The regulator is only suitable for lead-acid batteries: OPEN, AGM, GEL. Not suitable for NiMH, Li-ion or other batteries. 2. Make sure your battery has enough voltage for the controller to recognize the battery type before first installation. 3. The battery cable should be as short as possible to minimize loss. 4. The charge controller is only suitable for regulating solar modules. Never connect another charging source to it. 5. The controller will be hot when running. Please install it in a well ventilated place.
