How are Zippy Lipos???
 

How are these two Zippy lipos? I might get the 4s 25c 4000 or twin 4300 20c 2s packs. Or maybe one of each I'm not sure yet because I don't kknow how good they are but they are a steal on price IMO. How do they perform though? All the reviews seem great? Anyone running these? I know thw 2s looks sloppy but hey for only $40 you can't have everything right? I can always put some shrink wrap over it to clean it up a bit... Thanks

i use them as well my friends do. they hold balance very well. 5Ah 5S pack has more power than truerc 8Ah pack. i still need to run them with eagletree on as i am busy with nitro racing, but so far they perform great.

So the 4300 2s packs would be good? Do well in a Revo wired in series for 4s geared for about 40-45?

I use for two months Zippy 3S 5000 mAh in a e-revo with feigao 8XL and MM.
They worked well. Good punch and good to hold capacity.
Now i've sold them to buy Zippy R (more C) 4S 4800.

get the zippy-r 4800 25c's there great and only 80$ there great have just as much punch as my flightpower pack

so the performance is good, but how long have people owned these? will they drop in performance quickly? im not about to waste $80 on a pack only to have it rendered useless in a matter of months.

About 30 discharge in two months for each pack and i see no loss of performance. I charge the packs at 5,5-6A each time. this is my experience.

thanks :) i will buy one then :D

can you also tell me, what is the mimimum voltage you have seen under load with a fresh pack? (my 4s a123 drop down to 10.2v!!) under 102A spikes.

I don't have an istrument to read that value, sorry.

Got a question for ya. :)

On HobbyCity's site they say that the zippy-r 4800 25c is 170mm long (too long to fit in my rusty) But then I saw their pic:

It looks like to me that the wires/shrink stick out from the end. So are the cells really 170mm or is that size including the bulge of the wires/shrink?

hey rusty, i will check when i get home

Thanks a ton. :intello:

Yeah, thats strange, I also want to buy a 3s LiPo for my Rustler VXL, my Nimh batteries are 13,5cm long, and the LiPo's from Zippy 16cm?
I'm thinking about buying this one: http://www.hobbycity.com/hobbycity/s...0C_Lipoly_Pack

I was also interested in the one that you just linked, but I think I'll have to get the rcm carbon chassis first for it to fit.

Just if you don't know, under the ESC the rustler has a little bit of space. If you take that plastic thingy from the chassis the LiPo must fit in. ( Maybe I'm gonna do that )

Sorry for my bad Englisch, Im dutch :lol:

True, but they are still a little too wide, unless you really dremeled your battery tray.

Yes that gives you enough space to fit 7 cell flat packs as well. Friend of mine did it.

I asked this same question a few days ago.

Hope this helps you.

I have a VXL rustler and I had a similar problem when I tried a True RC 4s 5000 pack, I tried dremeling the hell out of the battery compartment and after getting tired of the burning plastic smell, I deceided to install the pack on its side. I drilled holes in the bottom of the battery compartment and used zip ties to secure the pack...I have had no issues with the pack moving and I charge the pack while in the rustler.

what balance tap does the zippy use ??i can't seem to find a plug that will work with the Zippy's ...thanks

XH here is a link to an adapter

thank you azjc for the help...that website you linked me to has a lot of good stuff....thanks for the link

One thing I've noticed with the zippys is that their shrink wrapping is not great. I have blue H packs and the green ones. I had to wrap electrical tape around the green packs to keep the cells from shifting. On the H packs where the wire exit, the shrink wrap eventually cuts into the wire insulation.
I was about to connect one of the H packs to my cordless weedwacker when it shorted rsulting in the following photo. No flames just a ton of smoke. Only 2 cells (6s pack) vented. Overall the performance have been great but I'd recommend re-doing the packaging especially if off-roading or jumping.

I run these packs myself and love them. I'm glad you posted this, I am going to look into insulating the wire to prevent this from occuring. I run the 3s 5000 packs and haven't had any shifting problems as of yet. Its good to note that there were no flames or explosion.



On another note.... Cordless weedwacker???

I've got a craftsman cordless that worked off 2 12vdc lead-acid batts in series (24vdc). Well batts went dead and killed wall charger too. Total to replace was around $55. So instead I killed a $100 6s lipo:oops:. Probably was lucky it wasn't in my maxx though.

btw I think the short occurred at the point were the wires are soldered to cells. But as mentioned before I think the poor wrapping is to blame probably weakening connection after crashes.

I'm reluctant to cut into the packs and see if there may be a reason to worry. The wrap is a little sloppy, but for the money these are great LiPos. I think I will trim the blue wrapping back a touch and drip some rubber cement in there to try and seal up any movement.

cant you guys just shrink wrap them like 2 more times?

I may have one of these and an LBA10 that I will be putting up for sale. I think i have the network cable setup for it too. I put in an order from Vision Hobby for these, then figured out I didnt need them. Cancelled the order/all was fine. Then two months later they show up, and they billed my CC. I was going to send it all back, but my B'in law will need some of it to set up his 989 for his new zippy's.

Sure but I believe his packs shorted inside the shrinkwrap. Where the power leads eject from the cells. So an extra layer of wrap wouldn't help that. It may help his pack from shifting, but a 6s pack is very tall. My 3s doesn't have the shifting problems. I am going to do as mentioned above with some rubber cement to prevent the wires from shifting and possibly shorting.

The size of the 6s pack may indeed be a factor esp. on crashes. Also for on-road use I think they'll be fine since they won't be jostled around as in off-road use. Good idea about the rubber cement. I may do that with my 2nd pack because i also don't feel like cutting into it.

I have a Zippy-H 5000 mAH 5s1p pack and have cycled it about 5 times so far. Not really enough use on it to say for sure but they seem fine. IMO it holes voltage better than my 2x 2s 8k Maxamps setup that I was using before (still use it, but the Zippy is so much more fun) but it doesn't stay balanced as well as any of my Maxamps packs. So far it looks like an excellent battery for the price though. I bought a Hyperion adapter for a Hyperion 0606/0610 charger and hooked it into my oldschool LBA10 balancer and it balances it fine.

Did I have bad luck or what? http://www.aijaa.com/img/b/00772/3081841.jpg
Happened during driving.

4s 5000mah 20C Zippy-H. I had driven ~30 charges with it before this happened. Temperatures been ok and all. Was on 1/8 buggy conversion with mamba monster and 2800kv xl-motor. (maybe 6 charges with this car, then with old cars, inferno and mt2) Charged with balancer and 1C or less.

For those who asked, the 3s 5k Zippy H will not, and can not be made to fit a rustler or Pede. They are way too long, longer than a 7 cell NiMh and a few MM too wide as well. I have two of the 3s 5k packs that I am selling because they don't fit in my buggy or stadium truck. The packs themselves are great and hold up awsome. I had those two 3s packs in my E-Maxx and they never broke a sweat. They performed better than MaxAmps and Venom as well.

A fiend of mine had a similar failure on a Zippy 5s 5000 pack and I had a 5s 4000 pack where one of the main leads was not soldered on properly. I was able to fix it myself on the 4s 5000. This is out of about 8 packs between us. The zippy are for sure great bang for the buck, but with the lower cost comes a lower lever of quality. I expect that they will have a few issues here and there, and in all honesty they haven had any more issues than I have seen with more expensive packs failure wise, but I do think there is room for improvement from an assembly standpoint.

But then again.... Its half the price of the "other" lipos so what do you expect. I'm satisfied with the dollar to performance of them.

So it is probably worth getting them, taking off the shrink and checking all of the connections. I would then wrap them tightly in clear tape to counter cell shifting and then resolder all of the mian leads and balance wires. As cheap as they are I would be happy to get them as loose cells that were matched and just put them together myself...

Has anyone tried purchasing the Zippy R's Hobby City has none is stock would like to get a couple more.

:lol::lol:matched cells:lol::lol:

These are chinese...:tongue:

discontinued:oh::gasp::tongue::no::whip:

HobbyCity are now offering the smaller individual cells so we can hope that they eventually offer the 3k+ cells and prefferibly the 5k cells for us to build packs to fit our needs. We can only hope! :whistle:

Is this true?!?! I was just about to buy some because they were the only lipos that I could afford in numbers that would handle a Neu. :whip::diablo:


EDIT: How would these compare to the Zippy R's ? http://www.hobbycity.com/hobbycity/s...idProduct=7298
