Smart Battery Technology
Every Spektrum Smart battery communicates with Smart chargers via the IC series data wire. This enables preset and custom charge, discharge and storage parameters to be applied automatically, making routine charging quick and consistent.
Data Rich
The onboard microchip records and shares useful information to help you manage your packs:
- Brand, chemistry, cell count and capacity
- C rating and internal resistance
- Individual cell voltages and battery temperature
- Charge and discharge cycle count
- Event log for over-charge, over-discharge and over-temperature
New IC3 & IC5 Connectors
The IC series connectors are designed for a solid electrical connection and higher heat resistance, with an integrated data line for Smart communication. Suggested compatibility with existing EC3/EC5 systems is provided via the IC series design; full Smart features require a Spektrum Smart charger.
Smart Discharge
When configured on a Smart charger, the pack can automatically discharge itself to your chosen storage voltage after a user-defined delay (12–240 hours), helping preserve cell integrity and extend service life.

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.
Our new Spektrum Smart 50C LiPos come in a variety of popular sizes and are ready to drop into your RC car or boat for better performance, power, and reliability. These battery packs are a great upgrade for those looking to get more punch and off the line power on nearly any setup.
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.
Smart Battery TechnologyWhen 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.
Data RichAn 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
Simple and Quick
Preset charge, discharge, and storage parameters are automatically relayed to a Spektrum Smart Charger 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.”
New IC3 & IC5 ConnectorsThe 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.
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.
