    Just For LM2596 Users

    so for 12V IN use 330K, for 8.4V use 220K...You can use smd resistor as well, you don`t need power resistor, because cross only 10mA maximum from + to pin5

    the advantage of use power on with pin5 is : you don`t need a 3A switch, you can use a mini sw, will cross only 10mA.

    what is this topic anyway? it`s to increase number of posts? or what? :D

    PTN04050 Booster, need help! (Since i succed with the PTR08100 next...)

    and link BOURNS|MF-MSMF200-2|MULTIFUSE, SMD, 1812, 2A | Farnell România for example, must buy for 3A 4 A 5 A and test to find something good for ptn04050C

    yep flat ptc fuse, because @bohoo is from my country i will tell in our language, whit your permission off course :), ....se numeste siguranta resetabila....you find this at Farnell.com

    you may use NC contact or NO contact.Ideea is to have 1 logic on pin 5 for off, and 0 logic for on.Works great like in schematic.

    if you put a diode to IN protect board of revers polarity only :), diode in a circuit is not for higher current protection :), use a reset fuse for protection

    Use a step down with 2xbatt, is the best way for VV.

    First Mod Attempt.... couple of questions.

    to make series connected from that box: cut 1 coil and solder to a single + plate from middle of box, and you have series connected batts

    Using a multi voltage DC adaptor?

    :D maybe it`s good to use at home a 5A power supply :D

    works with 100k to 330K, it`s not fixed.that schematic was made by me anyway :D. With 220K it`s ok.

    so between adj, out+ and GND you have a resistor divider for adjusting the voltage. It`s recuired both resistor, but one of this may be trimeror potentiometer for adjusting voltage :) also PTN04050C don`t have short circuit protection..

    maybe will be better if you make that PCB custom, home made after schematic. :D

    Just For LM2596 Users

    On lm2596 you have pin 5 on/off pin.If you able to modify that PCB, and put 220K pull up resistor from pin 5 to + (off mod), you may use a small switch to pull down to GND that pin (on mod) like picture:

    First Mod - a V/V

    A day 14500 TF:blink:, 7 hours for me that kind of batts.I vappe 4-5ml per day

    lavatube and battery proplem from ecigwizard

    maybe you must learn to use a VV mod.Try to vappe not to high voltage, you damage that atty or carto if not set voltage correct.

    First Mod - a V/V

    i can`t answer of your question.you may use mp2307 module, it`s much better, have great efficiency. Will slap me @tomcatt but this is the true, mp2307 beat lm2596 :D

    First mod: The Dupblow

    great but it`s good if you can cover that batts :D

    First Mod - a V/V

    yep lm2596 it`s a good IC for what we need :D
