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.
They reccomended LG HG2 which are the same as Sony VTC6.
“You will need raised cells but not button tops. The button tops will not fit the light properly. It will still power on but it will not be waterproofed because the battery compartment will be open. I suggest LG HG2 or any style of battery that will work in series.”
