My Sigelei 150 Battery Testing Results (Many Batteries)

[sd3614]

Did some deep testing in my lab (the kitchen snack bar) over the past couple of weeks. What prompted said testing? My new Sig. I discovered it stops well above 0% battery for me and I realize the device performance varies person to person.

Below is the available % of battery the moment it stopped wanting to fire (even for just a second as it may still go a few hit and miss puffs). Real scientific stuff here

TEST ROUND 1 - I'm pretty consistent with a .2 or .3 ohm coil 70-90 watt until done.

EFEST 35A - 33%
VCT4 - 38%
xtar 2100- 41%
*NEW* SUBOHM Brand - 40%
VCT5 - 33%
LG HE4 - 40%
Samsung 25R - 19% >>> Impressive and cheapest battery of the bunch.
*Testing now - LG HE2

I will keep it updated (re-testing the better ones again 1st), but not too many more to test at this time

I was bored and had a pen and a piece a paper so I figured why not.

I run Samsung 18650 25R's in my Sigelei 150W. I have actually been able to make it as low as 10% when using my Haze mini RDA dual coil .3ohm. Once my Sigelei wouldnt fire anymore I got scared, lol! I thought something was wrong. So, I popped on my Arctic and it Vaped like normal with no problems. Reattached RDA and it didn't fire. So I made the assumption that is true. Once my batteries reach a very low power level the mod won't fire the RDA. Makes sense.

Again, this is just when "my" sig 150 experiences those first couple of low batt warnings/not wanting to hit. Surprised and the HE4 vs HE2 comparison. Re-testing Samsungs now and I have each battery marked 1 and 2 so I can rotate. All of these batteries are new, very UN-official but when I think of the cost vs. performance I think it is good info.

I'm not sure I understand what the test are telling you. If your Sig 150 shuts off at the same voltage each time then the percentage-remaining would be the same for each battery, wouldn't it? What are the different percentages telling you? Thanks!

My samsungs give out around 39%...but then again, the two sets I rotate in my sig100w have been in use since November.

Without knowing how many hours, puffs and further exact sciences the data is simply take it for what it is. Perhaps placebo type effects, but when a $15 battery needs changed when it hits 35 or 40% and a $7 dollar "appears to" make it longer on a charge someone who has a Sig may like the info. It makes me think more about which ones I may pop in on the go.

These batteries are not the same, it is not all apples to apples except I ran the same coil and wattage across all the testing. The discharge time from 40% to 20% is not the same length of time as you would get from 100 to 80%.

Like I said I was bored and had a pen.

Thank you, I agree!
And I always enjoy seeing the results of anyone's battery testing.

I only meant to say that I truly and completely don't understand the test results. Not because there are other or allegedly better ways to test, but because I am truly brain-locking here. If you had the time, could you explain what the numbers mean?

If the mod turns off at the same voltage each time (does it?) then a lower percentage number indicates that the cell ran for a longer time before hitting that turnoff voltage?

Thanks!

Theoretically, yes. What the OP is doing is just providing some data from his usage. To further explain what he has done, the Sig shows the percentage of battery life remaining. Depending on what you're asking the mod to do, it might determine the batteries won't provide enough power and this is when you get the "Check Battery" message. All else equal, a battery that stops at 20% has provided more usage than one that stops at 35%.

The OP has adequately described the limitations of the info provided and as he stated, it's not really apples-to-apples yet. Just because the 25Rs run down to 19% doesn't mean they provided more use. It's certainly possible that it takes less use for them to get to 19% than it does the HE4s to get to 40%.

Thanks! Yes, I saw his mention of the limitations and appreciate the time he has taken to do those tests. As I am always interested on anyone's battery testing I wanted to understand what information we could get from his results. Not because I felt that, in any way, his results weren't useful, etc. Only because I was genuinely interested in his results.

I think my biggest problem is that I don't know what the Sig uses to determine remaining battery life, voltage or some other method. That's causing some confusion for me as to what different percentage numbers mean. If one cell stops at 20% and another stops at 40%, and the Sig uses the same voltage to determine the stopping point, I don't know what's going on. Clearly, I need to read up on the Sig!

@sacullen, thank you for your time and explanation! @sd3614, thanks for doing the tests! Looking forward to seeing your updates.

Yep, you got it. I wish these had some type of timer built into them or puff counter like a high end Camera can count pics taken on the CCD.

My Sig 150 was constantly between .2 and .3 ohms for the entire test and wattage was set at mostly 80-90 watts. I can track voltage shown next round, but if I recall it was about 4.4 when it gave the battery low message.

All in all I am not disappointed in anything really, I thought it was cool to just see how each would act.

Yeah, that's the $64,000 question. It's a YiHi board, so the info has to be out there. It's just not easy to find. My guess, and as you suspect as well, is it's related to voltage. Probably uses a formula before/during/after firing to measure how much the batteries are providing. This stuff gets way over my head.

I will say, though, that my 150 drains my batts a lot more than I ever would in a mech, so I rarely let them get down to an indicated 50%. You can count on one hand the number of times I've thrown a battery from a mech on a charger and it's measuring in the 3.6X range. I have a feeling that using it at low wattages my Sig would drain them far past the point at which I'm comfortable.

My new iPV4 took a pair of VTC4s down to 3.0V today. Very dissappointed.

ON a lighter note, this Sig 150 kicks ... ordered a second one..........just in case..................
