Traxxas iD batteries deliver an easier and safer LiPo charging solution when used with our exclusive iD chargers. You just plug in your iD batteries and press start. The iD charger handles all the settings and quickly gives you an optimized charge, every time. The new 4s capable EZ-Peak Live multi-chemistry charger is our newest and most advanced charger, equipped with built-in Bluetooth to work seamlessly with the new Traxxas EZ-Peak Live app for iOS and Android. The EZ-Peak Live app gives you detailed information, remote monitoring, and advanced operating functions through the high-definition color interface on your mobile device. It's our finest charger in the popular EZ-Peak iD lineup. Along with the new technology, we added more charging power, up to 12-amps for 2s LiPo batteries! Your batteries are charged faster so you can get back to the fun of driving sooner. The EZ-Peak Live puts out a full 100 watts of power—that equates to 12-amps of charging horsepower! The charger automatically detects the size of your iD-equipped battery and configures the settings for the fastest charge possible. NiMH batteries charge faster than ever with a full 5-amps of charging power. LiPo batteries charge even faster with up to 12-amps of colossal power! A balance port is built into the charger for LiPo batteries equipped with external balance leads. The free EZ-Peak Live App installs on your Apple iPhone, iPad, iPod touch, or Android device and links to your charger via built-in Bluetooth. The EZ-Peak Live App gives you access to additional features, such as a high-definition graphical user interface, firmware upgrades, remote monitoring and alerts for up to 4 chargers, detailed live charging information, and the ability to turn off iD mode. iD mode may be switched off through the EZ-Peak Live Application for charging first-generation Traxxas batteries with non-iD High-Current Connectors. This is charging the Traxxas way—fast, easy, and more advanced than ever!.
