Heat affecting the way mods perform?

[JohnnyElsewhere]

I recently bought a really nice looking mod from Vapecore.com; it looks flawless. However .. I live in the desert .. where it's about 110+ degrees F consistently during the summer.

It was working fine when it was tested (for two days) before being sent to me; but it's very finicky. It fires for two or three seconds, then immediately dies. I can restart it, but it keeps doing that.

I was wondering, does weather affect soldering at all? Not that I'm saying that the quality of this mod is bad-- because it's absolutely solid. I love it! But .. it just doesn't seem to want to work for me consistently.

Any thoughts, ECF?

I'm not in the desert but I used various mods during the summer heat without problem. Sometimes I would set it down and the sun would heat it up to "very warm", still no problem (but not recommended ).

If it is a regulated 5 volt mod with a linear regulator then it may be tripping due to regulator temperature.
They have an upper temperature limit and a "degrees rise per watt". If the regulator heats up 50F that would be 130F at 80F ambient, but 160F at 110F ambient. That might be getting close to thermal shutdown.

LATE EDIT:

I looked at the mods they currently offer and can not tell which type of regulator they are using.
They advertise VV up to 8.4 volts (on fully charged batteries). An adjustable linear regulator won't go up to 8.4 volts with 8.4 volts in (it losses some).

It is possible that the atty/carto you are using is tripping the current limit on the cells or the current limit on the regulator.

What resistance atty/carto are you using and at what volts?

I'm using a LR atty from Liberty Flights at around 3.8v .. Sometimes I bump it up to 4v for that extra kick. The cartos I have are 2.0 ohm, and rock up to 4.5v.

That sounds reasonable. Maybe it is the "extra heat". Does the mod work indoors?

 

[JohnnyElsewhere]

I'm in an A/C'd house all the time, and it still does that. :\ I have no idea what to do, and it's already been repaired once.

 

[Rocketman]

Try it at a very low voltage (current to the atty will be less) and see if it dies. If it still does it then check the following:
Cell voltage under load.
Atty/carto resistance.
Your Li-ion cell may be shutting down (protection board) or the regulator cutting out.
Contact the vendor for help.

and promise you won't fuss at me for this,
you have a multimeter, right?

I have to wonder if there's a short that's tripping the battery's protection circuit. If so, pulling the bats and putting them back in will get it to start when it quits till it shorts again.

I'm a little late to answer this but maybe it might help someone else. I have a Splash from ShanB as well and a very specific carto i have (duel coil xl from madvapes) trips it as well. I have a ton of other carto's that work fine, so logically it would be something being tripped by that carto. I suggest getting another carto besides the ones you are using and testing it with that. Especially seeing as lr, and 2.0 are pretty close in Ohm (most lr i have see are around 1.7 give or take some), you might consider using a regular resistance atty or carto.

if the regultor is hot in the box it shuts down you can use a multimeter to check for a short somewhere in there, also I have had switch issues before on some of my mods I made. If the regulator is hot to touch try adding a heat sink on it to help cool it down if there aint one already

I have several mods and many of mine do that when my attys are older. The first couple weeks with a new atty, it doesn't happen. Once they are past the 2-3 week mark, I have to turn down the voltage on my variable volt mods because the ohms have dropped in the atty due to age. With mine, it's when they get below 2.0 that they trigger the shut off when my mod is set to 4-5 volts. If I turn my mod to 3.7 volts, they fire consistently then.

The ohms of my Joye 510 attys start at 2.4 ohms when brand new. Every week, the ohms drop a bit due to usage..
