small problem with my new lipo

[_paralyzed_]

the last bit of charging just takes more time with larger batteries. You are balancing 6 cells now instead of 2. Cells that are too high have to be discharged. I'm willing to bet if you just let it go it would eventually finish the charge, it just slows down a lot at the end because of balancing. The fact that it worked with the blinky further leads me to believe this. You're assuming you are smarter than the charger and shutting it off before its done. Just let it go. An out of balance pack could take upwards of two hours for a complete balance charge, while thats unlikely, you have a new pack that needs to be balanced and conditioned, let the charger do its thing.
