current indicator

1 Watt white led as a current indicator

I added a 1 watt led, rated for 350ma, which will drop the output voltage a bit, and light up when the pack is being charged.
I have blown out several leds on the first pulse when the charger was connected to the pack. A 20 ohm 5W resistor to shunt some of the current around the LED and run it at a lower current should fix this problem.
