I just took batteries out of the MT03II 70.2 and found out the 2batteries were at 4.2V still full but other 2 were at 3.90V. Haikelite should look into the problem right away and I think most of the first badge are defected.
The 2 emitters were blinking like disco light since the first time I turned it on and I have already E-mail Haikelite about the problem. They promised me that they would give me a good solution but I have been waiting for about a month now and still no solution LOL. Now new problem.
