handmade vv mod battery question (smartvapes altoid VV)

[patch]

does anyone out there have any experience with batteries and this type of handmade mod? it runs on two 18650s.

is it safer to use the newer AW IMR 18650 3.7v 2000mAh batteries or should i stick to the older AW IMR 18650 3.7V 1600mah batteries? should I go with these safe chemistry batteries or should i go with ones with a protected circuit?

i have these concerns because of a comment i saw from steeljan in the comments of the youtube video: "One tiny note, you said that AW IMR batteries are protected. IMR batteries are not protected. If your mod gets a short, if you screw a cartomizer down too hard and short the connector, etc, IMR batteries will self-destruct, releasing all their current and a lot of heat pretty quickly.  I would only use IMR batteries in a mod that is designed for them, providing short circuit and under-volting protection."

Hi Patch, Good Question. Are you electrically savvy at all? If you have a handle on soldering small componants then you Could add a simple 10A/15A small (ATM Type) fuse to your battery circuit to protect yourself and your mod against a short circuit. The altoids boxes are rather roomy so you may find enough realestate to add a bit of extra safety. But its a question of personal taste as well so everyone will have a different opinion. I dont own one of these mods so you will have to be the judge once you have it in hand.

If you aren't comfortable with adding extra protection then I would say for safety sake stick with a protected cell. It is after all a metal box and with a pair of 18650 you are packing a bunch of current, and when in use it willl be close to your face. I currently use protected batteries in my mod. I have been considering upgrading to the IMR batteries personally but I would have to engineer a new enclosure with more room to accomidate the protection for me to feel comfortable with the upgrade. I may in time do the upgrade but it will have at minimum a fuse so that I can feel ok with all that extra current sitting in my pocket. Good Luck. Happy Vaping.

I was just fortunate enough to get a Smartvapes Altoids tin and love it. I run the gray Panasonic 18650's they sell for 7.99 a pop. I get about 4-5 days vaping it in the mix with 2 other devices. I'm pretty sure the Panasonics ARE protected. I read a datasheet somewhere that mentioned an IC inside them.

If you are still nervous about battery safety, there is a new fuse product out that you stack on top of the battery when you put it in the clip.

Also, depending on what type of regulator Caged uses for the device, it may have overcurrent, and undervoltage protection built in. That might be something to ask Smartvapes.

Why don't you just use protected batteries? What are you vaping (what ohm atty/carto?). Plus you get more maH. However, you need to compute max amp drain and we can't do that unless we know the volts and ohms. Are you using DCCs?

Anyway, from a battery perspective it should still be fine with decent quality protected 18650 Li-Ion batteries I would think. I'd be more interested to know what the device electronics are rated for. Does it hold up to a 1.6 ohm DCC at, say, 5 volts (3.125 amps, 15.625 watts)?
