All Systems Go! You'll never have to set charge preferences for a Spektrum Smart battery until you want to. When a Spektrum Smart LiPo battery is connected to a Spektrum Smart charger, unique parameters and health of that Smart LiPo battery upload from the Smart memory microchip integrated into the battery. Through the charger, you can view and set preferences, such as charge rates, so that all you have to do to charge the pack every time is press the charger 'Start' button. Smart technology takes care of the rest. Our new Spektrum Smart 100C Lipos come in a variety of popular sizes and are ready to drop into your RC aircraft for maximum performance, power, and reliability. These are the perfect packs for pilots that need to get every last electron of performance out of their setup. Faster punches, less resistance to quick current load changes, and superior performance for 3D and EDF pilots.
