New Batteries

[Brian Liberatore]

Ok folks. Need some help here. I am looking at higher wattage/low resistance builds. What 18650 batteries are best for the 20A+ continuous draw builds. My Imren Gold just ain’t cutting it.

120-180w .18 coils
Regulated mod
Dual battery.

Thanks in advance.

I personally like the Sony VTCs. I believe all the iterations have the amp draw for that. I'm sure more qualified people will pipe up in a bit. A good place to get them I have found is RTD vapor.

Highest amperage 18650 I know of are the Samsung 20S @ 30A. For high amp draw people often use the VTC5A which is 25A with slightly more mah.

Yep. VTC5a's are 25 amps and will do the wattage you want with somewhere around 2600 mah. Best battery brands are LG, Sony, Samsung, though I think there is a newer kid on the block - Murata? Most other companies including Imren use the lesser batteries from the first brands I listed, wrap them with their own label and put unrealistic ratings on them.

On a regulated device, the maximum current is only important when the battery(s) start to reach their cut off voltage. Less voltage = more current to reach your prescribed wattage

To determine the correct battery with a regulated mod, take your wattage, divide by the amount of cells – this will equal Watts Per Battery (Wbatt)

Take Wbatt, divide by your cut off voltage and then divide by the efficiency of the device. If you do not know the efficiency a good figure is 90%. This will equal your Amps Per Battery (Abatt)

So…if using a dual cell device at 180 watts, and the cut off is 3.2 volts and assuming 90% efficiency the equation will be…

Wbatt = 180/2 = 90
Abatt = 90/3.2/0.9 = 31 amps per battery.

The highest rated 18650 cell I am aware of is the 30 amp Samsung 20S. At 180 watts you are not leaving much headroom for variances such as a lower cut off or less efficient device. 170 watts or below you should be fine with the Samsung 20S

Imren batteries are re-wraps; don't waste your money. Are You Using a Rewrap (Rebranded or Aftermarket) Battery?

Imren Gold 15A 3000mAh 18650...accurately rated but useless “max” rating

Imren Gold 20A 3000mAh 18650...almost accurately rated but useless “max” rating

Imren Gold 30A 3000mAh 18650 Bench Test Results...a ridiculously overrated battery​

Try to stick with authentic Lg, Samsung, or Sony (Murata) battery brands.

-If you use a good quality 15 amp CDR battery like the Samsung 30Q or Sony VTC6, then you are good up to 45 watts per battery; 90 watts using two; 135 watts for three batteries.​

-If you use a good quality 20 amp CDR battery like the LG HG2 or Samsung 25R then you are good for 60 watts per battery. If using a 2-battery regulated mod, you're good for 120 watts as you have two batteries. If you are using a 3-battery mod, you're good for 180.

-If you use a single 25 amp CDR battery like the Sony VTC5A, then you are good for 75 watts per battery, 150 watts for two batteries, and 225 watts with three.

-If you use a single 30 amp CDR battery like the LG HB6 you are good up to 90 watts; with a pair of 30 amp CDR batteries you could safely do 180 watts.​
