I need to get a couple of new T-Rex 450 Battery Packs.

I run the Scorpion 2221-8 with a 13T pinion and a Quark 33A ESC.

I think I will go with Kong Power 2200mAh 25C, but I found some different choices at good prices.

Has anyone used any of these battery packs on their 450 size helis?

+1 on the Zippys http://www.hobbycity.com/hobbycity/...?idProduct=8911

I've had nothing but trouble with the Kongs recently (tossed 3 packs <1 yr old <100 flights)

If you don't know where you are going any road will take you there.

Kong Powers suck really
if you want hard core power then the Kongs are not what you want...

they are heavier and make lessp ower than most packs out there.

If you want the best get the Outrage or SMC's

Jag I respect you but that's just not true at all.

I have Outrage packs and Kong Powers (and SMC 25C/40C on the way). The Kong Power 30C's are so close to the Outrage 30C's it's not worth talking about. (you're talking 4 grams difference also)

The 25C Kong Powers are not as good no, but still better than Zippy packs.

To the OP that sounds like a high power set-up. Go for a combo 30C Kong Power packs or Outrage 30C packs to make the most of it and get the best bang for your cash!

Kong Powers..
I've only tried the older "non puff" ones and the newer 25c ones...the Older "non puff" ones were Boat anchors...lol

I cannot comment on the 30c ones...I guess my blanket statement is not totally true...

Yeah the old style 25C ones are not much cop at all. Funny how they come from the same brand I guess they don't sell the old ones any more. My friend got some of those new KP 25C ones from Readyheli, the power isn't quite there (which is to be expected for a cheap Rookie pack) but the quality of the pack looks good. I didn't weigh them but they seemed pretty good.

I have to agree with Jagz, as the Outrage batterys are truly amazing, and I will never switch, untill I find somthing better. NThey also give a more adjustable set up, as far as Im concerned.

I have 2100 30-40C Zippy H in blue package

At 65% discharged flying, charger always report back that it charged around 2200-2800mah after charge is complete. If I charge at 1C it will report max capacity reached etc. So I charge them as 3000mah.

They last longer then any other 2100mah batteries, they weight slightly heavier then other 2100mah's.

I know charger only give out calculated values of what they put back, either battery don't charge easy to get the voltage charger looking for just mis-labeled.

One of them is more powerful then Kong Power 2200 25c. Other one is so so but a good performer.

I should also state that the Kongs I have problems with are the older No Puffs. I also have several Outrage packs that are by far the best.

However...the OP was looking at discount packs not premium packs; so bang for the buck the Zippy R and Zippy H can not be beat. If you are flying hard 3D and need the punch and performance go with the Outrage if however you are mortal and do sport flying go with the Zippy (I'm trying some Rhinos now that are very promising)

My opinion your milage may vary

If you don't know where you are going any road will take you there.

I picked up another batter pack at the LHS last night, it is a Flightpower 2170 25C. Now I have 2 packs; the Flightpower Evolite v2 2100 20C I picked up at a different LHS last week and the one I got last night.

I want to get a couple more packs. The LHS I was at last night has 20C Zippy Flightmax battery packs for $35 but they were out of stock. The guy working said that these are good packs and he has a hard time keeping them in stock.

Rather than wait for the LHS to get more in stock, I think I will order a couple of these. They are the same battery pack except they are 25C and are only $20 a piece. They are currently out of stock, but I gave them my e-mail address to notify me when they are back in stock.
http://www.hobbycity.com/hobbycity/...?idProduct=7636

Are there any other on-line shops that sell the ZIPPY Flightmax 2200mAh 3S1P 25C for $20?

There are sometimes some available on Ebay, and there are a few other shops that carry them for a considerable upcharge.

The Zippys should be back in stock early May; hold out and jump on a bunch of them then.

I did a lot of surfing for Zippy, Flightmax, and Rhino. It appears that Hobby City is the place to go. Unfortunately they seem to be OUT OF SOTCK on all the popular sizes.

I have heard no comments on:

BlueLipo
http://www.hobbypartz.com/batteries.html

OR

BatteryCole
https://www.batterycole.com/xcart/p...hp?productid=49

I also saw these, which also are said to be Zippys:

http://www.toysonics.com/loong-max-...ttery-pack.html

Has no one tried these packs?

I have my battle wing rebuilt and ready, the T-Rex 450 is all set, and the hyperion foamy plane is cleared for take off. The weather forcast looks good. I can’t wait to do some flying tomorrow morning and a motorcycle cruise in the afternoon.

Well, I got impatient thinking that the ZIPPY Flightmax 2200mAh 3S1P 25C would not be in stock until May. So I ordered the following battery packs.

The first one (Hobby City) is a ZIPPY-H 2100 3S1P 25-35C (USA Warehouse). With shipping I paid $42.
https://www.hobbycity.com/hobbycity...?idProduct=6442

Are the Zippy H’s better than the Flightmax?

My buddy ordered me a pair of these from ebay for $46:

http://cgi.ebay.com/2x-2450mAh-30C-...p3286.m63.l1177

Anybody fly those 2450’s?

Here’s my stable of batteries:

1– Evo Lite 2100 20C
1 – Evo25 2170 25C
2 – WinForce 2450 25C
1 – Zippy H 2100 25C

I currently have the Evo’s and am waiting to take delivery of the others. I like the evo’s real well. I only notice a little more punch from the Evo25 over the Evo-lite, but they are both great.

If any of the cheaper ones come close to the Evo’s I’ll be happy.

I'm shopping for some new 450 packs now myself and just caught these here from another post here on RR.

http://www.aircraft-world.com/

If these pan out they're hard to beat especially if they do go for 4 times the cycles.

I had the same bad experience with the 25C Kongs. What a waste of money
