Smart G2 Powerstage Bundle for Surface 4S

Smart G2 Powerstage 4S Surface Bundle: 2S 5000mAh LiPo Battery (2) / S2200 G2 Charger              The Smart G2 Powerstage bundle is a one-box solution for vehicles  requiring top performance. Designed with the simplicity of Smart G2  Technology, this bundle includes (2) 5000mAh 2S 50C Smart G2 LiPo  Batteries, and (1) S2200 Smart G2 Dual Port AC Charger.        SPEKTRUM SMART G2 BATTERY Drivers enjoy even more Smart advantages when using Spektrum™ Smart  G2 50C LiPo batteries to power their vehicles. "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. G2 batteries also offer a  storage discharge rate that's three times faster than the previous G1  Smart batteries.
