Just got this last night. I charged my VTC4's, brand new with the Reulaeux I got almost two weeks ago. On my Blu6, metered them at 4.2. Put them in the Reuleaux, battery percent and bar showed 84%. I have my charge fields set on this DNA 200 to display cell voltage. All were accurately reading 4.2, and it stopped charging internally. Watt hours were 18 something, in the device monitor, and I'm using a battery profile from here that the Reuleaux tested VTC4's at 21.44. That was still correct.
I tried swapping to another set of batteries, same thing, married set all read 4.2 in the device and escribe, but 84%. Was late so I just pulled the batteries and went to bed. Same crap this morning.
Then I put the batteries in rotated again, and got no screen, then error press up to continue. It booted all was fine, but 84% still. I ended up going into device monitor and changed my watt hours manually to 21.44, my pack was at 12.6, cells at 4.2. And uploaded, so far all is fine. I was gonna hard reboot, but I had batteries in, and it didn't seem to want to do it.
I'm gonna keep monitoring the cells. I set the charge display on this guy to show the cells so I could make sure all were staying balanced without escribe. Also, I should say that live monitoring, even prior to the fix, all my batteries sagged evenly dead on. .35 atty, kanthal, authentic vector, 63 watts. Everything but the watt hours, only in live monitoring was perfect.
So, I reset the watt hours when fully charged in device monitor. I've pulled and rotated the batteries since, we are good so far. After having to fix the screen ribbon a good week ago, now this, I'm concerned about this device. My Tugboat DNA 200 is over a month old, and it's been perfect. Hope this maybe helps someone.
