Rustler VXL Trailer

I was just looking at the graph again. But the LiPo only got 2 times under 9 volt. And I was driving in grass hill up and down. Maybe because of going full throttle up hill got the LiPo beneed 3.0V/cell?




As you see it sometimes get over 80A and the voltage doesn't drop below 3.0V/cell

i dunno!
i'd say it's doin a pretty darn good job!!
yeah so it's pushing the limits...but it weighs what? fark all and i bet it was super cheap too
looks like a heap of fun, the worse thing i did for my rustler is use the 3s 8000m,ah packs, too heavy but cant argue with 1 hour runtime under race conditions (that's how i got 2nd in the MT unlimited 1 hour mains , all the nitro's broke down/ran dry)

What is bad/normal/good for a LiPo? A voltage drop under 3V/cell is bad? Exactly 3V/cell is normal and 3+V/cell is good?
It weights... well... yes, nothing It costed 15 dollar!
And yes it jumps like hell because it's awesome light! And I get a runtime of 15+ minutes. As you see in the graph I was at 13:30 minutes or something and I used 1050mAh of the capacity.

Wow, 1 hour... That's damn long, but I still like my 15+ minutes and super light car :) But for a 1 hour race that's perfect ofcourse!

Going under 3.0V/cell on a Lipo is not good at all. You'll shorten the life of the battery at a minimum. While you may be getting away with less battery, you're certainly not promoting a long lifespan of the battery running the way you are. IMO, it's just not safe to run a battery in application where it will be routinely subjected to currents beyond it's burst rating.


Also, IMO, if the Lipo was an optimum choice for the application, it should not drop consistently below 3.5V/cell until nearing the end of the run.
