azd2 Posted August 15, 2015 Author Report Share Posted August 15, 2015 Hi,after succesfully building annother Mod with a DNA 200 i tried to run the battery analyzer because i hoped to get better settings for my battery than from what's printed on the lipo.I built a HUGE coil , put the whole thing in front of a fan and let it fire with 60w by the battery analyzer.After draining roundabout half of the battery (it was after ca. 30 mins), Escribe suddenly hung and didn't do anything anymore.I restarted the software, but it couldn't connect to the mod.I tried all sort of things (updating the firmware just resulted in annother "not connected" message), but EScribe didn't recognize the mod anymore (other DNA200 chips work).The screen stays dark, whatever i do.The board gets really hot when i connect either USB or the Lipo, but nothing else happens.There were no problems at all while vaping normally before.Firmware used: Version from "2015-08-07 EScribe" What happened to the board, is there a way to revive it?

protovapor Posted August 17, 2015 Report Share Posted August 17, 2015 Keep trying to force firmware updates, have heard of someone having to do it 3x to get it to "take" Link to comment Share on other sites More sharing options...
azd2 Posted August 17, 2015 Author Report Share Posted August 17, 2015 Already tried that.Nothing happens, only a great amount of heat developed from the marked chip (the chips where the coating partly melted away get hot too, but this chip seems to be the hottest): The Pc doesn't even recognise a new device beeing connected.

Willy Posted August 18, 2015 Report Share Posted August 18, 2015 Took me a bit to find what chip you marked so I added a yellow arrow pointing it out. What's is that at the lower left mount pad where I put the blue box? Link to comment Share on other sites More sharing options...
Willy Posted August 18, 2015 Report Share Posted August 18, 2015 Forgot to add, can you post a pic of the other side of the board including the fuse? Link to comment Share on other sites More sharing options...
Peter7734 Posted August 18, 2015 Report Share Posted August 18, 2015 Looks like an alligator clip with insulation holding the board Link to comment Share on other sites More sharing options...

Dragon Posted August 18, 2015 Report Share Posted August 18, 2015 I wouldnt expect the board would be able to handle this type of continuous loading abuse....my computer battery analyzer has a big ole heatsink and fan for a reason ... Link to comment Share on other sites More sharing options...
azd2 Posted August 18, 2015 Author Report Share Posted August 18, 2015 Well, the design of the function is well thought through i believe.It didn't fire the chip countinously, but fired for a certain time (not sure how long it was) with the configured 60w, waited until the voltage of the battery got steady again, fired again and so on, plenty of time to cool down i'd think.I think that i might have the same problem that these other threads are about (Chip suddenly dead while vaping, getting really hot when connecting USB...)https://forum.evolvapor.com/topic/68312-topic/?do=findComment&comment=914351https://forum.evolvapor.com/topic/68313-topic/?do=findComment&comment=914354https://forum.evolvapor.com/topic/68203-topic/?do=findComment&comment=913319Sadly in some cases a FW-Update seemed to work, in mine it didn't Link to comment Share on other sites More sharing options...
Dragon Posted August 20, 2015 Report Share Posted August 20, 2015 I got the impression it was fairly continuous or at least a lot heavier then typical vaping use (i.e. 1/2 the battery in 30 mins)...Im thinking the on board battery data is as a course of typical use, not really designed to work as continuous (more less) drain analyzer..perhaps something like west mountain radio's computerized battery analyzer (or similar) might work better if you need to test batteries quickly Link to comment Share on other sites More sharing options...
James Posted August 25, 2015 Report Share Posted August 25, 2015 The board should be totally fine doing Battery Analyzer.IIRC we did the stock curves using a LiPo at 50W, using resistor blocks and no fan.The Board Temperature sensor will protect well before the board should have any problems, and even at high powers it takes a while to get that hot. I admit I've not tested with a fan present, but I can't see that making a difference unless the Board Temperature sensor was being cooled by the fan better than the rest of the board... What power were you doing the test at?Hmm.Send Help Desk a ticket for a replacement, and have them send the board to us to take a look at. We'll see what we can see.Thanks!James Link to comment Share on other sites More sharing options...
azd2 Posted August 25, 2015 Author Report Share Posted August 25, 2015 The ticket is already closed with a request to send the board back for further inspection.Might take a while since i live in Germany...I ran the test with a power of 60 watts.

James Posted August 27, 2015 Report Share Posted August 27, 2015 Mm. Are they cross-shipping you a new one?60 watts should work fine. The board can handle it. Link to comment Share on other sites More sharing options...
