I have five Lost Vape Therion 75c, and one Mirage mod. They all use the Evolv DNA75C board. I never had any sort of problem with those mods, and I use them quite extensively. This to say, I believe the failures you experienced, are likely to be caused by a factor external to the board. Humid or salt-water environment, excessive temperature swings, excessive electrostatic charge (carpets), excessive RF fields, and many more could be the cause of your multiple failure. Once you are 100% sure that there are no external causes of failure, only then, consider you have come across three defective DNA75C boards.

I would like to add my experience with "Temp protect" error. It happens more often when the wick of my RTA (mostly Berserker and Ammit MTL) is too stuffed and prone to dry hits when in power mode. There is no error until the wick is saturated. When the wick dry out, the device applies too much power for the diminished wetness, and it stops with the error. Then I diminish the max power, and the device seems to retrain on the new power-temperature relationship. In any case, I can stop the "Temp protect" error by simply releasing vacuum in the tank, unscrewing the fill cap. But, it is the wrong way to vape. When I build to avoid dry hits in power mode, and conseguently "Temp protect" errors in TC mode, the tank will leak in few hours or few days at best. Especially when you change e-liquid composition. Hope this helps,

I had this issue with the Therion, battery percentage showing 98 percent at end of charge. I suspected something with too thin wires from the battery cradle to the board, or some other reasons for that voltage drop - amounting at the end, to few milli Volts. My solution has been very simple, a workaround I would say. In the battery curve, I brought down the 100% point to 4.16 Volt, and the 90% to 4.03. It doesn't affect the true charge endpoint, just the percentage monitor. And it works wonder!
