I have a 12.4V / 4Amp diode protected transformer with a bridge rectifier and a 10000 MFD Capacitor @16V. I wish to connect this to the smart controller to use as a battery minder when in storage. Battery is an AGM Lifeline 105Ah. When I measure the transformer output I see an AC ripple of 900 millivolts. Can the smart charger handle this.
