There is no direct correlation between amps input and amps output. It's power (in Watts) you need to consider.

Power = Volts x Amps

So if you have your power supply set to 18V and it's capable of 30A then it's max power is 540 Watts (18V x 30A = 540W)

On the output side if you were charging a 6s battery (25.2V max) at 14.4 Amps then you need 363 Watts (25.2V x 14.4A = 363W)

So that's fine, your power supply has plenty of headroom (allow at least 15% surplus for supply power vs charging power)
