Overview
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 (available at spektrumrc.com).

Frequently Asked Questions
- What is SMART G2 technology and why should I choose it over standard LiPo batteries? — SMART G2 technology features an integrated microchip that stores your battery's charging parameters and health information. When you connect a SMART G2 battery to a compatible Spektrum Smart charger, the battery automatically uploads its settings, eliminating manual configuration. The battery also automatically discharges to a safe 3.90V storage voltage after 72 hours of inactivity, extending lifespan and reducing maintenance. This intelligent approach makes charging foolproof whilst keeping your battery in optimal condition between uses.
- Is this battery compatible with my RC vehicle? — If your RC vehicle accepts 2S LiPo batteries with IC3 connectors, this battery will be compatible. The ARRMA TYPHON MEGA 665 4x4 RTR brushed buggy, for example, comes factory-equipped with a 40A LiPo-ready ESC with IC3 connectors, making it a perfect match. Check your vehicle's manual or specification sheet to confirm 2S and IC3 compatibility before purchasing.
- What charger do I need to use this battery? — You'll need a Spektrum SMART charger to take full advantage of the SMART G2 features. The S100 1x100W USB-C Smart Charger is an excellent choice that works seamlessly with this battery, automatically detecting its parameters and optimising the charge cycle. Other Spektrum SMART chargers will also work with this battery.
- How long will this battery power my RC vehicle? — Runtime depends on your specific RC vehicle, its motor, ESC settings, and driving style. The 5000mAh capacity provides substantial run time for most 2S-powered RC buggies and trucks, typically ranging from 15-30 minutes depending on vehicle weight, motor power, and terrain. More aggressive driving consumes power faster; smooth driving extends runtime.
- What does the 50C discharge rating mean? — The 50C rating indicates the maximum continuous current the battery can safely deliver, calculated as the capacity multiplied by the C rating (5000mAh × 50 = 250 amps maximum continuous discharge). This high rating ensures the battery can power demanding brushless motors, aggressive acceleration and sustained high-performance driving without voltage sag or performance loss.
- How should I store this battery? — Leave the battery connected to power or store it in a cool, dry location. The SMART G2 technology automatically discharges the battery to a safe 3.90V storage voltage after 72 hours of inactivity, so you don't need to manually manage storage procedures. Always store LiPo batteries away from flammable materials and never leave them unattended whilst charging.
- What is the difference between the single connection IC3 system and traditional balance charging? — Traditional LiPo batteries require a separate balance connector (typically XH or 2S balance lead) in addition to the main power connector, meaning two connections to charge properly. The SMART G2 integrates balancing information into the IC3 connector's data wire, requiring only a single connection to your Smart charger. This reduces complexity, minimises potential failure points, and speeds up the charging process whilst ensuring perfect cell balancing.
- Can I use this battery with non-Smart chargers? — While this battery can technically charge on standard LiPo chargers using the IC3 connector (with an adapter if needed), you'll lose the intelligent SMART G2 features like automatic parameter detection and optimised charging profiles. A Spektrum SMART charger is recommended to unlock the full benefits of this technology.
- Is this suitable for beginners to RC hobbies? — Absolutely. The SMART G2 technology actually makes this battery ideal for beginners because the intelligent charging eliminates the need to understand manual charge rate settings, balance charging procedures, and storage protocols. Simply connect to a SMART charger and let the battery's microchip handle the rest. The foolproof design reduces the learning curve significantly.
