Wednesday Posted June 6, 2021 Report Share Posted June 6, 2021 I recently built a DNA250C using dual 20700s but as I run the battery analyzer the USB current keeps fluctuating up and down, without allowing the analyzer to start. I've tried making the max voltage of the batteries 4.17v to force it to start but that hasn't done anything. Is there any ideas about why this is happening? Could I have messed up some soldering at some point? Link to comment Share on other sites More sharing options...
