Battery Chart

[Brandon Rauls]

According to this battery chart

Typically any battery higher than 2250 mAh can't do sub ohm vaping safely.

I bought these batteries below for my IPV3 Box mod

Can I safely run those batteries at .3 Ohms?

That chart is missing some batteries. The VTC5 is 2600mAh at 30A, Samsung have a few different batteries at around 2500mAh that will do sub-ohm and LG HE2 is 2500mAh at 20A.

I have not seen a review of the MXJO 18650 that I trust that says it is not really a 20A battery and I believe the MXJO website says 35A is a pulse rating which also means they are really 20A.

In your IPV3 the resistance does not matter. You set watts and the mod puts out those watts no matter the resistance. If I were going to run at 150 watts with two 18650 batteries I would get 30A batts.

Well the .3 Ohm build I'm doing according to Steam Engines Ohms law can do .3 Ohms at 5.5v at 18.33A, those batteries being 20A, .3 Ohms at 5.5v at 18.33A would give me some leg room on the amperage to be a bit more safe.

You're using the Ohm's law calculator, which is good for a mech mod, but not regulated mods like the IPV3 with which you set the watts. Go to the Steam Engine battery drain calculator and set it up for regulated, VW, 150 watts and battey volts of 6 (two batts at minimal voltage) and you get 27.78 amps. Then play around with it. Change the ohms, the watts and the battery volts and see what happens to battery drain.

You are setting watts, not volts. Battery drain has nothing to do with ohms in this case. Ohms matter in a mech mod, or if you set the volts in a regulated mod.

I'm not worried about battery drain atm, I mainly just want to know if I can run those MXJO batteries safely at a .3 Ohm build as they are 20A Contin.
Anything under .3 Ohms would take a 30A batt. I believe.

You're not getting this Brandon. Battery drain is the amp discharge, or draw, from the battery. So, if the battery drain at 150 watts with two batts is 27.78 amps each, you need 30a batteries.

 

[Brandon Rauls]

No I know that much, but I'm not looking to run at anything above 100w until I get 30A batteries, I'm probably gonna be sticking to around 80-100 watts until I can afford 30A batteries (Just dumped 500$ on tools to start building, IPV3 Box, and the RDA all together) so 30A batteries will be a couple months away.

 

[ImThatGuy]

100 watts at 0.3ohms = 30a.
80 watts at 0.3ohms = 24a.

Alright, wellp... effit..
Just bought 8 VTC4's from Sony VTC4 >< So now I've got 4 MXJO batteries, and 4 eFest batteries that are a waste.

 

[HecticEnergy]

Word to the wise, always buy batteries from a reputable source. I know these come highly rated:
RTD Vapes
Illumination Supply
Sun Vapers

Amazon and Ebay aren't really a good source as there are A LOT of knockoffs out there. Dunno about sweet vapes. Sorry I posted this after you ordered

How many people across all your threads were telling you 30amp batteries? You were dead set on 0.2 and 0.3ohm builds and using a scheme designed for mech mods not variable wattage devices.

 

[KGB7]

With variable wattage mod like IPV3 its doesnt matter if the battery is 20A or 30A, the on-board chip does all the work for you. So you are fine with 20A batteries under 100watts.

One more time, you not using a Mech Mod. This is where you confusing your self.


I honestly think you shouldn't be building your own coils or using anything above 20watts till you learn everything about VW mod and Mech mod, as well as Ohm laws.

Could you list some sources on this?
To my understanding, you still need high amp batteries as the regulated mods up the amperage in order to up the wattage. Obviously it depends on your build and what you are wattage you are pulling to say what amperage of batteries you are required to use, but to get the full range of wattage out of the mod you are required to use higher amperage batteries, no? I'm no expert, this is just my understanding from what I've read over the last year. As I recall Evolvs DNA 30 would check your battery and if the amperage of the battery wasn't high enough it would limit you to a like 20w for a given build. I'll try to find the article on this later for reference.

 

[KGB7]

DNA30 thats 30 watts. With 1ohm build at 30 watts, you pulling 8amp from the battery.

I looked and couldn't find the link so I'm probably mistaken, I recall reading/seeing on youtube that it wouldn't fire when attempting to pull over 10amps if you put a 10amp battery in there...
sorry for my mis-recollection

You mean 5.48 amps, right?

ummm..... that works as well...lol

thx
