You can not charge through the balance port all that is for is when you do a balance charge it will monitor the cells to make sure they charge evenly.
No matter what charge mode you use the charging will be done through your deans plug, your charger should have a port where a deans plug can be plugged in so you can plug your battery into it. You dont have to hook the balance plug up in order to charge, the only time it will be used is when you do a balance charge.
