Sorry I forgot to quote who I was replying too, it is the 1st one of this post, all the way to the beginning, sorry again.
Yes, with the VT133 it has 2 metal square boxes soldered on the side
of fuses they are the biggest square metal looking boxes on the
board. They are silver and maybe rusty color. 1 is 1/3 of the way up
the board, on the right, looking at the board horizontally and the 2nd
1 is approx. 1/3 of the way down from the left, they are almost the width
of the board on the edge you can read DNA 200 and on the other side
opposite it says EVOLV.
From me dropping it so much the one closest to the fuses and right next to the two square black chips that are soldered 1 above the other on the left side of the board fell off (I could hear it hitting around, so I just took it out and kept using the mod) but it still worked but when I got the same message you got about the battery (some time much later) I opened the mod again and saw that the other one was about to fall off but it was still soldered so I just placed a folded up cardboard till it was flattened down on the board. I did not know how they are soldered down but it looks like right in the middle of the square.
They should have placed some hard foam or plastic be hide them and the frame of the mod, but that took care of my problem and I sub ohm at 0.2ohm and no more than 70 watts, more between 48-58 watts.
I hope this helps,
