It could easily run dual 380s. I only purchased one but i even ran 28.8 volts through it with no load for maybe a min on and off the throttle with a 700 motor on the line. I am quite impressed despite the slandering of cheap chinese products i give it a hundred stars. One thing if you do give it higher voltage i would check your bec voltage before hooking up a reciever. At 21.6v it was 6. something but at 28 spiked up to 6.9 which most would say is unsafe for a reciever and highly un recommended for a servo as it will create a ton of heat
