HELP! Resistance and battery

[Daniel85]

Hi everyone,

I am new to vaping and I started doing my own rba single coil for my TFV4. Currently I am using a D2 mod.

My question is:

1) TFV4 states 0.85ohm - what if my coil resistance is more than 1ohm or 2ohm. How will it affect

2) what if my coil resistance is less that 0.5ohm?

I heard that if the resistance is higher, the batter will drain out slower.
Is there any other effect on my battery?

Bump.

if you set the Watts to be the same on either coil, then no, the battery will not last longer.... kinda like running your car in first gear at 3000 rpm or 4th gear at 3000 rpm... your speed increases but the gas usage remains the same.

Hi Bunny, thanks for replying...........meaning if

1) my coil is more than 0.85 ohm....say 2ohm......the battery will drain like mad assuming i am vaping at 20 watt..........because of the amount of heat it need to generate

2) if my coil is 0.8ohm or 0.7ohm......i get vape faster........but because of the energy use.........it still dry out my battery fast........

I heard of cases where the tank exploded...was like the scenario the tank can only take 0.85 ohm and I am burning it at 0.4ohm which heats up the tank faster than it cool...and........it explode

What about battery explosion

thanks tommy for bumping my threat to get me understand from the pros here

If the mod is working correctly, it should protect you from blowing up your battery. Tanks don't explode. When you build your coil, test it with an ohm reader before you put it on the mod. That's your first chance to avoid a problem. When you hit the button on your mod, it does some math and figures out how many volts it needs to use to get the watts you set at the resistance you build. You can run a .2 ohm build at 80W and a 1.6 ohm build at 20W and it will use the same voltage to fire it. The resistance is what determines how fast your batteries drain. Resistance does just what it says. It "resists" the flow of electricity. Higher resistance will slow down the flow, making your batteries last longer, but there are still more variables to factor in. The gauge of your wire plays into it too. 1 ohm with 28G wire takes very little energy to heat up. 1 ohm with 22 gauge wire takes a LOT of energy to heat because it is a LOT more metal.

Thanks Hans, currently I am out of budget to get a ohm reader....... I am looking at the coil master 512 as it gives the convenience and has a firing mech also....mean while I guess I just use my mod as a gauge...

I just rebuild my coil for my single RBA TFV4........reading at 0.92 ohm on average....what does it mean when the website says only 0.85 ohm for TFV4 single coil? That is one thing I am curious about....

How will that affect me? if they say 1.1ohm - 1.8ohm (75 - 100watt)....means if my coil is reading between the stated ohm, it can be used from 75 - 100watt is that it?
