Reply To: Battery question, need advice

When you equalize, this bypasses the bulk setting and allows the voltage to go to the highest point of the controller, (uncontrolled) which can be near 15 volts! It will set at this level for an hour or two and return to the float setting..

You must be careful when you equalize. Things can fry with the voltage being this high! You’re suggested to disconnect all loads and just let the controller work the battery alone..
