I had a DNA 200 built in a Hammond box dual 18650 in series. The question I have is when I go to use it it will only ramp up to 50w at max, even when adjusted higher. Anyone ran into this? Any help is appreciated! Using lg hg2 batteries.

Here's an example of where I would start looking.
In EScribe/Device Monitor tick the two cells and not what the voltage sag is. My batteries in this example were 3.68 unloaded and when fired drop to near the soft cell cutoff. Had they dropped below the set soft cell cut off the power would have dropped.
Here's my example:

Also, you might want to check the 'Kanthal Power Limit' on the 'Mod' tab in Escribe...

These are my settings. Should the capacity be changed? I've tried everything I know but can't get it to work.

The only setting on that page that can have anything to do with your problem is set correctly to 133 watts.
We need to see it firing in Device Monitor with the two cell ticked. Use the stop button in the right lower corner once you get it then move your mouse over the sagged voltage points to show the voltages (if not showing)

Looks like one battery is hitting your 'cell soft cutoff' setting. Are you seeing a 'check battery' message on your screen? I too run 2 LG HG2's & have my cell soft cutoff set at 2.8

No check battery but the battery bar did flash once. And my cut off is set to 3.09.

Oh yeah...they changed the message to a flashing battery symbol...lower your cell soft cutoff to 2.8 or 2.9 & give it a try...
