This is the Traxxas EZ-Peak Live Multi-Chemistry Battery Charger, with iD Auto Battery Identification. There has never been an easier or safer way to charge your batteries than with the Traxxas iD system. Now you can bring that technology to bear using your smartphone or tablet! Connect to the EZ-Peak Live app on your mobile device to experience a high definition graphical user interface. Your mobile device now becomes a powerful tool to check battery cell voltage, monitor charge status, create and store battery profiles, receive alerts, and access advanced user functions and information.

The EZ-Peak Live charger recognizes Traxxas iD batteries and in an instant automatically configures and optimizes the charger settings. There's no need to be a battery expert or learn how to navigate complex menus. Just plug in a Traxxas iD battery and the EZ-Peak Live does all the work for you. The integrated balance connector on Traxxas LiPo iD batteries eliminates fragile balance wires and connectors, along with the need for external balance boards. At the press of a button, the EZ-Peak Live Storage Mode protects your LiPo battery investment by safely preparing the batteries for extended storage. Advanced high-resolution peak detection deliver a perfect charge every time. Parental lock function for worry-free iD-only charging, or full manual control through the free Traxxas EX-Peak Live app.

NOTE: Accessing some charger features requires a mobile device with Bluetooth® capability (sold separately) and the Traxxas EZ-Peak Live Application. Available here for iOS and here for Android.

Traxxas EZ-Peak Live Multi-Chemistry Battery Charger w/Auto iD (4S/12A/100W)
The good: fantastic user interface, courtesy of the smartphone application. There is no easier setup. Plenty of profiles for different batteries (cell count and capacity). Good power, so it's fairly quick (I haven't charged any big packs - mine are 2S 5000-5500mAH size). Fan isn't too loud. Easy plugs if you make your own adapters.

The bad: the Bluetooth connection is atrocious - I sit 10' away and it's constantly disconnecting. This is the biggest drawback to the unit, in my opinion. It's also Traxxas-ID focused, so you'll have to buy/make adapters. My Batts all have XT60 connections, so I just adapted. I'm considering upgrading and getting a Dual Live, but I'm slightly worried about the BT sucking as badly.

Wish I would have spent the extra to get the one that could charge two batteries at once. Like most traxxas stuff, super easy too use. The blue tooth is actually nice for when you want to walk away. Can have my charger in the garage while I do stuff in the kitchen for example.
