I got a Dynamite Twin Peak charger that seems to charge my mini Revo batteries just fine. My aunt got me a new Venom 5000mAh 7 cell NiMH pack for my Stampede. I plugged it into my charger and it said that it had finished after only 15-20 minutes. I plugged it in and the power was unbelievable and then it the battery was extremely low. I looked on the back and it said for a 5000 mAh pack at 4 amps it should take 90 minutes to charge. What is up with my battery/charger? FYI I took the ESC off of LVD mode before I started driving it.
