Smart Powerstage 4S Surface Bundle: (2) G2 5000mAh 2S LiPo IC5 & S250 Charger (SPMXPSS500)

Spektrum Smart Powerstage 4S Surface Bundle is a complete, high-performance charging and power kit for surface RC models. It combines two 5,000mAh 2S Smart G2 hardcase LiPo batteries with the S250 AC Smart Charger in one ready-to-run package, delivering a simple, one-box solution for field or pit charging. With up to 50W per channel (80W on a single channel) and the ability to charge both packs at once, this bundle keeps vehicles ready to drive and minimizes downtime.

Smart G2 technology automates charging by reading each battery’s parameters and balancing through a single IC connection—no separate balance leads required. The S250 features a color LCD interface for easy navigation and supports a wide range of packs (1-4S LiPo/LiFe/LiIon/LiHV and 1-12S NiCd/Smart NiMH). Each battery’s memory microchip stores its unique settings, ensuring optimal charging every time. Additional conveniences include a USB-C port for firmware updates, a cooling fan, and a compact case that fits neatly on a workbench or in a pit bag.
