Hello. Currently i am using RX2/3 in dual battery mode with Velocity V2 rda at 75w and 0.22ohm coils. After 3 days ill get TFV8 and i think ill be vaping it around 120w on the RBA section. I have two married Sony VTC4 batteries. And it shows that it is drawing 17.6amps, but battery life is short, i want longer battery life. So i am planning on getting three LG HG2's but those are 20amp batteries, and as i will probably wape at 120 watts i want to get longer battery life, but is it safe with LG HG2's? if i vape my current setup at 120w and 0.22ohm coils it shows that i am pulling 22.4amps out of batteries, and if i have LG HG2 it is 2.4amps above its limits. So is it safe to wape at around 120watts at 0.2 ohm coils with three LG HG2 I am sorry if i cant explain everything correctly, my english is kinda bad, and i also dont understand all this amp, wattage and ohms well.
