Need some battery advise

Hey guys,

I'm getting ready to order a couple of new batteries and I am now rethinking my methods.

I'm doing some parking lot drag racing with trucks. One is an 1/8 scale buggy with a truck body and the other is a Losi 8ight T. The purpose is to cover 132' as quickly as possible.

What I'm thinking about doing is running a Neu 1515 1700kv motor on 6S lipo using a Compro controller and gearing up for speed. What I had originally planned to do was to run a 1515 2700kv motor on 6S, but when I tried that, my esc went up in smoke. I'm still trying to get to the root of why that happened. It may have been a bit much for the controller.

So, my choices are either the 2700 on 5S or the 1700 on 6S. Any thoughts?

My main question is this. What packs do I get? I'm either going to go with Flightpowers or Neu packs. What I need to know is what capacity should I go with to get a good balance between weight and enough runtime to get some good runs without dropping so much voltage that it really affects performance. Right now, I'm really looking at the 3700 evo25 flightpower packs. These should be nice for running the 1515 1700kv motor with some tall gearing.

Any advise is appreciated.
