Set LVC at around 15.5v, and plug it all up. It should initialize fine, and give the yellow light I believe. You may only get a second or two of power, if so...turn off switch and back on. Yellow light should be back. Then give it slight throttle and hold it at that position for a while. It should act alright once the voltage drops to around 20.4v. That should get you running though, its a pain...but its not made for 5s.
