Cool new batt for Blade CX!

[Magic Man]

It is an 800 mAh, 20 c made by SMC lightning volts.
Slap battery in, but be careful flying it indoors! Within 2 seconds, you'll be hitting your 9 ft cieling!

[LockMD]

Not if you know how to control it

[Magic Man]

I know, I was just trying to illistrate the difference in power. I may even try to fly it outside this weekend :)

[heyjack8]

hey man about this great new battery where can you find it ..got the link...?

[Magic Man]

I found mine at my local hobby shop, but it seems horizon sells them too.

"smc lightning volts 800 lb" is your search phrase

A true "slide in" hop up

[jksteelehu]

whats the flight time on this battery?

[carlo_the_wonder_frog]

get this instead....http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXRVP5&P=7 cheaper and well proven battery

[LockMD]

Hey Carlo that is the exact battery I have but bought from Australia and it came with the correct connectors. The pic on tower hobbies doesnt look like it will ???

what connectors did yours come with?

[frebou]

There is a version of the FlightPower ones that comes with the connector and the other not... :( Guess which one my LHS had...

2C is better than 20C? Your kidding me right? 2C is a stock batt my friend...

[Magic Man]

whats the flight time on this battery?
Flight time is probably about a minute over stock depending how you use the added power.
The real difference is the hugh power increase.

You read it wrong. The charge rate is approved for 2C. It's an 18C battery, with 28C burst.

Finally got to the specs, your right, but would have to test to see how they work, and 20 c, still makes more power than 18c in my book.

I'm only going by what I have tested

I'll have to look into it either the SMC or FlightPower batteries. I have 3 e-Flite batteries and they are OK, but not great.

I got a new charger and balancer last night and I was cycling the e-Flite batteries. I've been using the charger that came with the CX2 since I got the heli and I found all the packs to be out of balance by .04 - .05 volts. I flew one pack that was charged until it lost hover and put it on the charger. It only took ~490mAh to recharge it. The cool part is it's balanced w/in .01V now.

When I get a chance I'll have to get the FlightPower battery and test it. I believe it's a 12C battery while the e-flite is only an 8C, so it should put out more voltage deeper into the discharge allowing longer flight times. Also, now that I have a better charger/balancer, it will be interesting to see if I get longer flight times with the e-flite batteries. OTOH, it's hard to put a shine on a turd.

So, exactly why is a Blade CX demanding more than 18C, or 14.4 amps?????

I don't believe that any setup is going to require more than about 5 amps. In this case, why would you see a difference between 18C and 20C?

[Paul Hinz]

Magic Man you better go back and look 2C fast charge rate, 18C continuous discharge, and 28C burst discharge. A long way from a stock E-flight battery my friend.

I'll try to answer your question as best I can.

The reason a 20C battery would have more performance than a 10C battery has to do with the internal resistance in the battery affecting the output voltage. The 20C battery has to have lower internal resistance, so it will put out more voltage under the same load. This translates to more performance, even in a CX(2).

Also, as the battery discharges, the internal resistance of the battery effectively goes up and it puts out lower voltage. The higher output battery (lower internal resistance) will not be affected as much and will put out a flatter voltage curve. This means more performance longer into the discharge.

I'm going to look at the SMC and Flighpower batteries for my CX2 just to see how much better they perform over stock. I have learned the stock batteries will perform better if they are balanced and charged on something other than the stock e-flite charger. All the packs were about .05V out of balance and were only taking 490 - 550 mAh to recharge. After charging on the Triton Jr through an Equinox balancer, it took 700+mAh to recharge the packs. Plus the cells were w/in .02V when the charge completed.

[heyjack8]

does any one know why you couldnt use a three cell pack on a cx2 with the same c rating and discharge rate....? it would seem to me a three cell pack would last much longer than a two cell pack to make for longer flight times and not add that much more weight.....but then again i wonder if they even make a three cell pack that would work and not fry your electronics....

Yes we already determined I read the specs wrong the first time

Thanks

[rm25x]

Thanks for the info, going to have the LHS order one.

3 cell pack will not work due to the output voltage increase on the 3S pack.
7.4V 2 cell.
11.1 3 cell.
Take in account the added weight of bigger battery and/or increase in mAh (high mAh heavier the battery). The FlightPower battery is longer and a hair heavier, the length would be a problem unless you mod the chopper. CX2 needs to be as light as possible, those blades push alot of air but not a lot of mass, I think effeicency.

I have flown my cx2 MANY times with the stock battery for the cp pro 3S 11.1V 800MAH

works fine! Although, the higher voltage I'm sure will wear the motors out faster, but it does work.


Edit: I do like the flight power battery 2S is safer, you would think the length would throw off the CG but nope slap her and take off no probs there either.

This is my modified CX2. Extreme extended upper blade shaft, carbon tail boom, under carriage, Flybar modified with weights from Trex. I'm using the Extreme stock 180 motors running on an E-Sky 11.1 volt 1000ma pack. I haven't had any problems with the motors at this voltage. This little heli ROCKS with this setup.

Tower has the FlightPower Evolite 2s 18c battery with the JST connector. See this link FlightPower with JST connector (http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXTCZ5). Pretty good price to.

For those of you using this pack, how do you keep it in the slot? Is the little strip of hook&loop enough?
