It looks like it balances during charging to me - they do call it a "balance charger" as well.
Re. "fast mode": most LiPo's have a max charge rate (often 1C), so you generally can't go any faster than this.
Those round-pin connectory are rubbish for high currents - the CORE UDC-20 comes with a similar connector set, and when I tested them I found they had a relatively high resistance causing a large voltage drop across the connector, leading to the charger thinking it hit the terminal voltage early on and reducing the current, hence increasing the charge time. Nothing that a couple of minutes with a soldering iron and some chunky wire won't sort out though.
