And you want to charge at 50mA so your resistor value is 80 ohms. 100 is the closest you will get which will charge at: 4/100 = 40mA. Edit: I should add that the current will vary as the batteries charge. So a discharged battery at 1.1V will charge at (18 - 11) / 100 = 70mA. This current will fall to 40mA as the battery comes up to full charge.
