I recently bought a Weize 48v 100ah server rack battery and an AIMS 48v 25a charger for use as a UPS with a 3000 W 48 v inverter. When I first connected them everything worked fine, the battery charged. I adjusted the charge current and the plastic adjustment knob/screw fell out. Now I only get a red error light when trying to charge, even though the adjustment screw snapped back into the current control resistor and seems to still work over the 0%-100% range and hits the stops. Any ideas other than trying to replace the control completely? The charger red error light is on solid - with no charge. Cannot find any service or warranty info for AIMS.
