Hi Kuhndog, I am still a n00b with my Blade CX2; however, according to the instructions I have both lights blinking mean you over discharged the battery. They suggest trying to charge it a few times and see if it clears itself up. But, to be honest, that sounded like BS. I would say it's time to purchase a new battery and learn from your mistake of overuse. I guess it's also possible that the battery may be dead - most other users on here seem to get between 50-75 charges before they die though.

Again.. i'm just going by what I've read here.

Good luck!
