The Traxxas® EZ-Peak Live™ App connects wirelessly via Bluetooth® to the Traxxas EZ-Peak Live multi-chemistry charger (#2971). The app transforms your iOS device into a powerful tool to access the charger’s advanced features with an easy-to-use graphical interface. Connect up to four chargers to your iOS device to monitor charge status, receive remote alerts, and access the charger’s manual settings. The Traxxas iD system is the easiest and most efficient way to charge your iD-equipped batteries. When you connect an iD-equipped battery to your EZ-Peak Live charger, the battery’s information will automatically be displayed on the app screen. The app allows you to instantly verify your battery’s status and individual LiPo cell voltages with clear and precise readouts. Use the charger’s automatic settings or configure your own with the easy-to-use sliders and buttons on the high-definition graphical interface. Once charging has begun, the app allows you to monitor the status of up to four connected chargers remotely. Receive real-time updates with charge times, charge progress, mAh input, and estimated time remaining. The app will alert you once the charging cycle is complete or you may also stop the charging cycle at any time. Remote monitoring via the EZ-Peak Live App works within the range of your Bluetooth connection, but remember to always be present to supervise the batteries being charged. Charging non iD-equipped batteries on your EZ-Peak Live charger requires access to the manual settings. The EZ-Peak Live App is the only way to access these settings. The handy Charge Settings Wizard makes non-iD battery setup a breeze. Helpful menus with high definition images help identify battery types and provide clear and precise instructions. Bold buttons and sliders allow you to choose your settings from the display. Safety is a prominent feature of the EZ-Peak Live app. The EZ-Peak live charger can be placed in iD Only mode to prevent unauthorized users from accessing the manual settings. It’s a great solution for a charger that will be used in households where there are multiple battery types and different levels of knowledge about batteries and charging. An easy-to-use passcode system restricts unauthorized access to the manual settings while keeping all other functions enabled. • View individual cell voltages of LiPo batteries • Monitor charge status with voltage readout, estimated time remaining, and energy added (mAh) • Configure your charge settings with the easy-to-use graphical interface • Access manual charge settings for non iD-equipped batteries • Recognizes and remembers settings for up to four connected chargers • Passcode protected iD-Only mode prevents unauthorized access to manual charge settings • Create battery profiles and store commonly used settings • Alerts you when firmware updates are available and uploads them to the charger
