Smart Battery Technology — One Smart Connection

When connected to a Spektrum^™ Smart charger, a Smart G2 battery's unique parameters, health, and balancing information upload automatically from its memory microchip through the IC3^® or IC5^® connector's data wire. To charge and balance the pack, you simply connect it to your Smart charger. Safe charging begins automatically, and no separate balance lead is needed.

Data Rich

An integrated microchip allows each Smart G2 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 to go out and have fun.

Smart Auto Storage Discharge

Spektrum^™ Smart G2 batteries practically take care of themselves. G2 batteries come from the factory programmed to automatically discharge to a safe storage voltage of 3.90V after 72 hours of inactivity. The results are longer battery life, better performance over the life of the pack and peace of mind that your Smart battery comes maintenance-free. The battery's Auto Storage settings can be changed by the user based on preferences.

Simple and Quick

Preset charge, discharge, and storage parameters are automatically relayed from your Spektrum^™ Smart G2 battery to your Smart charger, making charging as simple as plugging in the pack. Charge rate of individual batteries can also be user-customized, allowing you to take full advantage of packs with faster charge ratings. The battery's integrated microchip remembers the last charging rate you set, so the next time you plug it in, these settings will automatically take effect.

IC3® Connector

The innovative Smart connection is made possible by a microchip installed in every battery, which feeds the battery's unique information through a data cable to its IC connector. Spektrum™ Smart IC3® connectors have been designed from the ground up to provide a more solid connection, higher heat resistance, and effortless installation. IC connectors are also backwards compatible with EC connectors so you can use Smart batteries with older systems. Smart G2 batteries can be charged only with Smart chargers.
