I suspect I have a battery issue. I have a 7 cell, 5000MaH Duratrax NiMh battery that im using in my XL5. It seems to charge fine, but seems weak in the truck. I checked the voltage under load (in the truck full throttle) and im getting just over 5 volts from the pack. This test was after just a couple minutes of using the truck on a flat paved surface. This battery is fairly new and may have as few as 10 charges on it. Im using a Venom Pro Charger, and it is properly set for capacity cut off, and charging at 3 amps. I'd hate to think I have a bad cell already.
