flightpower EON X30's.... ?
 

hey guys, i have just discovered for myself the 'EON X 30' series of flightpowers. These things are awesome on paper, has anyone tried them?

They really interested me because of the high charging rates, 5C, that's with the A123's...

They look like they have one of the highest voltage holding capability of high end lipo's out there too, 3.5volts for 30C, and 3.7volts for 15C.

Who sells these, and how much? I might get a set of these; maybe 2 5000mah 3s packs.

You can contact Chuck over at BVM jets and talk to him about the packs. He has run most everything high end and checks and logs all of the battery info. I am sure he has used these, and possibly the 40c tp cells to by now... Really friendly guy, goes by Mac8 on rcgroups.

FP stays with Enerland after Hyperion left. FP's EON are Enerland "V2" cells, reads very nice, wish they are flaw free for long term IR.

okay, cool. So can anyone compare first hand the EON X packs and the TP 40C packs?

Can you charge the TP packs at 5C? Are the cells in the TP packs Enerland V2's as well?

What do you mean by that?

Just some experience that not 100% satisfactory. Could due to my bad luck, but some readings from FE(fast electric) boat forums make me feel not too lonely.

Okay, what cells do the ThunderPower packs use?

They vary.
TP used Enerland and cells from some Chinese manufacturers. Their amazing new ProPower 40C series are clearly not from Korea.

So does anyone even know what cells the TP packs use then? Enerland?

Man oh man, if only these cells were down to the cost of A123 cells, they would be the shiznit for full scale electric cars... in particular, my ultra light electric car concept. Only need 60kg of pack and you have 240kW (320hp), beauty. :yipi:

I am seriously considering either the EON X30 packs or the TP 40C... so any and all info you know is appreciated man. thanks.

Although, for your typical MT, you probably aren't going to tell the difference between the two as far as performance... the only question is, quality?

C rating doesn't matter too much for a full scale car, imagine a wild drive that last only two minutes for 30C discharge and then you have too pull your loved EP car home?

Well of course, but efficiency man, efficiency! You need the voltage to stay nominal, smaller lighter motor can be used, smaller lighter battery can be used (if a hybrid setup is used), you get to a point where battery pack cooling/heating is not important (shedding weight again) and overall well -to -wheels efficiency is higher with higher performance cells. trust me, C rating matters.

That's true, Higher C rated cells have nothing bad except their price(as high as 6 times higher than consumer grade 2C cells) , weight, energy density and cycle life.

Wow. Just found these cells and was going to make a new thread, but I found one..

These aren't a new enerland cell, are they?

3.7V typical voltage per cell under load
Over 3.5V per cell for the majority of a 30C continuous cycle
Unnoticeable degradation of capacity or performance over 100 cycles
15C curve tailored nearly dead-flat with 60C bursts on demand for a completely new precision feel in a high performance model
Exceptionally low internal resistance for cool running
Upto 5C fast charge performance

Any prices on these?

That's what I want to know... I have not kept up on battery development for a few months and just the last couple weeks I have learned of all these new battery tech's... truly impressive performance. All this means to me is that I am no longer an A123 enthusiast for RC... and only RC. A123's are better for everything else (all around).

I was going to get some EON X30's, but couldn't find any sources... then some Turnigy's.... now it's some new hyperion packs (either the 25C or the 35C) for a decent buck too. 5C charging, flat discharge curve(or so they say) and 4x cycle life as well.

Crapamps came out with a flat celled a123 pack, and I expect more companies to follow, so keep your chargers!

First off, who came out with a flat cell A123?

I don't use the A123 chargers, i use a lab quality programmable power supply to charge my packs, very universal and versatile piece of equipment.

Although, I am on the look out for a 0-40volt, 0-20amp unit. For the mean time I am going to probably get a Hyperion 720i.

Where do you get that charger?

MaxCraps makes the pack - http://www.radiocontrolzone.com/show....php?p=2404921
Construction will probably suck along with cell matching.... I'm not sure if a123 is making the cells, probably some off-brand cheapass chinese dirt shack.

How's your EV going?

I got it from 'Mouser Electronics'.

Hmmm 15C charge, now I know for a personal fact that A123's can charge very fast, but stating that it can do it in 15C... BULLSHIT. They would have to have redesigned the whole chemistry for it to be able to do that safely.

I seen A123Systems do a 10C charge (6 mins) on the M1, but at these rates you need to up the charge voltage to actually get the amps they are talking about. Heck, for me to get a 15 min charge(10amps) on a 1p A123 pack, I need to use 3.9v/cell over the standard 3.6v/cell. No if we increase the rate to 10C, that should go up to pretty well 4v/cell, which I know is still safe with those cells, but will lower the cycle life alot. Now, at 15C charge.... well, you get the picture. I call BS, a big pile of burning $HIT.

Who even has the equipment to charge at those rates no doubt!? A standard 15 amp breaker will trip at 1500watts sustained, and thats AT THE WALL. You have to factor in efficiency of the AC/DC power supplies, then the charger, and then the heat created by the cell itself. Enough ranting for me.

Mike actually has the Hyperion G3 packs now, I just bought 2 3s 4200mah/35C packs.

They look like they are pretty much the same thing as the EON X30, only higher C rating (or they could just overrate them), flightpower might just underrate their cells as well... or just different batched cells.

The Hyperions vs. FP:

-Both are a new chemistry
-Both do 5c charging
-Both state 'flattest discharge curve'
-Hyperion says 4x cycle life....FP says unnoticeable degradation of capacity or performance over 100 cycles
-Both have extremely high voltage holding ability

They 'look' on paper like they are the same cells used in both brands... but I thought FP used Enerland? And I thought Hyperion left Enerland?

These new chemistry packs are also alot cheaper than last gens lipos as well.

$96 for 3s 5000mah 25/45C pack

$100 for 3s 4200mah 35/65C pack

I think these aren't enerland, but are the same cells. The chinese cells are getting better and better. I think both packs will be great however, because they both have a good matching process and wouldn't put out a less then top-of-the-line pack.
