How low can this go??

[CraxyBoxMaker]

I got a imr efest 26650 4200 mah battery at 20a/50a how low of a resistance can i go??

.21 for the 20 amp.
If you want to trust pulse .08

With that being said you will have zero safety margin if shit goes south.

^^ This.

http://www.ohmslawcalculator.com/ohms_law_calculator.php. On a mech, a fully charged battery puts out 4.2V. With that, you can figure out the resistance for your amp limits. With regulated, you can just adjust watts instead of volts.

Just a up date its not south yet .03 18g coils duel lol

it's your face and hands yo.
If you wanna flirt with Darwin and his award that is your call.

Well it is a new year and there will be another Darwin award recipient lol.

0.03 is asking for trouble, hope to hear you post a month later with no issues and all of your fingers.

Its a 50 pulse amp from what i have read but my c4 sonys have lasted for a year on there limit and its not like im firing it at 10sec triggers

 

[BigNasty]

They maybe listed as a 50amp pulse but you are forgetting the battery sag and voltage drop in the mod itself.
below .1 land you are in realm of dead short. .03 is no breathing room if you nuke an insulator.

If you've been vaping at 0.03 for a year (reading that right?) without any nuclear meltdowns, the Darwin award may belong to someone else

Just not worth the chance Murphy's law visits to me though.

 

[CraxyBoxMaker]

No on sony im only going like .2 or so

 

[fq06]

Got it, that's a sane build.

"but my c4 sonys have lasted for a year"
Some battery manufacturer should name their next release C4 lol

On a side note, there is no industry standard on discharge ratings. Been around lithium chemistry battery's for over a decade racing rc cars and there are a lot of bullshit number out there. Like 100c 6500 mah 2s packs, they can not deliver 650 amps. 12g wire would be melting and shit would be going sideways real fast but they put it on their packs anyway.

 

[CraxyBoxMaker]

I do agree

 

[CraxyBoxMaker]

Sony has a c4 lol

 

[fq06]

Now I need a new battery lol

You should always operate with a 0.2 ohm safety buffer. Especially if you're unfamiliar with Ohm's Law, and on an internet forum asking what your battery can handle.

"Hai guiz! This awesum dood at the vape shop with a big scar down the side of his face said these batts r the bom-diggity! He runs a 0.0001 ohm twisted, bent, hammered DNA helix build he calls the FUBAR coil. I saw it on YouToobz! Is it safe?"
