My son got an 1/10 GRANITE 4X4 V3 MEGA 550 Brushed Monster Truck. It came with the Nimh battery and charger and after maybe 2 runs with it the battery stopped charging. It took hours to charge anyways so I decided to go ahead and upgrade to the Li-Po battery 2s with the Powerstage Bundle. I moved the pins so the truck would take the Li-Po battery and charged said battery. Ran the truck one time with the Li-Po battery and now this battery wont charge. I've put in two help tickets at Horizon Hobby website without any response one for the Nimh issue and another for the Li-Po issue. Any ideas what is causing this issue? Only had the car for about 2 weeks. Spent most of our time waiting on batteries in the mail.
