Can't reach the wattage

[Kisotama]

Hi guys,

So I've been stuck in this situation for about 2 week and still found no answer
Every time I use a 0.15 coil always fire at around 40w ( I set at 65w ) for no reason and I'm using wattage mode, I've search on gg and found that some said because of the tc mode but I don't see any tc in watt mode (lol) how do I fix this ?
btw I don't think this problem from the battery because I use cylad 18650 40A on both z100c & sx mini mx class, the sx can fire up to 80w while the geekvape z100c can fire around 40w
device : geekvape z100c 
tank : wotofo profile m rta with adapter

Either the cell can't supply enough amps (has Mooch tested the Cylad 18650 40A for 40A?) or you have battery connection problems.

I notice that if the board in diagnostics not going to 40 degree or further , the device has no issues with wattage drop , idk what happened to my device but it sound like tc mode despite I'm using wattage mode

Hoover your mouse over the area indicated by red arrow. That is the voltage drop on your cell when firing. Report back to us what that voltage is.

[Kisotama]

3.4v but when the board up to 40 degree the volt drop to 2.4

[BillW50]

Yup, battery voltage is too low and the mod drops the wattage to compensate.

[dwcraig1]

So if your able to get 80 watts out of your other mod with that cell then it is most likely a poor connection between the battery and it's contacts.

That cell is at best a 20 amp cell but should do more than 40 watts.

I tried a brand new samsung 40T 21700 and it's fixed but when the device feel a little bit warm it's starting drop wattage again , idk why it drop wattage every time the device hotter

[Kisotama]

Anyways how can I change the temp protect on this mod , I thinks it's start from here

[dwcraig1]

The wire type needs to be something other than kanthal or nichrome and be in a profile for temp wire for temp vaping to be activated. Use the appropriate profile. Example Watts profile with Watts selected for material, no temperature control there.

Does your voltage drop change a lot after it get warm? Where does the heat appear to come from? 

[Kisotama]

It's come from the mod , I checked the board when the wattage start to drop and it's above 40 degree

[dwcraig1]

 

Here's mine firing at 65 watts

[dwcraig1]

Your voltage drop should be very close to mine, perhaps a bit less with your 21700.

[Kisotama]

what battery did you use ?

 

[dwcraig1]

It is a Samsung 20S 18650, a true 30 amp cell. 2000 mah

[Kisotama]

alright tks , I will try it

[dwcraig1]

A Samsung 40T is a 30 amp 4000 mah cell, the perfect choice for your mod. The Samsung 30T is another good choice, 35 amps and 3000 mah.

[Kisotama]

hmm can a 3000 mah can last for a day ?

80 watts all day on a single battery is a tall order. 🤔
The best way to estimate would be to use this. Put in your battery specs.
