Product Description

Streamline your power management workflow and maximize bench efficiency with the Spektrum S155 55W AC G2 Smart Charger. This compact, budget-friendly single-channel charger delivers 55W of reliable continuous output at up to 5.0A, providing an optimized charging solution for the radio control hobby market, FPV drone racers, and agile multirotor pilots. Featuring Spektrum's proprietary Generation 2 Smart technology, the S155 introduces Auto Charge simplicity by instantly recognizing preset cell capacities, chemistries, and performance logs from Smart batteries to execute high-accuracy charging routines. It facilitates one-connection charging and balance-sensing directly through integrated, selectable IC3 and IC5 output ports, entirely eliminating the need for independent, fragile balance leads while remaining backward-compatible with standard EC3 and EC5 connectors.

Designed with versatility and strict operational safety in mind, this multi-chemistry charger accommodates LiPo, LiHV, LiFe, LiIon, NiMH, and NiCd cells from micro 1S packs up to high-voltage 4S setups. The S155 G2 incorporates comprehensive short-circuit, over-current, reverse-polarity, and thermal protection protocols, making it a safe, foolproof tool for educational environments like high school robotics clubs and university aerospace engineering departments. Additionally, its vibrant color LCD screen features a real-time countdown clock and an intuitive user interface, matching the rugged equipment profiles demanded by commercial sUAS manufacturers, drone contractors, and tactical military unmanned operations needing reliable power management in the field.
