Single battery in dual parallel box mod?

[Torq]

My unregulated box mod fires even though there is only one battery in the sled. Is this safe? Will it ruin the batteries?

Like most things in vaping, it depends.  Use Ohm's law to calculate how much draw you are pulling from your battery, and if is below the CDR (Continuous Discharge Rate) you will be fine.

Here is an example:

If you atomizer is .5 ohms and your battery is fully charged you will be putting 35 watts to the coil, and drawing 8 amps from the battery.  If you are running a 20 watt or better battery you will be fine.

Don't go by the numbers written on the battery to determine what it's CDR is, most are wrong.  Also don't take anyone at a vape shop, or forums word for what the capacity, only trust the testers.  Here is a link to the best battery guy in the vape world: Mooch's blog - picking a safe battery.

Another thing that worries me is if your battery will be able to move only running one battery.  If it flops around it could short on something in the box and it could be disastrous.  You should not put a dead battery with a good one to fill the space as it will cause even more problems.

 

CAUTION! unsolicited advice follows:

Save up some money, and pick up a good regulated dual 18650 mod and a couple new batteries from LG, HG, or Samsung.  Good mods can be bought for less than $50 and batteries around $7/each.  You will be much more happy with the additional power and stability of a regulated mod, and you will be much safer at the same time.
