Cat Sx Lipo question

[JensK]

Hi guys.
Seriously considering bying a Cat SX. I like the design, seems rigid and one of it most importaint features, its built for Lipo stickpack.

The usage of Lipo stickpacks is the most important feature for me and is one of the reasons I may replace my D4wce for a cat SX.

But...
What is the maximum hight a Lipo-pack can have without gitting in the way for belt & pully?

In pictures shown with Core lipo-pack, witch is 23mm high I belive, it seems like the belt is almoast "resting/touching" the battery pack..

Can someone please clerify this for me

Thanks

Hi Jensk
You're right - the pulleys are close!
There are other threads that will show the issue clearly but any pack whose overall height INCLUDING cell bumps is more than 24.5mm may have difficulties in clearing the pulley flanges.
LRP and Nosram cells have this problem although some ingenuity can resolve this (by spacing the servo outboard slightly so that the whole pack can be moved inboard further - check out the other thread and photos)

Trakpower 4900s and Core RC 5000 are OK - the belt doesn't appear to flex greatly under load and I've not experienced any witness marks that would suggest and rubbing.
I've used TP3600 packs without any issues at all and in a 5min run, I'm only using about 2000mah with a 5.5T which is plenty powerful enough for my liking.

Gotta just add though that the car is definately lush - and well worth considering.

Yup totally agree with the above.

With my TrakPower 4900's it is close to the belt/pulleys but no sign whatsoever of any marks that would suggest it's been rubbing even with my "special" style of driving

So in theory as long as it fits under, you don't need to worry about any flex. So in theory any packs without the bumps should do you fine. (TrakPower ftw though ).

Thanks guy`s
Good answers.
Also, on the Nosram/ LRP packs the battery plug (bullet/corally style) goes through the pack, so you can mount the pack " upside down". If you do it like this the fake "battery slots" would be facing up and therefore you should have more clerance?
Agree??

In theory - but not in practice.
That's exactly what I tried and even upside down, the inner most front cell bump fouls on the pulley flange - unless you can move the whole pack further inboard as was posted elsewhere here...

[JensK]

Ok.
Good to get that cleryfied

Thanks
