Ok so I had the same problem as another guy saying he tried to charge his lipo batteries and he gets the 4 red blinking light error message that means his batteries are discharged to too low of a voltage and the EZ charger won't charge it. After reading some of the solutions and comments left below that thread, I am still not sure if there is anything I can do to save the two batteries. They are the Lip 7600's. All the answers/solutions were totally above my head. I am an absolute newbie when it comes to this but I am finding myself wanting to learn more and it has become quite addictive tinkering with these things. Thanks for any help in advance. I didn't realize you had to put them in storage mode after every use if you weren't planning on using them and I think I am probably going to have to bite the bullet and order two new batteries...lesson learned.
