A123 pack? 105A is a 45C discharge..ouch. 2.5V isn't terrible considering, but you need to have a 2P pack for that load.

Here's a enerland based Neu lipo, my 4S 30C 2500mah @32C discharge (~3.1v/cell): This is when I was doing the 60mph passes in my CRT.5.

And here is a A123 pack. A 5s2p pack, 26C @ 2.8v/cell. Remember tho that A123s are lower nominal V, so really a 5S A123 pack is ~=a 4S lipo. Then it equals ~3.5V/cell, which is considered good.

My Neu packs were always miraculously balanced, while I know my TrueRC packs needed balancing frequently. But honestly, for 1/2 the price of a Neu pack (a cheap enerland at that) I can deal with it. My 2yo TrueRC 4S pack is still going strong. We'll see how these zippies hold up :)

Thanks for the data. I'm running 3000 and 4300 2s Zippy-K 20C packs and I'm pretty pleased. It's too bad they discontinued the 2s 4150 Zippy-R packs. Hobbycity seems to be stepping away from higher capacity (>3000mah) 2s for some reason which is too bad. :(

they replaced the "R" 4150 packs with a 4800 series

what does the letters R and K and H mean? is one better than the rest?

Here's a graph of my TrueRC 10C 4S 5Ah pack. This pack suffered a puffing tho as the MM lvc seems to be about useless. IDK how much the puffing effected the pack, but I don't think too much. Clearly the pack doesn't hold V as well, and tended to get hot under the same load.

Lastly my TRC 10C 4S 8AH pack from when it was about a year old. In my REvo this time. Holds V well, but the C is much lower than the Zippy above. I would not try a 200A load on my TRC. Still love this pack tho.

Its where they are from. The H's are high end China packs, the K's are Korean iirc and are aka Loong Max batts. R's are korean too. The other Zippies are cheap budget chinese packs.

H's and K's are good, maybe R's too but IDK.

Thats actually not to bad for 10C cells being pushed to over 20C.

No man, the TRCs are great, but you do need a big mah pack to get good performance out of it. The frickin 8AH pack is 800g+ tho, great for bashing, not so great for racing.

I raced with the 10C 5AH until the Zips came in. It did do well enough, but the pack gets too hot, 120F or so by the end.

They have some 15C 5AH packs in now. In 5S with this 2.5D is should be ok. The price is $142. Not quite the deal the zips are, but then again you don't have to get them from Hong Kong.

thanks for the graphs! fyi i was using a 4s2p pack.... but i guess it was quite a load. would i see a big difference in speed if i ran a 4s zippy pack? (1512 2d with 16/46)
thanks,
ryan

so is hobbycity the only place that sells zippys?

yes it is, zippy is a brand from Hobbycity. Like HXT, Turnigy. The owner alway told that many brand use the same cells as them en sold them 2x the price. I'm pretty sure ualsky use the same source and they are around 50% more expensive.

Honestly HC did improve quit a bit, And there battery are really a good deal. They source directly from factory and you pay for the battery not for the marketing bullshit.

Great result for the Zippy .
I will be using the same pack H 5s 4000mah for heats and my 5s 4350mah PQ for longer finals .

For the price and quality you can't beat the Zippys and i thank Jeff for getting me onto these batteries.

yes thanks for this awesome information...I just ordered two of the
ZIPPY-H 5000mAh 3S1P 20-30C Lipoly Packs.......at 139.50 delivered its a no brainer....i'm hoping these will perform up to par with my just aquired 1515/2.5d in my e-revo..well thats if I ever get my mmm but intell then they should be fine for my twin velinion converted revo

Remember, no overcharging, no over discharging (better play safe and set cut off around 3.1 volts). Balancing on every charge and store them half charged.
Most Digital charger do have a storage mode for Lipo, use it !

when you say set cutoff at 3.1 volts you mean in the esc computer link settings right?

Yeah the esc computer link, the voltage i gave you is per cells so if you plan to run 6S that mean

6 x 3.1 = 18.6 volts

so learn me something here...does that mean with that setting that when you use up 18.6 volts on the batteries which is 22.1 volts, that the system will shut down?

i too ordered the zippy r pack and they work great.got them in 3 days.isnt the zippy r better than the zippy h?i store my packs full charge,is that wrong?

I too am using the R 4800 4s packs. I love them. True mAh readings, and good strong voltage. I noticed a significant difference in switching to these packs from a pair of Polyquest 3700 20C's. Its amazing how much the C's rating plays into the performance of packs.

If you are leaving it for a few weeks-1mo then I don't worry about a full charge. If you are storing them longer it should be @ 50% charge. I know my lipo charger has this setting and it works great. Long term storage @ full charge can damage the batt chemistry.

You start with 22 volts in your battery, as you use it voltage decrease, once you reach the voltage limit (18.6 volts) the power cut off

Just for fun this is a missed movie, My Mamba max cut off right in front of the camera :). (Download might be very slow overseas)

so,which is better,zippy h or zippy r.im thinking of ordering again.thanks

I have both. But I can hardly see a difference quality wise there are both great, performance wise I can't give an accurate and truly "scientific" value.
I think zippy R are better mostly because they use large wire and cells are spaced with a small layer of foam between each which help to reduce heat

hey this was a great post, i learned something new every time i am here

Do they still sell the 2S zippy-R 4000++mAh? cant seem to find them from hobby city

Did you look on different pages , they seem to move the items around to different page numbers when looking for items .

I tried to look via all zippy lipo...zippy-R search keyword and zippy keyword..cant seem to find it...I must be blind or something...later I'll try again

Thanks....

One thing to keep in mind about these packs is that they are wide. I bought 2 of the ZIPPY-H 4000mAh 4S1P 25-35C Lipoly Packs, they say they are 50mm wide. I measure 51.5mm wide. They don't fit any of my battery compartments right now. Kind of a pain. So I will have to modify my cars or sell the packs.

Has anyone tried the Rhino packs?

http://www.hobbycity.com/hobbycity/s...0C_Lipoly_Pack

They say Zippy Battery on the picture on the battery so I was wondering if they are the same as the Zippy packs.

i got the transmitter packs. they are more expensive than the white packs so i didnt bother.

I'm also curious about the Rhino packs. I'm interested in the 4s 3700 pack. I'd run a pair of these in parallel as there seems to be a shrinking market for 2s packs for some reason...

Zippy FTW! I have purchased 3 4s/5000mah/20-30c packs and all have performed flawlessly... and only $84 each.

I also purchased a zippy 3s 2250mah lipo for my transmitter. Totally awesome.

4 Zippy H for me no problem, in fact MMM failed before I could push them
