Removed the chip, cleaned the pads of the board and of the chip, added solder paste to the board, placed chip, heated up and voilá, the chip moved itself to its own place. But it did not work. Now I am getting 0 in one cell and 4.18V in another lol Gonna get another board next month, hurts me knowing one of my devices is dead even if I am not using it. Thanks you all that tried to help!

@BillW50 Thanks for the encouragement, I will try that. My experience with the hot air station is limited and I've used just twice (successfully) to replace a lvds chip of a laptop that I have, but the lvds is twice as bigger as the BQ76925. I am going to try anyway, worse case scenario I will get another board for 45GBP. I will report back!

@BillW50 Thanks for the suggestion, I even had a glimpse of hope thinking "this is so simple, could be that" killed instantly by "I've done the soldering twice, and in the second time I really reinforced all points, and tested".. But I tried and no luck, all readings are fine. If the BQ76925 was not so small and with so many pins, I would try to replace myself as I have a hot air station. Let's see, gonna try Evolv, or just take the board from a Triade I have around and I don't use it. Thanks for the help!

@BillW50 I've done the bridge test before with the ohm meter and it reads zero, so the wiring was fine. Even though, I've bridged them but the issue persists. I've checked the software part, making sure two cells are set but I don't know what else to do. Maybe this little fall affected the board in some way that I can not fix myself. @dwcraig1 Tried that, no dice. That's what I get when checking the device monitor, Thank you both for answering the thread.

Hi all, I would like some help before contacting evolv. I've been using a dna250 (it had a dna200 and I replaced for a dna250, I don't remember the reason) with a starss player mode 2x18650 for few years already and no issues. This week I've dropped it from the bed side, that is, 40cm max, and in to the carpet. Turns out that after that the mod is dead. It only register one battery like in this thread, and the wiring is the same - https://forum.evolvapor.com/topic/70400-dna200-2-x-18650-not-registering-cell-1/ I did all the wiring again, cleaned contacts, lots of flux, wired it all again, and the issue persists, fuse is fine, continuity is fine, make sure the ground with the box is fine, but nothing is helping. Please disregard the amount of solder in the battery sled, Back of the board - you might say the solder of the b+ is doggy, but that is reflex, I've double checked now after looking at the picture. There's a whole blob of solder in there and the wire is making nice contact https://i.imgur.com/jEb3tyJ.jpg battery sled wiring https://i.imgur.com/60ZMPjf.jpg front of the board https://i.imgur.com/Rthco0c.jpg wiring https://forum.evolvapor.com/applications/core/interface/file/index.php?file=/monthly_2018_10/Dual_Series_18650_DNA_200_250_Box_Mod.thumb.jpg.2742da6e14aa04f0eb2157dc52404524.jpg I remember in the past, when I bought two broken triades and they had the same issue, only displaying something when holding the fire button. In both cases I bridged both pin1 with -b and pin4 with b4 like this https://i.imgur.com/4NM9btD.png and both are working fine for around four years - altough I belive I've read this is not recommended. Any ideas?

Sorry for the bump of a old topic, but I'm with the same "problem". After having one cell not being read, and without a multimeter around, my choice was removing those two "black blocks" (some research lead me to it), removed them, bridged B- to G and B+ to 3 and the device started to read my all 3 cells again. Thing is, can I use it without any problems, or should I replace them? Logic says, replace, cause they were there for a reason. In that case, what are them, and what spec? Also, as I moved from south america to UK, I left all my stuff there. Can anyone recommend me a multimeters to deal sometimes with small components that we got in the dna boards? I'm just an enthusiast, that sometimes buy a DNA second hand and gives a nice clean on it when necessary. Would this do the job? https://www.amazon.co.uk/Multimeter-Tacklife-DM01M-Temperature-Resistance/dp/B01N3RVVJ4/ref=sr_1_2_sspa?ie=UTF8&qid=1524316324&sr=8-2-spons&keywords=multimeter&psc=1&smid=A7AX9JMU6J7L7

Trial and error, but it's done! Just did same wiring as a dna reuleaux I got here, and all good!

Hi all! I've got a situation here. Recently my Triade decided to not work anymore. Cells inside, it only turns the screen on while the fire is pressed, other than that nothing work. Connects to escribe normally. Also, I`ve got a Starss Player Mod (2 cell) DNA 200, which I don`t use much cause 2 cells dont perform well. So, as 2 cell is not my cup of tea, can I remove the dna200 board from the Starss, and use it on the Triade? Looking only thru the side of the wires, seems to be straight forward, but I might be wrong. Any advice? Here are some pics, Triade, https://imgur.com/Y7YSi7T https://imgur.com/FZ4ZtY5 Starss, https://imgur.com/FTi78Ca Any help would be much appreciated!

To make your own profile, just run battery analyzer yourself, and get your proper discharge profile for your batteries.. About cell cutoff, 3.2V is fine, you can try lower but won't get much difference..

You're welcome! Remember (it's not a rule), spaced coils work better in TC mode than contact coils, at least, to me!

If is SS316L or SS316 you can use one of the attached files.. DNA200-SS_316L _Elite-SteamEngine.csv DNA200-SS_316-SteamEngine.csv

Follows attached .zip file that contains .po file for Brazilian Portuguese translation. Also can be user for Portuguese from Portugal. PT-BR.zip

But, why not? Been using ss316L Clapton coils, spaced, and TC works very well.

It would be the opposite, no? In parallel does not matter if is rotated or not, in series, matters..

Well, issue continues happening.. Not a problem, I was just curious about.. Thanks

Hi buds, all good? I'm facing some strange behaviors when I remove empty batteries and replace for 03 charged ones. Lets say, I have 02 sets of LG HG2 which are used only on the dna200. Right now I removed the almost empty set of "1, 2 and 3" and replaced with a new set, the "X, Y and Z". So, this time Z should be the 1st battery to be inserted, after Y, and last X. What happens? Nothing the mod did not start. Ok, pushed a little bit more, nothing. Removed all of them, replaced all in same order, nothing. Then again, removed all, swapped Z for Y, and last one inserted was X. The mod did start! But its time for the Z be the 1st one in the rotation, so I removed all again, and placed all as the same way when the mod did not start, and what happened? It started normally! I've noticed this behavior before, not only with the XYZ set but also with the 123 set. Seems lot odd to me, and 1st thought was, I have at least one defective battery, but device monitor shows normal volts for all of them in both sets, and also when I remove to charge in a external charger, they have basically same voltage, around 3.30V, and all of them finish charging almost at the same time. Also, I got same performance, around 400 puffs at 270 Celsius, 55w with preheat of 65 @ 0,5s with both sets. So,any ideas why this happens?

As a regulated mod, series or parallel would not make much difference. As in series the board will work with higher voltage and smaller amperage, and in a parallel configuration will work with a increased amperage and lower voltage. So, at end of the day, you are going to achieve same results, but just in a different way..

Many thanks for sharing this! Could I use this profile, or I should do one using mine VTC5 set of batteries?
