Spektrum Smart Powerstage 4S Surface Bundle: (2) G2 5000mAh 2S LiPo IC5 & S250 Charger

Spektrum^™ S250 AC 2x50W Smart Charger

With up to 50W power per channel or 80W on one channel for faster charging, plus the ability to charge batteries on either the IC3® or IC5® integrated output ports, the Spektrum™ Smart S250 2x50W Charger delivers a versatile and truly hassle-free charging experience. The S250 charger works with virtually any Smart battery and is backwards compatible with EC3™ and EC5™ connectors. Use it together with Smart G1 or G2 batteries and you'll be amazed by its incredible functionality and performance.

The S250 Smart AC Charger makes battery charging the easiest it has ever been. Its Auto Charge feature recognizes your Smart battery's parameters, such as chemistry type and charge rate, and begins safe, correct charging automatically when the charge lead is connected. A clock on the charger's screen counts down the time until your Smart battery is fully charged and ready to use.

Balancing Smart G2 batteries is just as simple. The S250 charger will balance your Smart G2 LiPo packs through the same, single IC connection used for charging. No separate, confusing balance leads are required.

The S250 Smart AC Charger's user interface features fresh, intuitive menus, icons, and navigation tools. Its clear, easily understandable indicators of Smart battery history and performance provide the information you need to make the best decisions about your batteries when putting gear together for a day at the field or track.

The USB-C port is exclusively for firmware updating so you always have the latest version. The S250 Smart AC Charger also includes a cooling fan, detachable power cord, and sleek case that fits perfectly on your workbench and in your pit or field bag.

Spektrum 7.4V 5000mAh 2S 50C Smart G2 Hardcase LiPo IC5 Battery (Two Batteries Included)

Drivers 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.

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.
