iCharger S6 1100W 40A 6S DC Smart Battery Charger
The iCharger S6 is a compact, high-power DC smart charger designed for pilots who want serious charging performance in a small and portable package. Built as a more powerful companion to the popular X6, the S6 delivers up to 1100W of charging power and up to 40A charge/discharge current, while remaining close in size to smaller field chargers.
With support for up to 6S lithium batteries, strong balancing performance, regenerative discharge, and a full-color IPS display, the S6 is an excellent choice for RC helicopter, airplane, car, boat, and FPV pilots who need reliable, high-output charging at home or at the field.
Despite its compact size, the S6 includes many of the advanced functions iCharger users expect, including multi-chemistry battery support, internal resistance measurement, battery data logging, firmware upgrade support, and flexible charging/discharging options.
