This is the Traxxas EZ-Peak Dual Multi-Chemistry Battery Charger System with two included "Power Cell" Batteries. This charging system uses the Traxxas iD Battery Identification System and is a great solution when you need batteries and a charger for your Traxxas vehicle that runs either one or two 2S LiPo batteries. Even if your Traxxas vehicle requires only one battery, you can still take advantage of this system and have two batteries on hand for extended driving excitement. iD Simplicity With iD Auto-Battery Identification theres no need to worry about the battery chemistry or capacity. EZ-Peak Dual identifies the type of battery and its capacity. EZ-Peak Dual also cuts down on wasted time by eliminating the hassle of programming and using complicated setups. Just plug an iD battery in and press Start. That it! Keeping with the simplicity and ease of use, the iD system eliminates fragile balance wires and clunky balance leads. The iD system streamlines the entire charging experience. Traxxas' Most Powerful Charger Faster charging means you get to spend more time behind the wheel. The EZ-Peak Dual puts out a full 100 watts of power that equates to 8-amps of charging horsepower. It's a twin turbo-equipped charger. Traxxas iD LiPos (4000mAh or higher) charge nearly 2x faster in High Output Mode. The EZ-Peak Dual isn't just for iD LiPos; the Multi-Chemistry nature of the charger means LiPos and NiMHs can be charged at the same time. Advanced Mode opens the door for backwards compatibility. This allows EZ-Peak Dual to charge any Traxxas Power Cell battery equipped with a first-generation Traxxas High-Current Connectors and Traxxas iD batteries independently or simultaneously. There are two balance ports built into the charger for Traxxas LiPo batteries equipped with external balance leads. Take full advantage of the 8-amp output and experience the pinnacle of charger flexibility and power.
