Smart Technology
When connected to a Spektrum Smart charger, your Smart LiPo battery's unique parameters and health 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 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.

Simple & 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-customised, 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 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. The IC connector series is entirely backwards compatible with existing EC3 and EC5 connectors so you can use Smart Batteries with older systems.

Spektrum 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 helps extend your Smart Batteries' life by preventing batteries from sitting fully charged for an extended period, which can damage the chemical integrity of Lithium Polymer cells.
