It's fine. You can't push more current through so you don't need the other wires. It's essentially, a slightly smarter, slow charging lipo wall wart. It detects and balances voltage between each cell as it charges. That's all you need. Just don't charge anything unattended.
My madbull charger is the exact same thing and only uses the balancing plug to charge. But my Imax B6, on the other hand, can push a lot of current into lipo and life batteries to charge them very quickly. But it can also charge NiCad, NiMH, lead etc...
