Jazzhead Posted October 25, 2018 Report Share Posted October 25, 2018 Hi guys, new (but experienced) member here. I was using my Lost Vape Triade DNA 250 today, and suddenly it stopped working. At first i doubted that my 1 year old VTC6 batteries (married since the first use). But then i tested them one by one in my Pulse 80W mod, all were working fine and they got at least %90 charge when my Triade failed. Tried my spare VTC6 set, they were no go too. Just disassembled whole mod right now and there are no solder disconnections anywhere, all solder joints are solid and steady. But the funny story starts after i hook my mod into my pc. Here's the screenshot i took from Escribe suite. Total voltage seems accurate, but per-battery reads are absolutely nonsense. Do anyone experienced something like this? I won't re-assemble my mod till i find a solution, so any opinions and recommendations are welcomed. Thanks... Link to comment Share on other sites More sharing options...
BillW50 Posted October 29, 2018 Report Share Posted October 29, 2018 Yes I have seen this on 3 DNA200 and 1 DNA75C so far and it appears to be a failed BMIC (Battery Management IC). After my DNA75C blew, I am leading on the belief all of mine blown when you disconnect the power and reconnect it back too fast. So now when I swap batteries, I wait at least a minute before inserting the charged cells. Link to comment Share on other sites More sharing options...

If it's not possible, i'll just buy a new DNA250 chip. Link to comment Share on other sites More sharing options...
BillW50 Posted October 29, 2018 Report Share Posted October 29, 2018 You have a BGA machine? Well yes, then you can probably replace the surface mounted chip. Link to comment Share on other sites More sharing options...

Actually no, but my friend has one and i can ask him for that. Now i just need to know which exact part that needs to be changed. Link to comment Share on other sites More sharing options...
BillW50 Posted October 29, 2018 Report Share Posted October 29, 2018 Not sure if the DNA250 uses the same as the DNA200, but it is a BQ76925. Link to comment Share on other sites More sharing options...
Jazzhead Posted October 29, 2018 Author Report Share Posted October 29, 2018 Thanks for the information sir. At least now i have an idea about what i'm gonna do. If the BQ76925 is not present in DNA250, it should probably be something similar and i know where can i find these modules. Link to comment Share on other sites More sharing options...
BillW50 Posted October 29, 2018 Report Share Posted October 29, 2018 (edited) That I do not know. But Google might show something. Hopefully not something that you need to order by the thousands. Edited October 29, 2018 by BillW50 Link to comment Share on other sites More sharing options...
