I use dry herb vapes that are called bakx from lamart. I have different ones and all work the same way. I switched them up on this mod but it doesn't work right. For example on a thelem solo dna100c they work without an issue. The dna 75c eris has something inside ( a big resistance?, that's why the cold resistance is mucher higher than it should be from the "atty" alone?) and this created the heat.. This is my theory after observation but I have no idea how this could happen.. Do you understand the problem? Because I have to describe it to the place I purchased it too.. Or is it with that information still unsure if it's the mod itself that causes the issue?

Like this? I set the power at 20 Watts with temperature control, but the temperature control doesn't work so it just goes full power the whole time. The board temperature was going up even at this low power?

Hello guys! I bought once again a new mod, a viscious ant eris dna 75c 18650 version 😃 I heard this mods have good quality.. The cold resistance reading was very weird from the start, it was reading 0.34 ohm instead of 0.24 as on two other mods for this build. I still tried to use it, and the mod got very very hot in a short time. Kinda like a short? I turned it off and took the battery out, which was only warm. I never had this behaviour before. I would say the heat source was internal on the board side and more at the top part, where the 510 connector is. Is this a known issue? Also the resistance reading was going down while firing instead of going up as on the other two mods. Like usually the cold resistance is 0.24 and when I fire and reach the desired temp it's about 0.27-0.28 but with this mod it started at 0.34 and was goind down to like 0.31. Very weird for me. I couldn't find something with a fast search. I thought I ask first here before I contact the shop where I ordered it.. Thanks in advance for any help!!

btw do you know which one is the board temperature thermistor? or are there more thermistor for temperature measurement?

Thank you for checking! For me it looks kind of similar to mine..

240516_bakx_setting_rebel.ecig No I'm not a nicotine vapor or have any coil for liquid vaping.. Yes I bought the mod new from a store, which I think works together with the manufacturer I believe. I have this mod since january and this problem occured very few times in the colder months but it occured when used a bit heavier. Now since it's hotter temperatures it overheats faster. With my other dna100c mods the board temperature never surpassed 50°C with a much stronger power demand. (Just for comparison)

This board looks different than the one from dna 100c? It has only one of this inductors. And the one get's really warm. Does anyone know where is the temperature sensor for the error: "chip too hot"?

Sorry the colors are a bit misleading in the chart. The power is light blue and the temperature of the heater is darker blue. It has never over 70 watts ( very short time) and then only around 20 watts over the time. I think this is a expected power over such a timeframe from a dna100c mod? edit: left y-axis in the chart is power for the light blue data. right y-axis is temperature for the red and dark blue data.

No not exactly. The other two that work good have a metal enclosure and a little more space. Models are lostvape thelema solo dna100c and hadron mini dna100c. The one with the heat problems is 3d printed plastic from rebelvape.

Thank you for the answers! Sorry the colors are a bit misleading in the chart. The power is light blue and the temperature of the heater is darker blue.

Hello my friends, I use a mod with the dna 100c chip connected with a 510 extension cable which is connected to a heater. The resistance of the cable is 0.015 ohm and the resistance of the heater is 0.210 ohm. After less than 5 minutes of use the mod gets the error "chip too hot". Because the temperature of the board (red data in chart) is over 80°C. But there is no heat source near of the mod. The cable is cold, the battery is cold. The heater is hot as visible in chart (dark blue) with temperature set at 230 °C but the heater is far away from the mod. The extension cable length is 60cm. There at the lighning symbol was the error chip too hot. What is the problem with this board? Is there something defect? I have other dna 100c mods that have no problem with the board temperature with the exact same setup.. In the diagram is a heating session first with a pre heat and than continous session with under 20 Watts after the temperature is reached. But even with this "low" power the board heats up over time. I'm very thankful for help!! I can also provide more information if needed
