Put a small value, precision shunt resistor in series with the cell and measure the voltage drop across it.

A current shunt is just throwing away energy. Granted that it is a small amount but, if it can be avoided it should be. The use of a Hall sensor would be my first choice. Search ebay and you will find Hall sensors ranging from 5A to 30A .
