We are talking about Sony VTC5A 2600mAH, 25 amp 18650's that hit the U.S. market very recently. The Mr. Mooch tested them as they're rated by Sony plus have lasting voltage unlike other high mAH batteries. VTC5 is a 20 amp battery inferior to the VTC4 23 Amp. I have 6 VTC4 23amp 2100mAH cells, 3 pink LG HB6 30amp 1500mah, and 3 Sony VTC5"A" 25 amp 2600mAH (incredible) This is the best battery for most vaping subohm applications. The Koopor Primus 300 mod is actually the only Koopor that rocks. Its heavy but the zinc alloy construction is like from a spaceship. 2 LG HB6 batteries in my Sigelei Fuchai 213 allow for 200W for most time before rechargevis needed. The IPV6x 200W mod and a pair of LG HB6 or HB4 will keep 190W for the entire time. Can't I use VTC5A's for 145W .16ohm 4.3V Vaping?
