Zippy vs Enerland - performance > price

[jnev]

At the moment I am running Enerland cell based packs in both my 8ight (Hyperion 4s 5350mah) and CRT.5 (Flightpower 4s 4270mah). However, as my 8ight-T conversion is coming to an end, I need to order the final pieces for it. I have a Neu 1515/1.5y (1500KV) for it that I will run on 6s.

Now my question is, is it worth spending about $260 on a Hyperion 6s 5350mah pack when I can get two Zippy-R 6s 4800mah for $118 each?

Basically, what I am asking is, does the price of the Zippy pack out weigh the higher performance of the Enerland cell based pack... in this case the Hyperion pack? Because I am running 6s, the amp draw shouldn't be as high as a 4s set up, so would I be safe in running the Zippy pack? I haven't had the greatest experience with cheap packs, which is why I am a little hesitant in getting this pack. If I go with the Hyperion pack, I know I will get a quality pack that lasts and gives great power.

Let me know what you guys think.

Thanks!

the only question for me is, how will they last? in saying that, id rather spend 75 bucks on a 4s pack, get 20 mins of track time and swap another one in and have another 20. the performance is more than adequete, but having never owned a enderland based pack i cant really help sorry.

but u cant beat value for money. my only concern is that the pack was at 110-115F after 15 minutes in 125F track temps. is this too hot for the poor lipo?


also i noticed that the cells in my pack slide around a bit. i thought it was puffing on its first track outing but the cells were all rock hard and nothing had expanded. the middle 2 cells had slid forward 2mm and were up against the end shrink pack. i slide them back and didnt happen again, but if this is a continuing problem ill just leave them at the front where they cant easily move.

hope this helps,
ryan

Id do zippys, For the price on enerland, it isnt worth it

If you have the cash, go for Flight power or what ever, but id rather have a few of the cheaper packs, there still better the max amps and what not lol

Why not neu packs?

You get what you pay for. Enerland are the best. (Neu's are built with Enerland cells) You can skimp and get inexpensive packs which have questionable runtime and limited lifespan or you can spend a few bucks more and have one less thing to worry about.

+1 on the neuenergy lipo packs....or you can get the 25c elite lipos which have been great with my muggy conversion....cheapbatterypacks.com

i am running two 5s zippy-r's on my 12 pound UE emaxx in parallel....i am have Plettenberg BigMaxximum and Schulze esc,they are very powerful and give me a full hour of run time!...they charge up to 21 volts and run very cool!....for $99 each they kick ass!

[tc3_racer_001]

i think they are good enough. they are cheap enough not to be too worried about exact specs but perform high enough to satisfy us, im sure the higher priced neu packs will be better but for me, the zippies do it. on the other hand, im looking for some smaller 4s packs (true 25 or 30C) so i can reduce weight. any ideas? (6 minute races.)

Been racing a pair of the zippy 5s 5000 packs in my truggy all season. Also for long mains (20+ minute) in the buggy. I also have a pair of the 5s 4000mah zippys that I run the qualifiers with. At this point I doubt I will be buying enerland ever again. Just not enough difference for more than double the price IMO. I have many (I mean many) Enerland packs that I use regularly also. Enough to show up to the track with them all charged and run pre-race practice in both buggy and truggy race all 3 heats in both classes and the mains without ever recharging a single battery untill I gt home. Plus a couple extra just in case I get a bump up or something.



I like the enerland and they are certainly higher quality in terms of construction, but cant see a real world difference in the way they drive. Ive killed a couple Maxamps packs in my day also so I do know what crappy packs are too.

Just make sure you balance them and they will be just fine.


EDIT: One note... Now that I think about it, I did have one issue with one of the 5s 4000 packs. The first time I ran it it just went dead after about 1 munte of running. No voltage at all on the main lead, but the balance leads all shoed perfect voltage. SO I opened it utp and found that the pack must have been soldered on a monday morning or a friday afternoon, cuz the main lead was soldered on the very very edge of the solder tab and it was just barley on there so it brok off the first time I used it. No big deal. 2 minutes later I soldered it back on and have had not trouble since with it.

Another note. The charger I use is the FMA Cellpro 10S and while it charges it also measures the internal resistance of the cells. I get around 20% lower internal resistance reading from the zippy packs than I do with my enerland packs and the temps the Zippy come off the track at are also easily 10F degrees lower also. Just my observations.

Internal resistance is usually a measure of the cell quality. While I'm sure the measurements the charger takes are not 100% accurate, they should be a good relative measurement.

HC say that the zippy-r's use korean cells but wouldn't disclose who from (apparently part of a privacy agreement), whatever that means. I know enerland and kokam are two reputable lipo cells manufacturers in korea, and know of none others. I've also read about plenty of problems with zippy-r packs. That said, I have a heap of zippy-h packs which go alright for cheapo's, and I've also read about plenty of problems with the mamba monster but am yet to experience any :D

I appreciate the replies guys. I think I will go with the Zippy-R 4800 6s pack. It is supposed to be better than the 5000 pack, but not as good as the 4000 pack, but I need the extra run time. I can also get two of these the price of one Enerland cell pack.

Does anyone know where I can get an adapter from the JST-XH balancer tap to a Hyperion or Flightpower tap?

Thanks again guys!

Edit: Two more replies... thats great to hear jhautz that the temps of them are so low. Sammus, you have heard of problem with the Zippy-R packs? What kind of problems exactly? You think it would be better to go with the 5000 or 4000 packs instead? I also have two perfectly working MMM ESC's.

I hope these aren't digs at the people who have killed multiple MMMs. Because if they are SILENCE!!! I Kill you

+1 on the zippys. They perform great for the money. Like JHautz said, I am going to have a hard time buying another one of the name brand packs. I race my buggy with the Zippy 5s 4000 & 5000 packs and have a couple of 4s 5000 packs. Plenty of power and I can't really tell the difference between the zippys and the enerland based packs I have.

The zippy's aren't built as well as I had a couple of bad solder joints that could be easily fixed and also had one pack die on me randomly but given that they are less than half the cost of an enerland pack, I will take that risk. With that said, Hobbycity does sell the polyquest packs pretty cheap too. However, the value of the zippy relative to the performance can't be beat.

By the way, the Zippy-H 5s 4000 pack is really a 4350 pack. i have noticed some of their < than 5000 mah packs charge up a lot higher than their rated spec.

i have my cutoff set to 3.4v/ cell and when i recharged the 4800 i put 4820 (ish) into it.. so i wonder how much these could take if i had my cutoff set at 3.0? id say 5000 would be close.
