I am using a 20amp adjustable voltage power supply from DROK as a charger and it's' worked great up to today when something changed. It does not have the adjustable current knob.
Behavior before: The voltage with no load would be set at 14.4v to 14.6v and then when you hooked it up, the voltage would drop to 13.something on the screen and gradually increase as the SOC increased ultimately ending with the display showing the non-load setting of 14.4v and charging would stop.
Behavior today: Same settings, but now the displayed voltage of 14.6v does not drop when hooking it to a battery in need of charge. It remains at 14.6v and multi-meter measurement shows it is putting out that voltage. It seems to go through the same cycle of heating up and running the fan as needed and the battery seems to charge just fine.
Any thoughts on what may have broken perhaps with the power supply? Why is it suddenly not varying voltage under load?
