Total noob question the nova plays well with any battery as long as you pick or wrap the right coil
2.4 is a universal coil
1.8 on weak
batteries
3.2v--3.7v
2.8 on a monster
@4.8 setting on a twist it blows through the coil and burns the wick
4.2 awesome vapor
if you need to change the resistance just play with the
coils a bit
you can get + - ohms if you move them around
while on a meter
it will test your
batteries build
good luck, its a post direct short
looking for weakest link
if it's your battery setup you will find out
