That makes 2 of us. Unfortunately, that doesn't answer any of my questions [/QUOTE] yes that will work! i used 4 high power 1ohm resistors in a velocity, it will take anything between 1/2 an hour to an hour. just make sure you don't leave it unattended when you do it, those wires will get hot and thats a fire risk

well accurate for my device, I had the same issue where i was getting weak battery at about 20% at 14.43, and at 11.09 when it hits 0% i can get 4 or 5 vapes out of it before i get the weak battery , so it works for me. the mod I have just made has a 2200mah turnigy nanotech A-spec in it and that should read 24.42 if it was 2200 mah but the battery analyser came out to 23.62, so 0.8 lower or 3.3%(I can live with that) . but it had only had a couple of charge cycles so i will give it another run through in a week to see if it has changed. the vt 200 worked out at 23% lower, ..... i am not so sure that is acceptable this works out to a 1000mah battery

My first attempt at a mod! I have had three temp control mods, Evic vt ( kept jumping out of tc mode) Ipv4s good on titanium with 100 joules but 50 joules on nickel not enough) And finally cigar vt200. I was so impressed with the chip, but dissapointed with the battery life (about 8 hours) So I thought I would make one that I can use all day without running out of charge, and also one that can take a lot of abuse, (I am a builder, so it needs to be able to withstand some rough treatment and a fair share of knocks!) Battery analyser has returned 23.79 compared to 24.42 it should be for a 2200 mah battery so quite happy with that. At the end of my work day I still have 45% battery life and with some quite heavy vaping in the evening normally ends up with about 20% Not the prettiest, smallest or lightest .................. But nor am I

Hi, I have done the full test on my h cigar vt200 The reading came out at 11.09 The battery meter is spot on now. Search my posts Here you will find my battery CSv. It is a text file but if you save it as a CSv file it will work

Hi, just made my first ever mod! I have just ran the case analyzer and the results are a lot different to the standard set. The question is, Should I be worried? Case cooling time constant 337.93s Case heating constant. 316.03 Case USB charge temp rise. 7.95 F 18.59 F/A Thanks in advance

is your cut off set to 3.11v?[/QUOTE] Nope cut off is set to 3.09

The L means low carbon

not so sure the battery capacity is all they claim! I ran the battery analyser on a vt 200 and the result was 11.09Wh when i was running the battery at 14.43 i was getting "weak battery " at 20% now at 11.09 with the same coil and setup it vapes all the way down to 0% battery and then 4-5 puffs after that it displays weak battery. so not too happy it only has 11.09 Wh but i do now have an accurate battery meter! if you want to try my battery csv from the analyser it is below:- i changed it to a .txt file to upload but if you change it to or save it as a .csv it will work hcigar_vt200battery.txt

thanks for the reply, after reading more on steam engines TCR calculatorit states "SensitivityUnder "Sensitivity", you'll se a number like for instance 81 %. This means that in the temperature range typical to vaping, the resistance change will be 81 % of that of the resistance change would have been for a pure Ni200 coil. (A Ni200 coil will always score 100%.) A higher number means that your temperature control will be more accurate. It is theoretically possible to score higher than 100 %, but first you'll have to find a coil material with a higher TCR than Ni200. How low you can go while maintaining reasonably accurate temperature control, depends on your 510 connection, your atomizer, your building skills, and more." and as sensitivity= temp control accuracy here are the figures for different coil materials:- kanthal A1 0% Kanthal D 1% nichrom N60 9% SS316L 17% SS317L 20% titanium 1 59% NI200 100%

Dry Burn experiment Ok a controlled experiment all settings as follows power setting 100 watts preheat power 200 watts preheat punch 5 preheat time limit 1s puff for 10 second (auto through device monitor) test at 350, 400 450 degrees farenheit all test done on velocity rda with muji cotton coil 1: ni200 0.4mm 8 spaced wraps 3mm diameter 0.91 ohms stable on escribe i wont put pics up for this one !!! graph eratic as expected, but there was no charring or colouring at alll until i took it up to 500 (just a slight colour to the cotton)550 (light brown charring)and 600 degrees, dark brown charring) Coil 2:- titanium .4mm 8 spaced wraps 3mm diameter 0.452 ohms stable on escribe Well that surprised me! almost identical results to the NI200 no colour change at 350,400 450, very very slight colour at 500, light brown at 550 anddarker at 600, but not as dark as the ni200 at 600. now for the 317L... Coil 2:- 317L 0.45mm 8 spaced wraps 3mm diameter 0.529 ohms stable on escribe 350 degrees very light brown similar colour to the NI200 and TI at 500 degrees, 400 light brown again, similar colour to the ti and NI at 150 degrees higher, 450 burnt through the cotton, 600 ignited instantly so there you have it... it seems that SS is getting about 150 degrees hotter than NI200 or Ti throughout the range, so either the csv file is wrong or the csv file is wrong, ..... i cannot think of a second reason! but it fits with my experience with all three wires, i like NI and TI at 420-480 degrees and 317L at 300-340.. I hope this has helps. and i agree we need more disussion on SS I am sure someone could ccome up with a revised resistivity csv for stainless

quote "mknight 8 hours ago Could it be that you need to use tcr for 316l? I noticed most ss out there is 316 or 316l. Getting killer performance with dual coil, 24g at 0.2 ohm. Setting tcr to 0.001" 317 and 316 should perform pretty much the same as each other, 317 is just a bit more corrosion resistant than 316 (which should mean safer possibly) I have downloaded the 317l csv from steam engine which should match the difference in resistivity between 316 and 317 The 'L' just means there is less carbon in the alloy which just means they are more resistant to intergranular corosion when used for welding......I trust we are not vaping at those temperatures!! for anyone thats interested here is the difference in resistivity:-

Hi, just wanted to share some screens from device monitor, and wonder if anyone can tell me what is going on here. with NI200 the selected temperature is hit and it remains there nice and steady, with titanium it gets to the temp and then fluctuates a little with 317L Stainless it gets to the temp then fluctuates quite wildly Now the vape on all three is very good so i have no complaints, in fact i prefer the taste of the SS out of all three, and it is a dream to work with. I am presuming the difference in the charts is because the temp coeficient chart gradients are a lot shallower on the SS therefore the resistance difference between two temperatures is a lot smaller than ni200 or titanium, which would also explain the slight variation on the TI coils. am i correct in thinking this ? Thanks in advance
