For that battery I would do 0.28 amps or if it has a 2c charge rate (the 30c is your discharge rate) you could go to 0.56 amps. But I would not go over this. You will want to set the charger to LiPo and set it to 2s or 7.4 volts (this is a nominal voltage). And since it is a 2 cell pack, I would charge it on balance mode.
Here is a video from HiTec on setting this charger up for charging a LiPo battery.
