When I first got my mamba max and 7700 I ran Duratrax 4200's and they did ok as long as I was geared 87/15 in my rustler on the street when I went to a 17 tooth I actually popped one of the cells. The hobby shop replaced it under warranty. I got an eagle tree data logger and found out I was pulling 126 amps and pulling the pack down below 5V. For a while I still ran this setup but more closely monitered the temps. I still managed to kill a second pack. After that I got a different motor to tame it down a bit. I still run it from time to time but switched to A123 batteries and just run speed runs with it.

It must be understood that common sense and caution are factors which cant be built into this product.
