    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.

    Spektrum Smart LiPo Batteries Store Unique Data, such as:
    • Battery Brand
    • Battery Type
    • Battery Capacity
    • Battery C Rating
    • Individual Cell Voltage
    • Battery Temperature
    • Charge/Discharge Cycles

    Spektrum Smart LiPo batteries also maintain an error log including the number of over-heat, over-discharge and over-charge incidents which can be helpful data in assuring that the battery you’ve chosen is right for the application. A Smart Battery uploads its charge parameters to a Spektrum Smart Charger automatically making charging as simple as pressing the “Start” button. The charge rate of every Smart Battery is customizable, allowing you to take full advantage of packs with faster charge ratings.

    Spektrum's 3S ECU battery are built with high-quality 9.9V Li-Fe battery cells designed specifically for turbine Electronic Control Unit (ECU) use while giving pilots all the benefits of Spektrum Smart Technology, all while remaining small and lightweight

    Smart Battery Technology

    When connected to a Spektrum Smart charger, unique parameters and health of your Smart LiPo battery upload from the Smart memory microchip integrated into the battery. Through the charger, you can set and record preferred settings, such as charge rates and self-discharge options, so that all you have to do to charge the pack is press the “start” button. Smart technology will take care of the rest. Every Smart LiPo battery is factory assembled with the next-generation IC3™ and IC5™ output connector that utilizes a data transfer wire to relay saved information to your Smart Chargers.

    Smart Battery Technology

    Data Rich

    An integrated microchip allows each Smart Battery to save vital information such as battery brand, chemistry, cell count, capacity, number of charging cycles, number of discharges, C rating, battery temperature, and internal resistance. Additionally, each battery will save a log of unhealthy events such as over-charge, over-discharge, and over-temperature. This allows you to make the most informed decision about each battery when you are getting your gear ready for a day at the field or the track.

    Data Rich

    Simple and Quick

    Preset charge, discharge, and storage parameters are automatically relayed from your Spektrum Smart Battery making charging as simple as pressing the “Start” button. Charge rate of individual batteries can be user customized allowing you to take full advantage of packs with faster charge ratings. The integrated microchip on each battery will remember the last charging rate you set, so the next time you plug it in, these settings will automatically populate so all you have to do is press “Start.”

    Simple and Quick

    New IC3 & IC5 Connectors

    The innovative Smart connection is made possible by an installed microchip on every battery, feeding the unique information through a data cable to the new IC3 and IC5 connectors. The IC series of connectors are designed from the ground up to provide a more solid connection, higher heat resistance, and effortless installation. For those using the popular EC3 and EC5 connectors, there’s no need to worry. The IC connector series is entirely backwards compatible with existing connectors so you can use Smart Batteries with older systems, but only when connected to a Spektrum Smart device are all the benefits of Smart technology obvious.

    New IC3 & IC5 Connectors

    Smart Discharge

    LiPo batteries with Spektrum Smart™ technology practically take care of themselves. When programmed with a Spektrum Smart Charger, Smart Batteries will automatically discharge to your predetermined storage voltage when they are left to rest for a time period you choose, between 12 and 240 hours. This feature will help to extend the life of your Smart Batteries by preventing your batteries from sitting fully charged for an extended period of time, which can damage the chemical integrity of Lithium Polymer cells. This unique feature results in longer battery life expectancy and better performance over the life of the pack.
