Key Features: Spektrum Smart Technology Makes Charging and Maintaining Batteries Easy Integrated Microchip Stores Unique Parameters for Each Battery IC3 and IC5 Connectors are Compatible with EC3 and EC5 Save Time and Hassle, while Improving Battery Life Smart Discharge Allows Batteries to Automatically Discharge to a Safe Voltage Includes standard servo connector discharge lead for added convenience User Assignable Smart Discharge Allows Batteries to Automatically Discharge to a Safe Voltage Feature Overview: You’ll never have to set charge preferences for a Spektrum Smart battery until you want to. When a Spektrum Smart LiPo battery is connected to a Spektrum Smart charger, unique parameters and health of that Smart LiPo battery upload from the Smart memory microchip integrated into the battery. Through the charger, you can view and set preferences, such as charge rates, so that all you have to do to charge the pack every time is press the charger “Start” button. Smart technology takes care of the rest. Every Smart LiPo battery is factory assembled with the next-generation IC3™ or IC5™ output connector that’s conveniently compatible with older devices equipped with robust EC3™ and EC5™ connectors. You can use Smart Batteries with older systems, but only when connected to a Spektrum Smart device will all the benefits of Smart technology become obvious
