SkyVolt Has Arrived
 

Just what I've been waiting for...
I just checked FMA's website and they finally posted info on the Kokam High discharge SkyVolt Lipo packs.

You can see them here:SkyVolt

Thanks for the heads up! I've been waiting for these too.Wasn't expecting them for another couple of weeks.

Holy cow those batteries are expensive!?! $255 just for 4s 3200mah... I would never be able to justify a price like that...

Those are suggested retail price which are always a bit inflated. I guess I better start saving up if I'm gonna get some :eek:

I would wait till they a lil cheaper. THose prices wont stay that high forever.

The 6400Mah 2p2s skyvolt packs are comparable in price to the Scorpion and Balance Pro packs, with none of the built in benefits. The charger is abot $45 .00 more than the Scorpion charger.

The product description says, "To charge Skyvolt Packs, disconnect packs from the Module and charge them individually using the Skyvolt 6S Charger". I looked for a manual on the FMA site. Not published there as of today. I was under the impression that these packs offered the same safety and convenience as the Scorpion packs, but at higher capacities. They require seperate charge protection and discharge protection modules, about $60.00 a throw.

Other than voltage availabilty to 22.2v and up to 9600Mah, the biggest benefit is the ability to fast charge. Wow, 22.2v and 9600Mah in twenty minutes, safely. Cha-Ching!:eek:

That would require a MASSIVE power supply! That would mean that you need a power supply capable of 57amps at 12 volts! (factoring in charger efficiency). And on top of that, you need some good wire/connectors!

As other would say, "In the name of science.":L:

The SkyVolt packs are the same technology as the BalancePro packs, with more cells in series. The charger balances the cells during charging and can charge at up to 10A. You need a low-voltage cutoff device (ESC or external device) to protect against over-discharging for both.
Their charge protection module lets you use your own lipo charger to charge the SkyVolt (this is different from BalancePro, since BalancePro requires the BalancePro charger) as well as the SkyVolt-specific charger. The charge protection module will cut off the charge when any cell in the pack reaches 4.2v while charging.
Their discharge protection module is a low-voltage cutoff device made to work with the SkyVolt packs.

Unfortunately, you can't charge any of the 6400 or 9600 packs to 90% in 20 minutes due to the limits of the charger. You have to set the charger to 3C for the 20-minute claim, but it only goes to 10A. You'd need 19A and 28A (approx) for the larger capacity packs to charge in 20 minutes. Either way, it's still nice to charge my BalancePro 2s2p 6400 at 10A. :)

Lastly, the prices on FMA's website aren't suggested retail price; they are actual retail price when purchased from FMA Direct. For example, the 2s2p 6400 BalancePro packs I have cost $285.95 if purchased at FMA Direct, but cost only $199.99 if purchased at Tower. With this in mind, I don't know why anyone would purchase from FMA Direct, but it IS their actual retail price :)

You see now why I am not a moderator.:L:

Hey guys, if I want to get myself a decent lithium polymer batt and a good charger, what brand do you recommend me to buy? I think that thunderpower produces some good lipos, but what about the chargers? is it okay to use the ones that Astroflight makes or do you have other manufacturers that you would want to recommend me to take from beside those that I mentioned?

What about the ones in this thread?

The thunderpower ballancers seem to be pretty good though.. I just bought a 10S lipoly charger, capable of 150watts charge power. (10S with about 4A) i don't know what to expect from it yet..

The prices on the batteries didn't scared me off either.. It's an advice.. Normally (with washing machines etc) you van divide the advise price with 2... Towers is rather cheap with the Kokam/FMA's..

though a prive tag of 550 dollars, and up for one charge makes me wonder if i'll be able to sleep in the same bed with my lovely girl..

Looking for the golden excuse..

Batfish,unfortunately there is one reason to buy from FMA direct and that looks like what i may have to do.
Tower won't ship lipoly via air and FMA will ship internationally.

If anyone knows another FMA dealer that will ship lipoly via air then please share.

The total from FMA comes to over $800 for my order and i still have to add shipping and tax and import duty.could be up to 50% on top.So, if your in europe they really are expensive!

What about rc-monster Mike??

;)

I'll certainly ask the question.
I just assumed Mike didn't sell FMA since others seem to buy them else where.

Well, Mike, can you sell us such things internationally?

I'm sure if there's a demand Mike can get it. I hope so i'm interested in the 7.4V 9600mah packs, imagine bashing all day on one charge

That would be nice. Charge that morning play until the sun goes down. That is one reason I was thinking of lipo. The technology is getting better all the time. As that does the price will come down. I will wait a little longer. I thought about getting two 10500 packs at 18.5 volts. Strap one on each side and go. 21000 mah. That should last a little while. :cool:

And you only need one pack. Now that is something, indeed.

i have a evo and am wondering what would be the best lipo setup? i was looking at the maxamps polyquest 6000s. i currently run a lehner xl3100/warrior 9920 and the magnets just came off the rotor and if it cant be fixed im thinking of getting a new feigao instead. what would be the best setup if i was to get a new motor and what motor would you recommend? i wouldnt mind going up in cell count a little because as of now i am running only 12 cells but 16 is my max because my charge only charges up to 8 cells and i need new batteries anyway. what to get?

For your e-Revo, a Feigao 7XL would be a good motor. If you are looking at going Lipo, how about a 5s 5000mah setup? If you go with 5s, then even 4000mah will be plenty. Your Lehner 3100XL must be pretty stressed in your Revo, so a slower motor would be a better choice.

im not really sure, it was perfectly fine in my e-maxx and about 4 runs in my evo and it gave out. i dont know if it was defective or what but i had only run about 12-15 sets of batteries through it. i really need the 6000s because i need as much runtime as possible because the closest track i know of is about 75 miles away and is outdoors so its gonna be nitro dominated so i would asume its gonna have really long mains. i was also thinking about the 7xl but im not sure how it would perform on 12 cells for temperary. how would it run compared to my xl3100?

The 7xl will have more torque than your 3100xl. I don't know if you will get the run time out of your motor that you want. I currently run a 9xl. I get about 25-30 minutes bashing around. I run 3300 and 3700 gp batteries. I tried the xl 2000 in my emaxx. The 7xl did much better. I just not sure if you going to get the run time your looking for. If you run the lipo 6000 packs. That will bump your run time up. Hope this helps you. I know you a lehner man. Maybe you could get the 1940 or so. Not sure which one is equivalant to 7xl. Good luck.

that 9XL coolhand, how many cells are you using and what it the topspeed your can achieve with it?

I have been running 14-18 cells serum. Not sure on top speed. It does pretty good. I would have to guess in the neigborhood of around the 40+ bracket. Runs cool to. It is like the 7xl I had. Not as fast but just as powerful and run longer. I get about 25-30 minutes on a battery packs. That is with 3700 gp. I like the motor. It runs good even on 14 cells. The hacker people recommend 12-18 cells on there motor. It does nice.

Is it a hacker? i thought a Feigao?

it is a memisis. aka feigao. But hacker is close to design so i sometimes compare the two to help with decission. The more info I have the better. It is better than just guessing.

Well its not close, but identical to the Feigaos in every sense. The only difference might be the quality of both motors.

I doubt..

Well it could be, but the price of the Feigao settles the duel quite well.

Yeah, it makes Hacker or any other brand look weak considering that.

However, the bearings of the Feigao motors need some care or be changed to ceramics.

And even after you bought some good bearings, they still are cheap..!

My bigmaxximum had play on the shaft after about only 2-3 hours of fun..

It's easy to say that you used better bearings..

Did anyone here ever changed the bearings on his Feigao?

My brother had to change out bearings in his fiegao. He knocked the motor apart and that is what we think messed the bearings up. He has put a motor clamp (from mike of course) on it.

Okay, it was not because of the usual wear..

Nope. The end was lopsided. Put extra stress on bearing. I have no problems with any of the one i had. We even ran eighteen cells on that 8l after the bearing replacement. Still going strong today. What a motor.

Whatever.

??? what whatever ???


you state that the bearings need to some care or need to be replaced.. in my opinion that is not the case.. and my 'highend' plettenberg needed his bearings changed too....

I didn't say that the highend motors dont need any maintenance. I too found that my 480-42 motor needed some cleaning after every couple of bashing or racing. There is a difference between things that are made with extreme precision and sold for high prices and things that are made from economic materials and sold for humble prices. I'm not saying that the Feigaos are bad. No. Not at all and they've already proven themselves as highly competitive motors sold for very acceptable prices. There is no need for you to reply in such a wonderous way just because I stated my own concept of the Feigaos and the other motors. I'm not ready to spar at all. HEHE.

well, i simple didn't liked your 'whatever' i need a whole story to make a proper conclusion.. not just a statement.
