Hopefully it is not a counterfeit.

I finally got this project wired up.  Now what if the CHG line doesn't have a system load?  You know, something the battery would normally power if not charging.  I'm just looking to charge the 2 lipo batteries w/o a system load.  I thought maybe the CHG pin would have to be tied to GROUND.  Is that true?  Otherwise it looks as if the indicator led may not be tied to GROUND unless it is doing it thru the MAX1811 IC.  What should the normal operation look like for this circuit?  When should the led be lit or not lit?  I believe the indicator led should be lit when the battery gets plugged in.  Then the led turn off when the battery if full.  How should it function?  Thanks.

When should the led be lit or not lit?  I'm curious if i wired up everything accordingly.  This is a 1 cell lipo battery charge circuit.
