Batteries

[grob1963]

Hoping some of the vets can give advice on batteries, I have a Vamo V3 and a INNOKIN iTaste SVD Telescoping on the way, I have read lots of conflicting info on the batteries some say better to use just one 18350 while others say to stack the 18350's for better performance and others say never stack the batteries so what the opinion of the vets here? I will use the 18650 battery as well but my question is on the single or stacked 18350

I'd honestly recommend not stacking batteries. If you do stack batteries, make sure you have a kick properly installed. I wouldn't ever stack batteries in a fully regulated mod.

Thank you suspectK, just wasn't sure and wanted to reach out to someone who has a lot more info on this than I do as this will be my first time using a set up like this I currently use a Itaste VV VW 3 and it works well for the office and travel but battery life is not so good

I wouldnt stack 350's or even use them period ,Id stick with 18650's ,not sure stacked batts and a kick would fit

You can stack batteries (I occasionally do in my Vamo) BUT there are many safeguards you should follow.

Stacking batteries is unsafe. Or, I should say it's not the safest use of them in high drain devices like APV's. The Vamo has redundant circuitry in it to prevent short circuits and it monitors temperature in the device. If battery problems occur, the device shuts itself off.

However, that circuitry is not the world's finest, most expensive or most reliable.

What can happen is that you stack two batteries with different charge states and different actual capacities. The one with the greater charge remaining can attempt to charge the other, which can cause either to go into thermal runaway. One going thermal means both batteries go thermal and a potential catastrophe can occur inside that sealed metal tube.

The two grey 800mAh 18350 batteries that come in some Vamo kits are risky for use in standalone mode and should never be stacked. Those are unprotected ICR cells and have an unsafe chemistry. While the Vamo has the circuitry to prevent most incidents from getting out of hand, you are again back to trusting cheap electronics to prevent personal injury or property damage due to a fire or an explosion.

You should get high quality batteries. AW IMR's are the best available in 18350 configuration. Efest also makes decent 18350's. Those are the ones you want, but I wouldn't stack those, either.

Sorry, for some reason I thought the SVD was a mechanical..der.

With my Vamo V2 I saw now benefit from stacking over using an 18650.

One going thermal means both batteries go thermal and a potential catastrophe can occur inside that sealed metal tube.

Even if the battery doesn't go thermal in the pv it can be damaged to the point where charging can cause a thermal runaway.

Take a new pair of batteries and always use that pair together. Check the charge on both of them every time you take them off the charger, check them every time you put them on a charger to be sure they are discharging at the same rate. If they aren't discharging at the same rate then something is happening with the chemistry of one or both batteries and you need a new pair. Do all of this and it it may be reasonably safe but still not as safe as a single battery.

Seems like an awful lot of effort to me.

High drain, safe chemistry (IMR) 18650's would be what I'd use, and AW makes the best, in my opinion. The worst are the no label and EH branded ones in my experience - shortest vaping time and battery life.

Yes you can stack them in a Vamo V3, the circuitry can handle it...I recommend heading over and reading up on batteries alot of great info, one thing to remember, keep the batteries as a mated pair..so this way they charge and discharge evenly

Just to be clear, you wouldn't put a Kick in a regulated mod, only a mechanical mod.

The Vamo or iTaste SVD very well might accept stacking two smaller batteries instead of one larger battery, but for what gain? It will not give any longer battery time, only more voltage. And you can't take advantage of more voltage in a regulated mod unless it was specifically and inherently designed to use stacked batteries.

It's always preferred to use one larger battery over two smaller ones.

I don't have a Vamo but do have a SVD. I have AW 350s and Panasonic NCR18650PDs.

The SVD eats the AW 350s for a snack. The electronics in it must soak up their energy because it drains it fast. The flip side about 1.5 hours to charge.

I really like my Panasonics. Again I thought they would last longer, but they last a sufficient amount of time. Around a 5 hour charge depending on how low I let them get.

I haven't tried to stack... It seems too much of a hassle to keep track of the batteries if you are going to do it correctly. In a regulated VW/VV type mod I don't see the difference in 10 watts with a single battery or 10 watts with a stacked setup (The SVD shows it as 3.2V to 4.5V single and 4.6V to 9V stacked). I barely go above 8 watts usually 7.5 watts.

Going to add.. Every one is going to tell what they like or what you should get (If you were them). What you like vs what another likes can be completely different. In everything from liquid to form factor to quality to metal and delivery device. I am of the mind when I smoked I flipped the .... on the ground and squished it with my shoe or twist flipped the ash on the ground and tossed it in the trash.

Glad to know this info since i'm thinking to buy a Innokin SVD...
