I got a Hyperion 0610i Duo II charger and bought a IP 5000mAh 40C lipo battery.

However, the balancing plug is a little one with 3 pins. My charger's balancing has only 4 pins or much bigger.

What should I do? Any suggestion? Thank you.

The Duo (or any of the Hyperions) used to come with only the Hyperion style balance adapter board. There are 3 other types of balance plugs in popular use so you need one of the other adapter boards. The other types are the JST-XH (also called the Align style), Thunderpower type, and the Kokam type conmnector. There are two that could be called 'small' connectors. Look at the listings here and see if your lipo is listed - it'll tell you which adapter board you need to buy -

What brand is your lipo?

I'm using Intellect 5000Mah 50C Lipo. Yes my DuoII comes with the adapter board, however, they all are 4-pin. The plug that comes with the battery is 3-pin and much smaller.

Would the JST-XH works with my DuoII?

Unless you have a strange balance adapter board, the board should have a 3 pin connection for a 2S. They are all made this way, I have one of each type adapter board sold by Hyperions and they all have a 3 pin socket on the board for connectiong a 2S lipo balance plug. Maybe you have something different?

That appears to be a JST-XH plug on the linked lipo and you'd need this -
