My first mod 5.26 Volt

I ordered a DID rebuildable Atomizer and it came in this metal case, so I ordered a 4 AA battery case from ebay for $1, lol and a button, 510 adapter drilled a two holes solider the wires up, then I tested it with a mulitmeter and it was showing 5.26 volts. the batteries used are 1.2 volt ni-mh AA 3000mAh rechargeable, I Have a bout 50 of this I bought on ebay, for the kids toys and remotes So then I tested it and wow it works perfect with the DID Atomizer, very smooth and lots of vapor.
It probably cost around $5 in parts to build.

Hey canukvapes

Nice mod!! Just my kind of thing being cheap. Welcome to the club!!! Nice that you are using gear that you have on hand with the batteries. 5.6v is out of my comfort range, but if its good for you what the fark!! It just goes to prove that when Armageddon hits, we will be good to carry on when PV's are not available!! Very nice!! I have been eying those boxes but never got hold;d of one.

 

Hi Robray I only paid Like $8.97 for the DID rebuildable Atomizer with the box and shipping was only $5.33 for the Atomizer and also a lava tube
DID REPAIRABLE GENESIS STYLE ATOMIZER
I also think its cool that we can build things like this at home

Not a big fan of rebuildables at the moment. Have a few but they are just on standby for when the proverbial hits the fan. I am basically to lazy. I can get my jollies with off the shelf Vivi Novas etc.

 

ya rebuildables are good but some are crap like this cobra one i purchased the wick hole is too close to the metal cap, so basically it destroyed 4 manual batteries I had, luckily they were cheap batteries I bought on gumtree, 9 batteries for like $30. But the DID rebuildable Atomizer from the link above I never had a issue with.

what resistance you running on hte did?

 

Not sure my multimeter doesn't give a proper result, it jumps everywhere, volts works fine, but ohms its just keeps showing random number, never any constants, I'll order a new one on ebay in about 5 mins, lol but I wrapped it 5 times and its 28 .comge wire.
Jeff

 

should still be fairly low. no troubles running that much volts through it? i always get a bit paranoid cranking up volts on a low ohm coil.

 

no there wasn't any trouble, but the batteries are dead, So I recharging them and going to see how long it last, I should probably add a regulator on it.
Jeff

 

very cool. great stuff!

 

I wonder what voltage you are getting under load. Its going to pretty much determined by the battery quality, 4.4V I imagine if they are reasonable batts.

5 wraps of 28 is going to be sub 2Ω, so punching out 10W or so at a guess.

 

5 wraps of 28G Kanthal on my AGA-T, which has a 3mm Dia. wick, gives me a 1.1ohm coil so the coil on that CHiD (it's not a real DiD if you got it from that place, it's a Chinese DiD clone or CHid) will be around the same if the wick hole is 3mm Dia. If the wick hole is smaller then it will be even lower ohms.

 

Ive got one of those boxes if u wnt it robray. Just pm me your address n ill send it off for you today
Cheers

Nice job on the modding, terrible job on your FB page, Jeff.

What was it about my post that you didn't like & felt compelled to delete?
Was it the facts that you couldn't refute or was it the link to AVF, intended to help newbies find their way here to get better information than your false accusations & incorrect opinions?
If your FB page is there to help newbies as it claims, then I don't see why you would remove a link to AVF, where they will be able to get better help.
So I can only assume it's be.comse you don't like anyone posting the truth & showing you to be telling porkies & making false claims about Chinese ejuice manufacture.

Sure you had a bad experience with some Chinese juice but there are some that have had bad experiences with juice from other countries including USA, claiming that & I quote, "Chinese Vendors are known to add some terrible toxins." Is nothing short of scaremongering bullshit.
Not only are you representing yourself on that FB page but you are also representing & misrepresenting canadans in general, due to the page's Name "canuk Vapes", what you are doing is irresponsible & casting a slur over the canuk vaping community.

 

I calculate closer to 20W than 10W. Using Noe's measurement of 1.1ohms and Stoney's insight to 4.4v under load, that would 17.6W. Mighty hot methinks.

Your FB is still libellous.

This is 4x NiMH cells linked in series, are they safe to run at these loads?
Using your calculation of 17.6W, I get 4A @ 4.4V. Given that the nominal voltage of a NiMH cell is 1.2V, I think that means each cell in the series is pumping out 1.1v @ 4A, so possibly exceeding the safe operating limits?

 

my estimation of 4.4v is just off the cuff, but takes into account contact resistances, assuming the terminals in the batt box are ok, wire losses and switch losses. i imagine the cells are putting out a little over 1.1v but probably losing 0.2 to 0.5v through everything else. I doubt they would manage 1.2v under load. cheap cells could well drop to under 1v in reality.
AA nimh are not particularly dangerous, more likely the switch, wires or contacts will fail first, long before the case melts.
not likely to explode, a fire is a possibility, usually one of the cells simply dies first and acts as a big fuse.


its very unlikely its going to manage 17W imo. if the atty is that low then losses elsewhere or simply internal cell resistance will keep it down to a lower current.

5.26v is the no load voltage, thats why I was interested in seeing a loaded voltage.

 

5.26v means each cell is adding 1.315V but that would be when fully charged or near to fully charged, under no load. So if the voltage is going to drop significantly then the amps would be trying to take up the slack to match the ohms on the coil & supply the needed watts, at least that is how I understand it.

So maybe there is a 5A draw on the batts? You aren't going to get a lot of vape time out of the mod & it is going to generate a lot of heat.
Here is a graph, of a good quality, high capacity, AA NiMH cell's discharge rates, the cells Jeff is using state they are 3000mah but I highly doubt they are anywhere near 3000mah or the quality of the batt in this graph:

The 5.26v is when I connect the multimeter to 510 threaded adapter and I press the fire button, It vapes really nice but it uses up the batteries in about 75-100 puffs, I might take apart one of blown 510 batteries and adapt the circuit to it, if anything I would like to turn down the amps, really it should last 2-3x longer than most ego style batts, but since it doesn't have any restrictions it doesn't last all that long, but the batteries charge quick around 1.5hrs.
