Max amperage for motor ? batery amp size

[SpeedAssault]

Need some more help on Motor and battery

Is a 95amp max Feigao 2383 motor ok to use with a 160 amp battery ?

Looking at buying Two 5s 1s1p 3200XP 25c and putting in Parallel = 5S 6400 128 amps.
Battery here http://www.neumotors.com/store/page12/page12.html
Or should I get a castle 2200 before I blow the Feigao 7XL ?
any idea what the CC 2200 motor amp is ?

Newb: Trying to learn all this new stuff

thanks

The motor will only draw as much as it needs, gearing and vehicle weight will determine the load.

You can run as big of a battery as you like, only downside will be the weight.

Your 7xl is a hot motor, it will pull over 95 amps, the cc2200 motor is a much better choice. The 7xl is very gearing sensitive, and 5s is too much voltage for the motor, it will most likely suffer from a magnet failure. 7xl on 4s is about as much as I suggest.

Ok Thank you

But I read that the Feigao 7xl 2383 the max amperage was 95 and could do 5S
so , you have seen/read this somewhere ?

I have owned 2 of them, 4s is about all they will handle with out overheating and coming apart.

Where did you read that, on Fine Designs website?

Rated values and real world values/results are rarely the same- the feigao-esque motor may only be rated for a certain ampage or wattage, but half of that is wasted as heat most of the time! Trust in what the old timers say, we've been there and done that many a time, so we know what the reality is vs the specs on paper; Linc himself has owned every BL motor ever made*

*almost at any rate.

Thank you very much for your guidence.
I was hoping to get by with the Fego until I had proper cash for the CC2200

I read about it here http://www.rcuniverse.com/forum/m_6814871/printable.htm

Peak ratings will be alot higher too on less efficient motors- they heat up quicker the harder you push them, compared to better quality motors (9XL vs Medusa 80mm 2000kv- personal experience).

Feigaos do cost ~$60-80, and the Medusa ~$140-150, so I can see the issue there, but its worth waiting a little longer to get a motor that will last years, rather than buying a cheap one that will last a few runs if you dont watch it like a hawk.

If you already have the 7XL, its best to run it with 4s lipo for certain- if you are dead-set on 5s lipo, save up and get the medusa or CCneu 2200kv (or the 1800kv motor thats coming soon- longer and more power, and kv is better suited to 5s lipo).

Great thanks
yea I bought the Fago a few months back for 50.

What's the deal on the Black CC 2200's versus the Green CC 2200's ? .?they are speacial for the e-revo setups or something ?

[_paralyzed_]

blacks are for savages and green is for revos, saame internally

[suicideneil]

Almost:
- the black finned ones come with the BL Erevo
- the black 'pinned' ones come with the FLUX
- the green finned ones come with the MMM esc & motor combo sold seperate to any models.

They are indeed all identical on the inside.

They should make one red with a NOS sticker on it; would automatically gain 10HP and 20-ft-lbs of torque.

As long as the NOS sticker is shiny it will add the power, if it is dull you end up with some sort of weird reg braking effect...the entire time you drive...

I had to learn the hard way about dull stickers on my 89 accord. They just killed the performance. I had trouble beating minivans until I took them off.

[BrianG]

Ah yes, I had forgotten about the sticker finish. They usually all come with a shiny finish these days. The advances on sticker finishes is quite mind-boggling.

[suicideneil]

Aren't red motors faster due to the dopler effect too?

[BrianG]

Could be. Studies are inconclusive on that point...
