Segelei Z Max spring

[evilboltneck]

Hi folks. I was just wondering about the spring on my Z Max. I've got an Aga T2 rebuildable sat on it at the moment (finally got the coil working properly! Absolutely rocking my banana caramel diy mix yay!) but I've noticed the device is getting warm when I fire it. I've got a UDT-L mod for work and bought a silver bullet hot spring to replace the stock spring, but I also bought another spring as a spare.
Has anyone replaced the stock spring on a Z Max and if so, is it a good thing to do or does it make no difference?
Any advice would be greatly appreciated

I really don't think it will make any difference changing it out unless you use the wrong spring. RBAs tend to get pretty hot so the heat could be transferring to the battery tube and has nothing to do with the battery or tube.

Well, you could replace the hot spring with others in turn, and see if one of them doesn't get hot?

Short version: if it gets a bit hot, there is no reason to worry, unless you're using a cheap battery.

Long version: if a spring is getting hot it shows it has some resistance. It's working a bit like a fuse - if too much current goes through it, it blows (or in the case of a hot spring, the metal goes soft and it collapses). To test the resistance of a hot spring, you have to use a sensitive meter with two decimal places after the decimal point, with zeroed-out probes, otherwise you can't see the resistance as it is too low, typically less than 0.1 ohm. If a hot spring measures over 0.1 ohm then it will get hot. This isn't necessarily a bad thing although you will be losing voltage at the atty.

You could pull the spring out to check the one in there (I use some stiff wire like a coathanger, cut about 10" long, with a small hook on one end made with pliers). Or, insert a dummy battery, then test at the atomizer connector when the switch is pressed, and you can get the entire circuit resistance including the switch/actuator. You can make a dummy battery by using some wood dowel cut to the right length, well-wrapped in kitchen foil, then covered in insulating tape except at the ends.

Another test you can do is measure a battery's voltage, then insert it into the device, then test the voltage at the atty connector. If you are losing more than 0.1 volt, or if the hot spring has a resistance over 0.1 ohm, then you will be losing power. If a hot spring has a high resistance, then it will get hotter, you will lose more power at the atty connector (due to voltage drop), and the hot spring is more likely to collapse especially if using a sub-ohm coil on an rba.

But like many things in ecigs, if it works OK then there is no need to worry - if it vapes OK as far as you are concerned, but the spring gets a bit hot, then it's not really a problem. You do need to worry if you're using a cheap battery though, because it means you are pushing a lot of amps (for these tiny cells). Like any APV you need gas vents in it, if for no other reason than to give you an early warning. Gas vents need to be at the top of the tube, they may not work if they are at the bottom end. The pressure is much more likely to rise at the top end if there is some kind of a problem.
