I guess I am not the guy to ask ,I cannot tell much difference ,I use 302's ,510's and 901's and they all seem pretty much the same to me except the carts last longer on the 302's.I for sure don't like above four volts vaping .I guess I would just say the monster batteries are just like always having a fresh battery or being on a Kissbox passthrough.I could go most of the day on a single 10440 and all day on one of my double 10440's.
