Overview
Spektrum Smart G2 50C LiPo batteries make charging and storage simpler and safer. Balancing information travels through the unique data wire of each Smart G2 battery's IC3 or IC5 connector, so only a single connection is needed — no separate balance lead is required. G2 batteries come factory-programmed to discharge automatically to a safe storage voltage of 3.90V after 72 hours of inactivity, offering longer battery life and maintenance-free peace of mind. The storage discharge rate is three times faster than previous G1 Smart batteries.
An integrated microchip stores each battery's unique parameters — including brand, chemistry, cell count, capacity, charge/discharge cycles, temperature, and internal resistance — and maintains an error log of over-heat, over-discharge, and over-charge incidents. When connected to a Spektrum Smart charger, this information uploads automatically and charging begins without any manual setup.
Note
All G2 batteries require a Spektrum Smart Charger with G2 firmware. IC3 and IC5 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.
Features
- Simpler and safer to use
- Powerful 50C continuous discharge rating to deliver high performance and longevity
- Balance charge through the IC3 or IC5 connector data wire — with only one connection, no balance lead required
- Faster Auto Discharge at up to 1.5A to safe storage voltage for long battery life and improved performance
- Thicker internal metal side plates protect cells and improve heat dissipation
- Integrated microchip stores unique parameters for each battery
- IC3 and IC5 connectors are also compatible with EC3 and EC5 styles
- Spektrum G2 Smart Charger required (or earlier Smart Charger with G2 update)

- Note: G2 batteries require the use of a Spektrum™ G2 Smart Charger or earlier Smart Charger with G2 update.
Highlights

Smart G2 single-connection balance charging
When connected to a Spektrum Smart charger, balancing information travels through the IC5 connector's data wire so only a single connection is needed — no separate balance lead required.

Data-rich integrated microchip information display
An integrated microchip allows each Smart G2 battery to save vital information including cell count, capacity, charging cycles, C rating, temperature, and internal resistance.

Smart Auto Storage Discharge feature
G2 batteries come from the factory programmed to automatically discharge to a safe storage voltage of 3.90V after 72 hours of inactivity.

Simple plug-in charging with Smart charger
Preset charge, discharge, and storage parameters are automatically relayed from the Smart G2 battery to your Smart charger, making charging as simple as plugging in the pack.

IC5 connector and data wire detail
Spektrum Smart IC5 connectors have been designed to provide a more solid connection, higher heat resistance, and effortless installation, and are backwards compatible with EC5 connectors.
