901 Passthru and manual battery hack

[Shaik Corso]

OK, so I ruined some (re: my only) batteries and had to get my 901 going somehow. So I made these......

I have heard some talk of people wanting manual 901 batteries, and while it is pretty cool having one I prefer the autos. At any rate, it's pretty simple to make one yourself if you want.

The USB passthru is extremely simple to make, and there are plenty of good FAQ about them here on the boards if you want to make one - no point in me reinventing the wheel other than saying it's not a bad idea to include a resistor inside it to lower the voltage (or toss in a diode to drop it by .5v with no fiddling about with math).

The manual battery is just as simple, and one thing I would recommend is soldering short lengths of stiff wire (like the legs from an LED or diode) onto the wiring to make soldering the fitting for the atomizer easier.

The picture of the micro switch is the kind that I am using, sorry no part numbers - I pulled them out of an old GM radio PCB.

If anyone has questions I will try to answer them for you, but you should have at least some experience with kind of thing before attempting a manual battery. Those things are way too close to you face for a beginner.

Cool...... this seems like a good place for discussion. i have a 901 usb pass that worked ok for about 2 days. First I did not know that a usb pass had a "time out" built in. My pass has the 5 second cut off like the battery. I would have to let off the button after 4 seconds for 1 second to be able to go another 4 seconds and repete. NOW the sucker won't shut down untill the 5 second delay. I gonna take it apart and disconnect what i assume is the same micro chip that's in the battery to try and eliminate the delay. Any suggestions befor i tare into it?
Thanks in advance,.

Love the search button LOL

Well, if you eliminate the PCB inside the passthru and just run the switch you will eliminate the delay. Problem with that is you will send 5V to your atomizer - which will kill it faster, plus you will have no safety features.

If you eliminate the PCB and replace it with resistors you can bring the voltage down, but you will still have no safety circuit in there. Might not be the best idea...

I make all of my passthroughs without PCBs, resistors or LED's. They are straight, manual passthroughs. 5v is a wonderful thing. Adopt good vaping practices at higher voltages and atomizers do quite well.

Yes, Ran the straight 5v. I like the extra voltage. The problem was the tact switch tho. I will need to rob a switch from somthing and fit it in there somehow.
Thanks!

5V is pretty awesome, I'm not saying I never tried it..... I just don't like to recommend anything like that or removing safety features to someone making their first mod - for obvious reasons.

What are your good vaping practices? Even dripping and hauling on the stick in short bursts has led to all my atomizers burning out at 5V. Do you start with new atty's and then condition them from the get go at 5V? Please explain, I am totally willing to go back to it for the vapour production anf flavor if I can stop frying the attys.

Same here Shaik, Im planning to make a passthrough with a resistor or diode.. Not gonna risk burning out the atty... i still gotta check the output of my laptop usb... prolly the standard 5v 500mAh

I can't vape from the USB ports on my laptop unless the AC adaptor is plugged in. Try yours both ways and see what happens.

Shaik : This is to prevent windows from reducing power to the USB port(s) when AC unplugged (to save power).. but it will probably drain the battery faster

right click My Computer > properties > hardware tab > Device manager > Universal Serial Bus controllers > right click{pick USB port; "USB Root Hub" or something similar} > properties > Power Management > uncheck "Allow the computer to turn off this device to save power." > Press OK

There will be many ports, as many as you can see on your computer...

I do this to all my usb ports

Wow....... thanks for the tip, I had no idea. I will give that a try!
