Remote control bb talkin 2 takuma efoil trouble

Hi all
I received yesterday my takuma efoil
First day and rode one battery all fine.
Today I went to pair again and noticed remote was showing as battery empty, tried to pair but couldn’t and did the steps over and over again. Remote started vibrating and wasn’t stoping and after that went dead.
It’s on the charger since some hours, blue light is on but controller won’t start or reset
Any ideas?
Thnx!
