TrakPower lipos for Off Road?

[sparrow.2]

I was worried as well at first whether 3200's would be sufficient, but after having run an entire race weekend with a single pack I must say I'm notworried at all anymore. 6 minutes on insanely grippy Astroturf with a 7.5 brushless pulled about 1200-1400mAh out of a pack in my B4.
They are well up to the task and didn't get hotter than 41°C at outside temperatures of 36°C.

I have got rid of all my NiMh's and won't participate in races are not allowed!
