26650 mech mod help!

[Nastybladegamez]

Hi all. I'm hoping someone can help me out in regards to safe ranges for my batteries. I have an orange mnke IMR26650 that says MH46698 and I have a green 26650 efest 4200mah 3.7v 20a/50a.

My friend sold me all this stuff and said I shouldn't build any coils that read lower than .10

I wanted to find a forum and ask if this was true. I built a dual parallel 5 wrap with 24g kanthal, and my ohm tester says 0.10

At one point it said 0.09 but I tested it again later and it came out at 0.10 again. Ohm reader is brand new and working properly.

Hopefully someone out there uses these batteries and can give me some advice on ohm safe range. Thanks in advanced to all who ready or reply!

What you were told and what you are doing is not advisable. There is a lot of risk building to such a low resistance. Also, we do not know what physical condition the batteries are in and how much use and abuse they have been through.

Coil wrapping | Steam Engine | free vaping calculators use this site to test your ohms and amps you would be pushing out on each build. also the coil part is very handy aswell. But I would do some research and become knowledgeable with batteries in general. IMO once you go below .2 builds things can get a little sticky if you dont know about battery saftey.

Those are both 20A batteries. The lowest "safe" build with no safety margin whatsoever is 0.21ohm.

What atty are you building for and what gauge wire?

As has been said already both those batteries have a maximum continuous amp rating of 20A. Here's a Ohm's law calculator that you can use to figure this stuff out with. Enter a 'Resistance' of 0.21 ohms and a battery 'Voltage' of 4.2V (the voltage of that battery fresh off the charger) and hit enter. 'Current' will then show 20 amps. Lower the resistance and the battery current (amp) draw will go up further.

The problem with this scenario is that your ohms reader has a tolerance so when it reads 0.21 ohms it could be off a bit, say between 0.16-0.27 ohms. At 0.16 ohms you'll be drawing 26.25 amps on a 20 amp battery. Because of that, using 20A batteries I try to stay above around 0.27 ohms. You can buy 30A batteries like Sony VTC3 and VTC4 that are rated 30A to go lower in resistance if you want to.

If you run a 20A battery at more than 20A, it will heat up in use. Get it too hot and it will vent and that can be painful. 0.10 ohms will draw 42 amps, which is way over the safe limit of these batteries.

Please listen to the experienced forum goers above. It's funny because I have both of those batts for my 26650 mods. The MNKE is a 20A continuous so you should not be running a .1 build on it, no matter how quick Your pulses are. The risk is not worth it. Really, unless you are a super experienced Vaper with some high dollar ohm meter and a suitable Mod/battery combo, you probably shouldn't be using a coil built to .1. It may work for a bit but man you don't want to see a 26650 vent anywhere near you, and that's where this seems to be heading. Also, I wouldn't trust that efest. Mine also says 4200 mah but I can tell you, vaping side by side with the MNKE, it is not 4200 mah. And a lot of research has told me that efest lies about their batt performance #s/ratings.
I love parallel builds.i build my rdas between .3 - .5 ohm. I also like to rebuild my kanger subtank factory OCCs with parallel coils, after I drill out the juice holes to 3mm. An amazing vape IMO!
What are your coil IDs? What type of wire?
You've def come to the right place for answers though everyone here wants you to be a happy Vaper, spewing clouds or chasing flavors. safely.

be nice to your batteries.... .3 should be a good resistance. Pushing lower than .2 is asking for an early death of the battery, .1 is asking for trouble.....
just because a car can do more than 120mph doesnt make it safe to do it.... using ohms lower than the battey can handle is like driving on the hiway at 60 mph ... in first gear... the motor will go poof.

Funny you should mention that. I know what the inaccuracy of my el-cheapo atomizer ohm reader is (because I was able to test it against a calibrated low-range ohm meter) and I still don't really trust it below 0.20 - 0.3 ohms.
