Drivers and pilots enjoy even more Smart advantages when using Spektrum Smart G2 50C LiPo batteries to power their vehicles. New "Generation 2" features make these LiPo packs — featuring a 50C continuous discharge rating for high performance and longevity — even simpler and safer to use together with your Smart charger.

For example, Spektrum Smart G2 technology makes it much easier to balance charge your LiPo batteries. Balancing information travels through the unique data wire of each Smart G2 battery's innovative IC3 or IC5 connector. As a result, only a single connection is needed — no separate balance lead is required.

Smart G2 batteries come from the factory programmed to discharge automatically to a safe storage voltage of 3.90V after 72 hours of inactivity. The benefits include longer battery life, better performance over the life of the pack, and the peace of mind that comes from knowing your Smart battery is maintenance-free. You can change the battery's Auto Storage settings based on your own preferences. G2 batteries also offer a storage discharge rate that's three times faster than the previous G1 Smart batteries.

Smart G2 30C soft-case LiPo packs also include thicker internal metal side plates. These plates improve heat dissipation and provide more protection for the cells against punctures during rough landings or in similar impact-prone situations.

As with other Smart batteries, you'll never have to set your own charging preferences for a Spektrum Smart G2 battery until you want to. When a Smart G2 LiPo battery is connected to a Spektrum Smart charger, its unique charging parameters and health information upload to the charger from the battery's integrated memory microchip. Through the charger you can view and set preferences such as charge rates, so all that's required to charge the pack is connecting it to your Smart charger. Smart technology takes care of the rest.

Spektrum Smart G2 50C LiPo batteries store a wide variety of essential information, including:

  • Battery Brand
  • Battery Type
  • Battery Capacity
  • Battery C Rating
  • Individual Cell Voltage
  • Battery Temperature
  • Charge/Discharge Cycles

Spektrum Smart G2 LiPo 50C batteries also maintain an error log including the number of over-heat, over-discharge and over-charge incidents. This data can be helpful in assuring that the battery you've chosen is right for the application. Innovative Spektrum Smart G2 LiPo 50C batteries are so easy to use, they nearly take care of themselves. It's easy to achieve peak battery performance, reliability and longevity with Smart G2 technology!

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

Smart Battery Technology — One Smart Connection

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
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
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<sup>®</sup> and IC5<sup>®</sup> Connectors
IC3 and IC5 Connectors

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 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.

Spektrum RC 4S Smart G2 LiPo 50C Battery Pack (14.8V/5000mAh)
If you’ve used the gen1 batteries then it’s pretty much the same thing. Don’t really notice a difference in performance but the ease of use and reliability is top notch. The battery is pretty much dummy proof with a spektrum smart charger. If your still rocking the gen 1 smart charger pick up the adapter to update it and you’ll be able to use these gen 2 batteries. Yes, you can pick up cheaper batteries, but you are paying for the convenience. Not having to worry about storage charge and balance leads is nice. I like that I can just fully charge all of them and forget it. It’ll self discharge after my setting of 72h, having to discharge lipos via charger takes forever. The extra perks of checking your battery health and history is nifty perk. If your starting to get into horizon hobby products then start out with 8S smart charger bundle and go from there.
