  • Great bang for the buck power.
Lots of juice I got about 25 minutes of continuous bashing before it started to slow down.

  • Good replacement for stock battery
Mine held a charge and worked fine. First charge it was really hot, but after that first charge it was normal. Seems to be working as expected. Good replacement to the stock battery that came in my Traxxas Slash 2WD.

  • Works as advertised.
If your not ready or can afford expensive lipo batteries this is for you. Quality products made by Traxxas is always the way to go. I've had problems with other non Traxxas batteries.
