Is this battery safe for sub ohms?

[subvapor]

Hello everyone i just recently got a rda running a dual coil build at 0.8 ohm on my ipv mini 2 70w my battery is efest imr 18650 3.7v li-mn high drain rechargeable battery 35a 2500mah its the purple one im still learning ohms law and my math shows its safe vaping at full 70w at 7.5v but just learning still so i want some opinions on that plus i want to try lower ohms and wondering what the lowest i should build at would be or any batterys you all would recommend or mods for round $100 dollar's that hold more batterys then one

The ipv mini that you are using is a regulated mod, it will let you know when the ohms are too low for it to fire normally by saying "Low Resistance". If you were to use an unregulated mod the battery shown in that picture would be safe down to roughly a 0.11 ohm build. If you are ever unsure visit ohmslawcalculator.com and input the voltage (that battery is 3.7) and the resistance (ohms) then press calculate. The main thing that you'll want to look at is the amps, if it is drawing more than 35A it will be unsafe with that battery.

Thanks for the info i built a 1.1 ohm coil and vaping that for now just to play it safe and still getting clouds

At what wattage is the key. It's a regulated mod - resistance is futile. (Or at least not part of the equation other than will the chip fire it and how much wattage it will allow you to set) The draw on the battery is governed by the chip based on wattage setting, the voltage available from the battery and the limits of the chip. If you run your mod at 70W all the time you are pushing the limits of the battery as the available voltage drops. Figuring 95% efficiency for the chip you begin to exceed 20A at 70W when the battery reaches 3.6V. For 60W or less the 20A battery is no problem. There are no 35A 2500 mAh batteries, all the 2500 mAh and higher batteries on the market today are no more than 20A continuous. The IPV Mini 2 70W has an input current limit of 30A (Go to the APV preset menu and select the IPV Mini 2 http://www.steam-engine.org/modrange.asp .
If you want to run 70W regularly then you'd be better off with a 2100 mAh 30A battery. Either a VTC4 or there are a couple of Efest that test well. http://liionwholesale.com/blogs/rev...2100mah-38a-vs-efest-2100mah-30a-test-results.
