Hello I just bought my first external battery evic vtc dual box mod, and I'm pairing it with my troll rda to get into coil building. Anyways I'm wondering what would be the best battery to get for it, that is capable at running at the 150 watts? It hasn't came in the mail yet but I went ahead and got two sony vtc3 high drain 18650 batteries, but I'm wondering if there is anything out there better for it? or if they will even work?
The vtc3 will work, independent tests rate them at about 28amp CDR. They are low mah so low run time between charges. Suggested batteries to be at that 150watts constantly would be the newer Sony VTC5A (not the standard older VTC5 but the VTC5A) as well as the LG HD2/HD2C and HD4, which are all 25 amp batteries, the VTC5A is 2500mah where the HD series are 2000 to 2100mah. The VTC5A fits the bill the closest, the needed CDR of 25amps for 150 watts, and great mah for run time.
(Watts set/lowest battery charge)/90% chipset efficiency=amps needed
Lowest charge on average per battery is about 3.2volts, dual battery series that would be 6.4 (3.2x2), I used 3.3 per battery for my watts formula
(150watts/6.6v)=22.7272/0.9=25.25252525amps needed
