Drivers and pilots enjoy even more Smart advantages when using Spektrum Smart G2 50C LiPo batteries to power their vehicles. 
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.
