Check batteries on DNA 250 vs DNA 200?

[mseabert]

I ran the battery analyser, using lg hg2's, on my dna 200 reuleaux and set that as my batteries discharge curve-all good. Tried using the same battery curve with same batteries in my new Boxer dna 250 triple 18650, but I am getting a check batteries message on the 250 with approximately 28% battery level remaining. This does not happen on the dna 200 if I swap out the same batteries into the 200 and swap the same tank onto the 200. Soft cutoff is identical on both mods. The other weird thing is the 200 is showing 18% battery remaining instead of 28%. The dna 200 will not give me the check batteries warning, even running them all the way down to much lower than 18%. What gives?

I would think/guess it is far more likely to be differences in the battery contacts or wiring than the boards, a but more voltage sag from a weak spring, small contact area, poor ground connection or skinny wire.

excellent suggestions VapingBad.  I'll probably run the analyser on the Boxer 250 and set that as the battery curve for the Boxer.  I'll update this post with the results as to any changes in the unwanted "check batteries" message.
