I charged the Traxxas 11.1v 5000mah batteries with the Traxxas 2-cell/3-cell Lipo Balance Charger Friday night and I drove the truck 20-30 minutes Saturday and Today and they still haven't shut down. How long will these batteries go before the Low Voltage Detector shuts the truck off? The 3098 Mamba comes programmed to shut down automatically correct?
