Power Shield - Max Charge Current

The Power Shield currently states that the max charge current for other DC sources is 1A. Does that mean the max amount of current it will be charging the battery at or the max amount of current that is allowed in the the DC input?

The charge current is set to 500mA when charging from USB and set to 1A when charging from a DC source.

It is the current flowing into the battery and charging it.


Thanks for info!
