I have a 100ah lit-ion battery that tests 3.5v with nothing attached (seems deeply discharged) and when I hook up the IP65 it immediately goes into absorption mode. Testing the voltage with the IP65 attached shows 14.4v, but no current being sent according to the Connect app. I've let it sit charging that way overnight, but as soon as I take the charger off and test the voltage of the battery, I'm back down to 3.5v. Any ideas why I can't push any current to this, or why it won't charge? Thanks!
