As the title states,
Anyone happen to know if a Team Orion 3200 carbon li-po will last a 5min race heat,
with a novak brushless 4.5r. In a TC running on a medium sized outdoor asphelt track running rubbers.

ohh yeah and the car will be weighed up to 1525grams.

you betcha. Keep in mind the 3200 is "useable" where as in NiMh it is "total" capacity. I have ran a 3200 in offroad for 8 minuets with a 6.5 and only put 2200 back into it

i ran the 3200 with a orion 3.5 motor today for 5 minutes (set timer on radio and stopped at 5 minutes) and it took 2590milliamps back in. That was on a TC

thanks guys

I am wondering if the LiPo discharge rate specification is a factor in this type of use.
The 3200 is a 20C battery and if I have understood correctly the max discharge current should not be more than 20 x 3,2 = 64 amps.
The max. current draw of those motors surely is much more but it's transient.

Is it OK to take out of a LiPo peak amperages that much exceed the batterys C-rate?

I know I've seen LiPo specs stating these batteries are capable of short high amperage bursts around 100 amps. I'm suring using a 3.5 BL motor that under the right conditions (speed and traction) that the motor could easily pull a quick burst exceeding the C-rating. The C-Rating is the constant safe amp draw rating, not max/peak amps.
