I just purchased a Hitec X4 for use with Typhoon H batteries. I'm aware of the wattage limitation but even when charging at 2.0 amps on 4S, the charger will shut off after a minute or two and does not show any error message. It does it every time. The screen looks just like it does before the long press to start it up. It does this on all 4 ports on any of my 4 batteries, all of which charge fine on the Yuneec charger. I also have a voltmeter and there is no apparent issue like grossly out of balance cells. This is my first use of this charger but it doesn't seem that hard to set up. Am I missing something?
