Rixter Posted October 27, 2012 Share Posted October 27, 2012 (edited) I get roughly the same 8 watts from my variable voltage device set at 5.3v with a 3.5Ω HR atty as I do with it set at 3.5v with a 1.5Ω LR atty . The difference is that with the first combination, I’m using around 1.5 amps, while the second combination results in 2.3 amps. So my question is: which setup drains a battery faster?

mcquinn Posted October 27, 2012 Share Posted October 27, 2012 (edited) If you are using the same power (watts) then you will be draining the battery at the same rate.When voltage goes up current goes down and vice versa.Voltage is the pressure so more voltage is a greater difference in potential .Current is the amount of flow ,like a bigger hose.

Since my PVs' switches get warm when the current is high, am I correct in assuming that lower current is easier on the switch? Link to comment Share on other sites More sharing options...
mcquinn Posted October 27, 2012 Share Posted October 27, 2012 I would imagine that the switch is seeing the same current flow as it is electronicly switching the device.The voltage reduction circutry will get hot reducing the voltage. Link to comment Share on other sites More sharing options...
Tam Posted October 28, 2012 Share Posted October 28, 2012 So my question is: which setup drains a battery faster? It's the one where I'm chain-vaping... Sorry, no help here. Link to comment Share on other sites More sharing options...
Jeffb Posted October 28, 2012 Share Posted October 28, 2012 I would think the 2.3 amp set up would drain the batt faster Link to comment Share on other sites More sharing options...
mcquinn Posted October 28, 2012 Share Posted October 28, 2012 Correct 2.3 amps is more current flow so it is draing the reserve quicker.The extra current is the heat you are noticing in the area of the regulator. Link to comment Share on other sites More sharing options...
Rixter Posted November 1, 2012 Author Share Posted November 1, 2012 I haven't done a controlled test, but lowering the current does seem to add considerably more vaping time to my eGo-V. I've been using a 3.2Ω Vision V3 at 5.1v (1.6 amps) for a couple of days and I don't have to charge until bed time rather than early evening like I used to. Finally...an all-day 8w+ eGo and no hot switch! Link to comment Share on other sites More sharing options...
mcquinn Posted November 1, 2012 Share Posted November 1, 2012 I really don't think about stuff like that.It is what it is ,I just go with what I like and change batteries whe they go dead.A person could waste a lot of high quality mindless vaping time thinking about physics and such.
