Industry Innovation for Smarter, Safer and Simpler RC Battery ChargingSmart Batteries give you a safer and simpler connection to your hobby that puts you in complete control, makes you more aware and more confident about the capability of your equipment - all the while making your hobby easier.LiPo batteries with Spektrum Smart Technology practically take care of themselves. When combined with a separately available Spektrum Smart Battery Charger, the unique parameters, health, and history of that battery are all available the instant it's connected - thanks to an integrated microchip in each Smart Battery. Through the charger, you can view and set preferences, such as charge rates, so all you have to do to charge the pack every time is press the charger "Start" button. Smart technology takes care of the rest.Spektrum Smart LiPo Batteries store unique data, such as:BrandType (Chemistry)CapacityC RatingInvdividual Cell VoltageBattery TemperatureCharge / Discharge CyclesSmart LiPo battery packs are also programmable to meet your exact charging needs if you choose. But the crowning feature of a Spektrum Smart LiPo battery is that it can be programmed to safely self-discharge to storage condition. That's a Smart Battery pack!Key Features:Spektrum Smart Technology makes charging and maintaining batteries easyIntegrated microship stores unique parameters for each batteryNew IC3 and IC5 connectors are compatible with EC3 and EC5Save time and hassle, while improving battery lifeSmart discharge allows batteries to automatically discharge to a safe voltageIncludes:Smart LiPo Hard Case Battery Pack 5000mah 3S 11.1V 30C with IC3 Connector (SPMX50003S30H3)Specifications:Application: RC Surface (Car, Truck)Battery Type: Smart LiPoBattery Voltage: 11.1VCapacity: 5000 mAhConnector Type: IC3Hard Case: YesMaximum Continuous Discharge Rate: 30CNumber of Cells: 3Height: 1.5 inches (39mm)Length: 5.5 inches (139mm)Width: 1.8 inches (46mm)Weight: 0.9 pounds (410 grams)
