Battery with jst connector

Does anyone know where can I find a battery with suitable jst connector. I received the GSM/BLE board a month ago and still struggling to find a suitable battery.

Why seeed is not able to provide such a battery?

You can use any LiIon battery and connector from ebay, search for “Micro SH 1.0 2-Pin JST Connector with Wires” (sorry canno’t post the link).
