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
- Do I need a special charger for the Spektrum Smart G2 50C battery? — Yes, this battery requires a Spektrum Smart charger to operate. The integrated microchip communicates charging parameters and battery health data through the IC3 connector's data wire to the Smart charger. Older standard LiPo chargers cannot recognise or safely charge Smart G2 batteries. If you don't already own a compatible Smart charger, you'll need to purchase one separately — it's a one-time investment that will work with all your future Smart batteries.
- What is the advantage of the single IC3 connection over traditional balance connectors? — The single IC3 data connection eliminates the need for a separate balance lead with multiple small connectors, which can be fiddly and prone to loose connections. All balancing information travels through the IC3 connector's integrated data wire, making the setup simpler, faster, and safer. You simply plug in one connector and the charger automatically receives all the information it needs from the battery's microchip to perform a perfect balance charge.
- How long does the automatic storage discharge take? — The Smart G2 battery automatically discharges to safe storage voltage (3.90V per cell) at a rate up to 1.5A, which is three times faster than previous generation Smart batteries. The exact time depends on the battery's current voltage and the 1.5A discharge rate, but most users can expect the process to complete within several hours of the initial 72-hour inactivity period.
- Can I use this battery with my older RC equipment that has EC3 connectors? — Yes, the IC3 connector is backward compatible with EC3 style connectors, so you can use this battery with older RC vehicles and aircraft equipped with EC3 sockets. However, you will still need a Spektrum Smart charger to charge it safely — the backward compatibility applies only to the discharge connector, not the charging system.
- Is the Smart G2 50C battery suitable for beginners? — Absolutely. In fact, the Smart G2 is particularly well-suited to beginners because it removes much of the complexity from battery management. You don't need to worry about setting charge rates or balancing parameters — the battery communicates this information to your Smart charger automatically. The automatic storage discharge means your battery stays in optimal condition without maintenance. However, you must use a Spektrum Smart charger, so if you're completely new to the hobby, budget for both the battery and an appropriate charger.
- What does the 50C discharge rating mean for my RC vehicle? — The 50C rating indicates the maximum continuous current the battery can safely deliver. For a 3200mAh battery, this means maximum continuous discharge of 160 amps (3.2A × 50C). In practical terms, this high discharge rating means the battery can power high-performance RC applications including aerobatic aircraft, racing drones, and competitive RC cars without voltage sag or performance loss during aggressive acceleration and manoeuvring.
- How many charge cycles will this battery last? — Smart G2 batteries are built for longevity, and the battery's microchip tracks charge cycles to help you monitor battery health. Typical LiPo batteries provide 300-500 quality charge cycles, but this depends heavily on how you use and store the battery. The Smart G2's automatic storage discharge and thermal monitoring help extend service life by maintaining optimal cell conditions between uses. Avoid over-discharging below 3.0V per cell, and store the battery in a cool location for maximum lifespan.
- What makes Smart G2 different from standard LiPo batteries? — Smart G2 batteries include an integrated microchip that stores and communicates battery-specific information such as capacity, cell count, C-rating, temperature, and a comprehensive health log. This data automatically uploads to your Spektrum Smart charger, allowing automated, optimised charging without manual settings. Additionally, the single IC3 data connection eliminates balance leads, and the automatic storage discharge maintains battery health without user intervention — features not found on standard LiPo batteries.
- Is this battery waterproof for use in wet conditions? — Whilst the battery itself is not waterproof, it's designed to function in wet environments typical of outdoor RC flying and driving. The soft-case construction provides protection, but you should avoid submerging the battery or allowing water to reach the IC3 connector. Always store and charge the battery in a dry location, and inspect the connector for water before connecting to your charger.
- What is the weight and size of this battery? — This battery weighs 385 grams (13.58oz) and measures 142mm length × 42mm width × 26mm height. These dimensions make it suitable for most standard RC vehicles and aircraft used in the UK hobby market. Before purchase, verify that your specific RC model's battery compartment can accommodate a 142mm long pack of this height and width.
