It is strange, it should stop once the cells are full, it's a long shot but you could try and lower the Watt hours setting and the charge screen brightness to 0%. It maybe something the computer USB port is doing like cutting the power when the current get low preventing the last 1% of charge all I can do is guess as I have not had any problems. Another thing that is worth a try is connecting it via a USB hub with something always draws power also attached, or an powered USB hub.

The pins on the balance connector could be dirty preventing a good reading or you could have a weak cell, what are the cell voltages?

You probably need to remove the .txt extension, you may need to uncheck hide know files extensions in Options in Windows Explorer first to do this.

I think we have all been there, well I have anyway it got me the first time.

It maybe something your USB is doing preventing it going onto idle, they only show in idle try a USB power supply if you haven't already done so.

They are fine, I am using one, think of them as a reasonable value brand (the main brendon hoibbyking.com), as for the best brands IDK maybe an RC hobby site is a good place to look, if you are in the US and price is no prob Max Amps have a good range.

Yes it is up to spec, the make is OK, but they do have to occasional misswired one, it is on the big side but they all will be if you want that capacity/

I doubt StealthVape get their wire from those cowboys, they have been in the game much longer and actually know a lot about vaping.

20C is the rate, 20 X the capacity = 20 X 2.2 = 44 A

OK it's the bezel/lens, do you have enough clearance for the screen cable as it sits a bit higher?

Yes, conceptually the DNA tells the PC that it would like up to an Amp then the PC should provide the closest it can't get, later versions of Windows do not have the power setting on the USB driver so provide only 0.5 A. I am no expert, but there a few methods for USB devices to tell the host what current they require and Apple have added non standard ones into the mix. If I feed my DNA200 with a 5 V 1.7 A supply they never draw more than an Amp, but a dirty supply may damage the the DNA and cause this to be exceeded. E: The simplest method of requesting more current used by many charging cables is to short the data lines & IIRC ther is a variant with a resistor across the data lines that requests a specific max current. A largest concern with USB supplies is a power spike on the mains earth which is normally used for 0 V, these are caused by lots of conmen appliances like refrigerators and should be filtered out by the USB supply.

There is a photo of them side by side here the spacing looks a little different and the screen is bigger. https://www.e-cigarette-forum.com/forum/threads/the-reuleaux-by-jaybo-designs.707444/page-23#post-16983648

I really don't understand what you mean Jacquith' I am trying to help you, the charger mainly works in series not on a cell by cell basis. The charge current across all 3 cells for most of the charge cycle is via the thick wires and the same for each cell, the balance taps are only used to monitor the cell voltages and drain high cells when balancing and never for charging, they do not carry over 40 mA.

You can get a really good mod resistance measurement with a modified cartomiser, almost as good with a solid copper bar (brass & aluminium should also be good), have a look in this thread http://evolvapor.forumchitchat.com/post/mod-resistance-7522239. I have the right thread die and haven't bothered as I doubt I will get a better reading than the carto one.

Not got a Lavabox but both my DNA200 the cable is secure enough the support the weight of the mod. Looking a the plugs there are 2 sprung locking lugs on the underside and maybe they are weak on your cable.

Who the said it did? What?? USB with type D connector has a 5V limit. Evolv limits the voltage to the Cell's capacity not the series voltage; balanced charger...[/QUOTE] I thought you did "The stock Evolv USB charger on the DNA 200 is 1A and it will indeed supply the full 1A to the balancer" But I confess I am not sure what you mean by the balancer as it balances by taking current from the high cells. But the the charger can not supply 1 A because the board only get a max 5 W from the USB and the min charge voltage being about 9 V the max current would be about 555 mA if it were 100% efficient voltage conversion.

Yea yours is really only on the preheat and not just one channel Chunky.

The 1 A refers to USB current not the current to the battery, it can not supply 1 A at 9 - 12.6 V to the charge chip from a 1 A 5 V supply,

The output is limited to 50 A & 9 V, you can see the graphical ohm vs power diagrams on pg 4 of the datasheet.

USB charge only cables are becoming more an more common, I know you have tried a few but if you can confirm they are data cables with something else that uses data one Micro USB it would be a good idea.

Don't recovery charge if the batteries are charged externally. It sounds like a problem with the balance tap wiring, they took a couple of short-cuts wiring these which may explain why cell 1 is low, but I don't know who cell 2 could be 5.15 V. A few people see cell 1 consistently low here /topic/67176-topic/

It only has 2 balance wires, number 1 & 2, GND & 3 are jumpers from the battery connection pads, but the negative battery connection goes via the ground tab to the top left ground point on the board and the positive is wired. So as I said above there is a possibility the GND balance connection is higher resistance and why I asked if it is common that cell1 is the low one.[/QUOTE] Sorry Vaping, i'm not so "technical", does it mean that i have to send it back (if Wismec reply me) or i can do something to fix it by myself?[/QUOTE] IDK, there seems to be a patten, but only a few people have reported it so far although it is always cell 1. I think it will only effect the battery monitoring under load which may cause the DNA to go into weak battery earlier the otherwise and not the vape. You could check the ground strap connection, but the screw hole is covered with a white plug and removing it would probably void your warranty. I am waiting for one to be delivered and will have a closer look at the issue then.

Lots of us here are running 1.0.35.2 from /topic/66731-topic/ , but it has not been put in the auto update chain, I don't know why.

The ground strap I was speculating about is shown in the 1st pic in this post.
