Wick Posted July 27, 2015 Author Report Share Posted July 27, 2015 Hey guys, May have been already asked and stated, but I can not find it so any help or direction would be greatly appreciated! Two questions really: 1) what would be the ideal setup to generate the most accurate discharge profiles? ie. What exact type and size resistor, wattage and ohm rating, best suggested connection of resistor for running the analyzer. 2) is there any running file sharing on battery specific CSV discharge files? Best, Wick Link to comment Share on other sites More sharing options...
John Posted July 27, 2015 Report Share Posted July 27, 2015 We use four 50 watt, 1 ohm power resistors in parallel for a total output resistance of .25.I don't know of any for #2 yet. Link to comment Share on other sites More sharing options...

Vape_Like_A_Boss Posted July 29, 2015 Report Share Posted July 29, 2015 How are you guys connecting the resistors to the board? Can it be done accurately with the resistor bank run through the 510 connection or is it being hooked up instead of a 510 for testing? Link to comment Share on other sites More sharing options...

Was wondering the same myself, or if connecting the array to a "trusted" atomizer directly would suffice in providing accurate results? John, any way you can shoot us a pic of your setup? Are you running the resistors in open air? Attached to a heat sink? Chassis mount (alum case) resistor, film type?? Ya I'm a bit lost here.

John Posted July 29, 2015 Report Share Posted July 29, 2015 Sure, I will throw up a picture of my setup. Mine is overkill, because it will sink 200w continuously, but you will get the idea. For battery analyzer it doesn't matter whether how good your setup is, as long as the connections are reliable and the resistors can take the heat. All it needs is somewhere for the energy to go.

Wick Posted July 29, 2015 Author Report Share Posted July 29, 2015 Thanks John, that's what I thought but wanted to be sure. Wick Link to comment Share on other sites More sharing options...
VapingBad Posted July 29, 2015 Report Share Posted July 29, 2015 So a 50 W air cooled coil would do it? Link to comment Share on other sites More sharing options...

John Posted July 29, 2015 Report Share Posted July 29, 2015 Sure. Make sure it is really big and don't use nickel for this one. You want a constant resistance. Link to comment Share on other sites More sharing options...
VapingBad Posted July 29, 2015 Report Share Posted July 29, 2015 Yep big kanthal suspension spring, I was thinking of twisting some 0.5 mm and having the mod in a stand when I do it. I could even wrap it around some 5 mm Cu tube I have after wrapping that the in PTFE if I had to loose more heat. Link to comment Share on other sites More sharing options...
scoopy Posted July 29, 2015 Report Share Posted July 29, 2015 John could I fasten 4 1 ohm coils in the posts of an atty at 50 watts to run the test?Or would making a 1 ohm coil at 50 watts be the way? Link to comment Share on other sites More sharing options...
John Posted July 29, 2015 Report Share Posted July 29, 2015 4 one ohm coils would work quite well. This is my battery analyzer test setup. It is somewhat... larger... than strictly speaking necessary (it will handle 200 watts continually) and it is permanently soldered to a test board (but I have thousands of those) Link to comment Share on other sites More sharing options...
Wick Posted July 29, 2015 Author Report Share Posted July 29, 2015 That's a great rig John!! That I'm sure can eat up that heat!! Thanks for the pic!! Link to comment Share on other sites More sharing options...
awsum140 Posted October 1, 2015 Report Share Posted October 1, 2015 John, I assume, and we all know what that can do, that you used 12 gauge wire for interconnections of the resistors and to the atomizer terminals. Link to comment Share on other sites More sharing options...

I am going to build a unitwith two 50w resisters. Actually these https://www.amazon.com/gp/product/B0087ZCYTK/ref=ya_st_dp_summary I am assuming that I'll be good to run the test at 50w without any issues. Am I assuming correctly?

AMDtrucking Posted January 7, 2016 Report Share Posted January 7, 2016 What is the recommended resistance of the resistor?I made a rig from 100W 0.5?, but I'm not sure it is the right one.It's getting pretty hot (175°F +) and I had to add an extension, to move it away from my mod.
