Here's my question, will it light up the screen by USB power only.....just curious?

When one of mine was doing that it was because I had juice trapped between the balance connector and board.

Best I can tell, just checked a few of mine, is that it still doesn't function properly. EScribe 1.2 SP5.2 on my computer has firmware for 200/250 dated 12-22-2016. Still shows "?"

Have you tried rebooting the device? Either by removing battery or through Escribe?

16.65 watt hours with soft cell cutoff of 3.09 volts and the latest recommended firmware should get you back in order. Battery type: Lithium Polymer, 3 cell

Yes you can flash to older firmware. If it's not within your Escribe you may have to install an older version of Escribe to get the older firmware. I'm not thinking it will change anything charging wise but can't hurt to try.

The maximum charge (amperage) with a 200 connected with a data path shouldn't exceed 0.5 amps. Something wrong with the board in my opinion.

Rotating the cells of the pack when in a series serves no purpose like it would if they were in a parallel, if they work best in a particular order you might consider installing them that way every time.

If you feel like affixing a jumper wire from the output and ground for the 510 on the board and use atomizer analyzer in Escribe that will narrow down to whether it's a problem with the board or not. Kind of extreme perhaps but effective.

Well I think I missed part of your post, how about how well the body of the 510 grounds to the case....any oxidation?

check the 3 screws holding the board in the case to make sure they are not loose, that's the ground for the 510.

First 3 2500' in parallel, 2nd 3 2500's in series

It would pertain to all cell types. To be more clear perhaps, two (same) cells whether connected in a series or parallel would have the same watt hours when paired. https://milliamps-watts.appspot.com/

Tell us more please, what was it?

Example:

Escribe will show what the voltage of the cells are under load. It sounds as if the board is not getting good power. Might be the batteries, might be bad connection(ect.) of battery contacts to battery. Might be bad solder joint somewhere between batteries and board.

The curve only makes the battery gauge more accurate, it doesn't change battery performance

Have you tried logging off then back on?

Where you bought it if new, Lost Vape service center or a ticket with Evolv. 4.2 volts is full charge for most Li-on cells, there are some that are 4.35 volts.

See that cell #2 reading 5.05 volts, the board is the problem.

Bridge ground to B -, bridge 3 to B + to eliminate using wires. That leaves 1 & 2. Starting from left 3 (red),2,1, gnd.

Maybe uninstall and re-install Escribe, might try a different cable too.

LOL, comes out the same.
