bingbling Posted September 30, 2015 Author Report Share Posted September 30, 2015 Hi, what would be the proper use of battery analyzer? Can I attach just any RDA with a coil and run it or should I have some specific setup? I am a bit hesitant running it because I have heard some people having problems with heat and/or fried boards due to heat etc.Also does it have a great effect on battery life/meter completing the analysis compared to just entering the numbers into the calc? I'm having some difficulties matching my HCigar VT200 battery specifications with real life figures. Entering specified 1300mAh into the calc (14.43) is way off for me, I am getting weak battery at ~25% battery left. So I am down to setting 1100mAh, which so far gives a more accurate battery meter.Any advice please? Link to comment Share on other sites More sharing options...
VapingBad Posted September 30, 2015 Report Share Posted September 30, 2015 No not just an atty, see this threadhttps://forum.evolvapor.com/topic/67481-topic/ Link to comment Share on other sites More sharing options...
bingbling Posted September 30, 2015 Author Report Share Posted September 30, 2015 Right, so I don't have access to those kinda testbeds john is talking about. The thread you linked suggests air cooled coils, so quad coils with 24gauge should be able to handle the heat from 50watts.Something like this? They should barely get warm, if at all. What do you think about that? Link to comment Share on other sites More sharing options...

What do you think about that?If you just use a big circular loop of thick wire in free air, it doesn't get that hot. Making a coil reduces cooling efficiency and allows heat transfer from loop to loop. If you have 24, try twisting 3 or 4 strands (what will fit in your atty) into one large circular loop.

lewisss Posted October 1, 2015 Report Share Posted October 1, 2015 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 Link to comment Share on other sites More sharing options...

There's a discussion going on e-cigaretteforum about this. Some people claim they ran the battery analyzer and have a setting of 14.43 (1300mAh), and their battery meter is 100% accurate according to them.About using your CSV, would that really be totally accurate?

FiB3R Posted October 1, 2015 Report Share Posted October 1, 2015 Is doing it like this ok? 4 x ~13cm 22AWG kanthal = 0.264 OhmsIs it still recommended to use 40W for the test in this case?How long should I expect the test to take? (Vape Cige, VTbox200, claimed 1800mAh)Thanks Link to comment Share on other sites More sharing options...
Popeye Posted October 1, 2015 Report Share Posted October 1, 2015 Id be surprised if you got more than 1200mah tbh Link to comment Share on other sites More sharing options...

FiB3R Posted October 2, 2015 Report Share Posted October 2, 2015 Time to be surprised, Popeye. 14.17 x 1000 / 11.1 = 1276.5765765765771276 mAh, right? Link to comment Share on other sites More sharing options...
FiB3R Posted October 2, 2015 Report Share Posted October 2, 2015 I recorded a couple of log files while doing this.One while it still needed charging first, and was going to take too long at 0.5AAnd a second one where it was almost ready to rock, and just needed a little extra before beginning the test.Anyway, my question is, how do you correctly read the time stamps? It seems messed up to me.http://ge.tt/9QpfT7P2 Link to comment Share on other sites More sharing options...

scoopy Posted October 4, 2015 Report Share Posted October 4, 2015 What is the advantage of running 4 mike? I've been wondering this when I seen John's rig bit he said one 1 ohm power resistor would work fine for the battery analyser. Any feedback would be appreciated because I'm wanting to run the test soon Link to comment Share on other sites More sharing options...
mikepetro Posted October 4, 2015 Report Share Posted October 4, 2015 Four resistors spreads out the heatload. One resistor will get pretty hot unless you use low watts. I used 100w and they got warm but you could still hold them comfortably.4 resistors in parallel is more akin to the attys we run, but I dont know it makes much difference.To me it all about heat dissipation and being able to run the test much faster.

scoopy Posted October 4, 2015 Report Share Posted October 4, 2015 I was told to run it at 40 watts on one 1 ohm resistor Shouldn't that work ok? Link to comment Share on other sites More sharing options...
mikepetro Posted October 4, 2015 Report Share Posted October 4, 2015 I would assume so. I think it will be heavily influence by what that resistor is mounted to. If it it just in open air then it will probably get pretty hot. If it is mounted to some substantial metal then it will be better. Link to comment Share on other sites More sharing options...
scoopy Posted October 4, 2015 Report Share Posted October 4, 2015 What would be good to mount it to So running 4 just let's it stay cooler and do the test faster Link to comment Share on other sites More sharing options...
mikepetro Posted October 4, 2015 Report Share Posted October 4, 2015 Really it all depends on "why" you are running the battery analyzer. If you just want to set your own battery once and forget it then go as cheap as you can. Really, the wH calculator comes pretty damn close for casual use. If you are going to be doing it multiple times then you might want to throw a proper heatsink at it.I mounted mine to a 3lb aluminum heatsink, but then I want to be able to test multiple battery brands without waiting forever..

mikepetro Posted October 4, 2015 Report Share Posted October 4, 2015 From the scrap metal bin at work.Search "surplus heat sink" or similar. You can get one for a few bucks on ebay most likely. Link to comment Share on other sites More sharing options...
