5000mAh 4S LiPo & S155 Charger (SPMXPSS400)

Spektrum Smart Powerstage 4S Bundle pairs a 5000mAh 4S Smart G2 LiPo with the S155 55W AC Smart Charger to deliver a complete, easy-to-use charging solution for four-cell RC packs. With Spektrum Smart technology, charging and balancing happens through a single IC3 or IC5 data wire, so no separate balance lead is required.

Designed for 4S configurations, the bundle includes a 5000mAh 4S LiPo (14.8V) with a 50C discharge rating, and a charger capable of handling 4S LiPo/LiFe/Li-Ion/LiHV as well as 1-12S NiMH/NiCd packs. The S155 features a color LCD with intuitive menus, a real-time charge countdown, a USB port for firmware updates, a detachable power cord, and sleep mode. The Smart G2 battery stores its charging parameters in an integrated memory microchip and uses a single data wire for balancing through IC5, with automatic storage to 3.90V after 72 hours of inactivity. This setup provides a safer, simpler charging experience and helps maximize battery life for RC cars, planes, boats, and other models.
