I bought a rooster crawler esc and an 8 cell split pack. I have now become aware that the rooster is only rated for 6 or 7 1500mah cells.

So how bad would it be to run the 8? Should I just send it back and get a 7 cell?

You should be ok, just keep an eye on the heat and know that your BEC will be lower than rated spec.

Crawlchevy · 04-09-2008, 05:38 PM

How hot is too hot?

JohnRobHolmes · 04-09-2008, 06:03 PM

Keep the heat sink under 140f, or 160f if you want to push it a bit. It should actually handle around 200f.

Crawlchevy · 04-09-2008, 09:16 PM

alright cool. I hope it will not get hot.

did you take the time to confirm that with the specs listed on the esc? Novak recommends a 6cell 2s lipo max... I have seen people running 7 and even 8 cell, but not 12.

read a little bit, it may actually save you some time and money.

what about the super rooster?
and do you think that i can run a novak super duty with the motor conections combined and with 2 6 cell batery packs? or would i just over load my single 55t?

Biscuit · 04-14-2008, 09:23 PM

I looked in the book that came with mine and it plainly states that it is rated for a 7 cell pack max.

Good thread b/c I had the very same question. I got the Rooster/Novak 55T motor combo in my Scorpion and am currently running a 6 cell saddle pack. I noticed the ratings said 7 cell limit but I figured an 8 cell would be ok. Plus I'm running the optional Novak cooling fan on it. Does anyone know how much the fan actually cools the esc down? I plan on get a BEC for my set up as well.

mudboger07 · 04-14-2008, 11:21 PM

crawlchevy, if it works on 8 cells let me know, id like to add another cell if it does.

Crawlchevy · 04-16-2008, 12:07 PM

Sorry man, I returned the 8 cell for a 7 cell this week I figured that I didnt want to risk it. I have now gotten my axial kit together, just need to make some plates to add to the side plates so I can get 2 1/4 ride height with my droop shocks. These things are just like the real deal, always changing something.

For reference, I have been running a 3 cell LiPo on a Rooster 12T successfully for several months in my very heavy scaler, no problems at all.

I was told that the internal BEC is the main limiting factor in battery restrictions for esc's, so I added a CC BEC and all has been great. Running a 3 cell, I also added an external LiPo cut-off.

This is also what I have heard. They say as long as you run a external BEC it can handle the extra cells ok.

Oh Man..... :(

Try running a BEC or reciver pack, pull the red wire from the ESC servo plug first. This should help prevent it from shutting down, or over heating.
