need help with resistance

[anonyvape]

got the hellvape passage dual coil rda what would be the best resistance of coils to buy that i can use at a high wattage as i know it halves the resistance for example when you use 2 0.4 coils it would be a resistance of 0.2ohms

It's more a question of what mod will you be using to power your RDA. If you are using a regulated, dual battery device then you just need to keep the combined resistance above the minimum that your mod can fire (typically .05 to .1 ohms) If you are using a single battery regulated device then you should try and keep the combined resistance a little higher to reduce the likely overall current flow required to achieve your desired wattage. I am assuming by your question that you aren't an experienced user and so should steer well clear of using a mech mod (unregulated device)

A lower combined resistance will typically result in a higher current flow which will typically mean your coils will tend to heat up quicker and give you more instant vapour. High resistance will require more power to get a similar response whilst the coils will tend to dissipate heat more slowly and cause more heat build up and an overall hotter device.
