The Tfv4 tank i use with TF-T8 .16ohm Octuple Claptons with a 180W max but stated 140W ideal wattage. It's perfect at 141W and if I use the Koopor Primus 300 with Sony VTC5A 2600mAH 25 amp 3x18650s, the ohms calc. Says 26.6 amps is the current so I'll need 3 pink LG HB6's for 200W style vaping. I think the pink wrapped LG HB6 18650 is the most powerful albeit short lived, 30 amp or maybe more amperage, potentially. 1500mAH in a triple box mod lasts long enough when I used HB4 30amp 1500mAH. The HB6 is the safest high wattage low resistance vaping batteries. LG HB2's are slightly known to last longest but HB4 and HB6 pinks are the best 5 bucks per battery. Anyway, can I vape 140W .16ohm with VTC5A 25AMP 2600MAH? That 2600mah and lasting voltage is so desirable. I use those coils on a DNA200 25amp 1300mah lipo Hcigar VT200 mod. Is it safe if i am recommended 26.5amps and use 25amps?
