Exact batteries for .15 coils? And a second set for higher ohm builds. Please

[vapesmooth123]

I just bought a triple 18650 Wismec Reuleaux DNA200.

I just bought a TFV8 tank that has prebuilt .15 coils that I want to use at full potential. Please link me which batteries I can safely use with .15 or write out the full name of them so I don't get confused with all the choices.

I would also like a recommendation for a second set of batteries that I can get longer life out of but not using such low .15 ohm coils. I don't know exactly how much higher ohms these coils would be since I've never sub ohm vaped but I just bought some RDAs and RTAs and want to do things like dual Clapton builds or stainless steel etc etc. I just know I want dense clouds but with decent battery life for the second set and let me know how low I can build with those batteries.
infinite Thanks.

Sony's have a 30A limit, pretty much the highest on the market with 2600mah capacity. Should be good for what you want to throw at it.
Sony US18650VTC5 2600 mAh
LG's have a higher capacity at 3000mah but a lower amp rating of 20A
LG 18650 HG2 3000 mAh Brown

The evolv DNA 200 chipset has a 23 amp input amp limit.
(from the batteries to the chip)
The sony vtc5 is a 20a CDR cell, not 30a.

Resistance is irrelevant when using a regulated power device.

3000mah cells will give better run time (between recharge cycles)


LG HG2 3000mah 20a cdr
Samsung 30Q 3000mah 20a cdr
AW 3000mah 20a cdr
Sony VTC6 3000mah 20a cdr
Only buy batteries from reputable vendors / dealers to avoid receiving lesser quality, rewrap erroneously labeled or counterfeit cells.

I agree with everything that Topwater Elvis said.


In a regulated mod, the coil isn't connected to the battery. The regulator is. To calculate the current being drawn from each battery when using variable-wattage (VW) mode you need to calculate the maximum wattage each battery supplies.

As an example, the Reuleaux has a maximum wattage rating of 200W. Since it uses three batteries that means each battery supplies 200W / 3 = 67W. For dual parallel or series 150W devices each battery supplies 150W / 2 = 75W. You use this method for series or parallel devices, it doesn't matter.

Once you have the maximum wattage for each battery then you can use the following formula to determine the maximum amount of current that can be drawn from each battery...

Max Amps Per Battery = Max Wattage Per Battery / Minimum Voltage Per Battery

For the Reuleaux the minimum possible cutoff voltage is 9.0V, which is 3.0V per battery (unless you set the cutoff higher). For most other devices the minimum is 3.2V or 3.1V per battery.

Sony's have a 30A limit, pretty much the highest on the market with 2600mah capacity.

The Sony VTC4 2100mah battery is only a 23 amp CDR cell, not 30 amps. Sony VTC4 2000mAh 18650 Retest Results...a great 23A 2100mAh battery

The Sony VTC5 2600mah battery is a 20 amp CDR cell. Sony VTC5 2500mAh 18650 Retest Results...a great 20A 2600mAh battery

You don't need 30 amp batteries for the RX200.

You can get more mah (capacity or run time) with the same 20 amps as the Sony's with the following batteries:

LG INR18650-HG2 20A 3000mAh Bench Retest Results...a great 20A battery!

Samsung 30Q 20A 3000mAh 18650 Bench Retest Results...a great 20A/3000mAh battery!

AW 20A 3000mAh Flat-Top 18650 Bench Test Results...a good high-capacity 20A battery, could be an HG2

I have an RX200 myself, and use the above LG and AW batteries in it.
