My Maxi is starting to die. The past couple days it has been super finicky, and now its just acting nonsense. I put in a battery right off the charger (4.8nimh or my 3.7 Ultrafire 18650s) and it gets one great drag off of it and then acts like the battery dies. I took a look at the inside of the tube and it looks like the spring is bent somehow. My guess it is shorting out on me. Luckily I have my mini to tied me over, just wanted to get some advice from people before I pulled the trigger on a new tube or a SB.
