Replacing my Mosfet (fried)

Im not sure what you started out with but the Diagram for the Parrallel build is correct, you should be able to measure your voltage at the 510 or better still accross your coil to see whats been delivered to it. You will have a voltage drop, but without spending a lot of time looking into it I cant say more, I know plenty of people are using the 3034, so it must be working ok.

**Updated**

Your correct on your diagram, one battery is swithing the Mosfet, the other is powering the 510. Stick with the other diagram. Sorry I cant be more helpful, but I have something agravaiting my eyes at the moment.

 

You are very helpuf already, thanks a lot.

You say my diagram is correct but stick to the other one ? I don't get it.

Mine is obviously underpowering (the battery connected to gate is still full charged no matter how long I vape) so I want to try the one from internet. Would you think it is safe ?

Using a whole battery for the gate means i use only one to fire, that seems a waste for a dual paralal box.

Again, your knowledge is very precious to me so thanks again for taking that tome to help me.

 

I should have said your evaluation of your diagram is correct, you are using one battery to power the mosfet and one to power the 510. It also means that you are taking all your current out of the single battery, not a good idea. Stick to the one from the internet where the batterys are parallell.

 

Got it, big thanks!

 

ohh my. i miss all you guys.. i had a lot of eork over the last months and thr company that i am working with was sold. so a horrible nightmare at the moment.

have not gone trough all but a call for help was in the mail.

so 1st boxes from china have not the reliable mosfet. as you have noticed.
needs changing.
then i saw why is the 1 and 2 battery power.

all is down to the internar resistance of all wireing and batteries.
as you know batteries have also an internal resistance. the lower or higher the overall resistace the less the voltage drop to the atty.
if you have 2 or 3 batteries then the resistance is halved or devided by 3 meaning less overall voltage drop to the atty. means also more power by then.
same goes with the mosfet. it has an amp limit, means you can only go down to .2ohms about, to go down lower safer means adding a mosfet parralel to it.

hope that liggtens somethoughts.
when i have time i will chevk to the forum again as i have been playing with a new home made toy.
