battery drain and readings

[dezyner]

ok, before I bother those kind folks at ProVape about this issue, want to ask here. Provari 2.5 mini. Love it. Best investment yet in vaping for me. Got the twins and hippo for it also. got some rbas to play with recently. Nice. Here's where my question begins. I've read as much as I could find here and online, but I still have questions. the rbas I'm setting up between 1.5 ohms and 2.2 ohms. nothing below or above those numbers. Noticed my battery life decreasing, or more accurately, the button flashing sooner and decreased battery time. The 1.5ohm coils I run at about 3.5 - 4.0 volts. the 2's, I run 4.v and up. I basically take the ohms resistance, add 2 to it for voltage, and run with it. So far, great vape. But when it comes to the battery life, it's getting to the point that I said uncle, broke down and decided to ask here.

First thing I did was clean the threads and connections real good, make sure it wasn't a connection grounding issue.

Then I multi meter tested the batts, make sure they are charged. Good there.

When I put a battery in the ProV "CB" test mode, I am getting number drops under load. If the battery without a coil reads 4.1, it drops to 4.0 volts with a coil on, regardless of 1.5 or 2.5 ohm coil. with 18650 batt.

but when I do this with an 18350 batt, the drop is much bigger. cb shows 3.7 v, but with atty of 1.5 coil, it drops to 3.4 volts on the "CB" menu.

I am not getting the same usage times I used to get. Basically is it because of Ohms law and the math? Buy more 1860 batteries kinda gig? I can live with that, cause I am not going back to clearos after this. Is it possible the connection with the hippo is adding to this?

Is it just the slack I am seeing, or does my board have issues?

As always, thanks guys and gals.

Rest assured, the problem isn't with your Provari or your batteries. I've noted the same thing with my AGA T2's on a Mini and regular Provari. Doesn't matter if I'm using a 18350, 18490, or 18650 AW imr. I'm getting less battery usage with the RBA's.

I don't know enough about amp draw, resistance, and voltage to be able to understand let alone explain why this is so.

cool, at least the info is. didn't want to worry, or ask provape if it was a non issue. only happened when I introduced the rbas into the mix, so I had hoped it was just the math and physics of it, and I aint into a crash course of learning the math right now either. although it is worth mentioning, it seems to affect the 18650 a little less in my case. dunno why either. more aw batteries it is. lol. i'm not going backwards, would rather fork over the money for more batts any day. at least i was able to kick my nicotine down, so even trade off. thanks. appreciate it.

RBAs just crush your battery life, especially running lo-res. generally, you end up running them at higher wattage and drawing more amps.

Not a problem with your ProVari. Just a reality of running RBAs.

Part of it as well might be how long your draw is. My average draw time on something like a RDA with silica is about 5 seconds. Counting the time it takes the coils to heat up I'd say my average draw time on a genesis is closer to 10-13 seconds. It could be that you're taking longer draws on your genesis and not really noticing. Even if its only another 3 seconds per draw that adds up to a lot of time with that button held down.

1 genny, 2 silica rbas, and yeah, my draw time is a little long, but basically, I use the same ohm to voltage spread to all my stuff. i take the ohms, and add 2, that's the voltage usually. i know it's a BS system arbitrarily I think, read it somewhere, got tired of looking at the "safe" zone charts. so I was always working on the assumption that 2 ohms at 4 volts was about the same strain as 1.5 ohms at 3.5 volts. I'm lazy, never crunched the numbers or learned the equations, never seemed to drag down my spinners or twists with those ratios, or even the ProV before. throw the rbas on there, and it seemed considerably shorter. And also, weird thing for me was the battery check function on the ProV says 3.9 without the rba on, and 3.6-3.7 with the rba on there when I check the battery, and the led flashed at higher numbers than I remembered before, one time at 3.7, which I thought was pretty high for the chrage alarm to flash. that's actually more concern than shorter batt charges, I can buy more batteries, and don't even mind, getting better vapes. But I was concerned that the readings were way different with the rba than without. I had never really bothered to check or even noticed before. Just wanted to make sure with you guys that it wasn't in fact, me trashing the batts or the ProV itself. I get it I think, lots of variables have changed. cool. thanks a bunch guys, appreciate the info, always. cheers and thanks again.

This actually didn't occur to me till you mentioned it, but I think you're 100% dead on. Draw time can be super long, especially because of how long it takes the coil to warm up on something like a genny. I also find the battery reading issue interesting and would like to find out the reason behind that.
