I cannot seem to charge my run battery at the same time i am using an inverter .
I am trying an experiment to charge a run battery supplying power to an inverter that is used to make more DC voltage. I Can charge an alternate battery, but when i connected to the run battery it drains to fast and the inverter stops working. I have a diode on the positive so no drain there. How Can i allow charge voltage in at the same time as running an inverter?
