I just took my Rustler Xl5 to run on a dirt track. The first battery I used was a Duratrax 5000 mah NiMH Battery which lasted pretty much the whole 25 minutes, then I waited about 15 min for the motor to cool down.
After I put on the traxxas 3000 mah battery and that was when I had very little run time A Lot less than usual when I use this battery. I bought the rustler like 2 weeks ago and that traxxas battery it came with would
work fine the other times I'd use it. Just today it seem to die out really fast, after using the Duratrax battery and waiting 15 min. I would just like to know what can be the problem? I'm using a dynamite megapeak charger by the way. I charge on 4 amps.
