Vamo 5 question here.

[Recycled Roadkill]

I looked at a Vamo 5 kit today. My concern is that, while the battery extensions included will accommodate a 18650 battery, two 18350 batteries are included with the kit.

It seems to me that this might encourage someone to stack both batteries the first time around.

I've heard of stacking batteries and understand the rules concerning them. That's not what this inquire is about. Stacked batteries will double the voltage to the circuitry.

Could this damage the circuit board? I've always heard the "rule of thumb" is + or - 10% is considered safe. Most electronics that you'd double the voltage to would instantly fry.

The only advantage I see to stacking batteries is doubling the mah capacity.

I have a Vamo V5 and yes, they actually do say you can stack 2x18350s in the unit if you like. I guess the chip they use makes it safe somehow (or so they say), I don't do it myself. I prefer to run my Vamo is 18350 mode.

Stacking(series) of batteries will double the voltage and the capacity remains the same. Batteries in paralell will increase the total capacity and the voltage will remain the same. Serial and Parallel Battery Configurations and Information
In the case of the Vamo V5 you really need to use the 2 18350 cells to get the full potential out of the mod. There are a few good reviews on youtube with charts and such showing this.

Yes it does run fine in 18650 mode. I use mine that way all the time.

 

[MrSelf Destruct]

When I used a vamo I tried stacking 18350's but ended up going back to using 18650s...the only reason was I only had two 18350's and one of them died.

 

[jmur]

I'll stick with the 650's. Does the job for me and keeps me happy.

 

[jmur]

And ain't that what it's all about?

 

[Bunnykiller]

The Vamo is made to handle both 650 single and 350 stacked.... 5 amps current is the limit for the chip tho...

In my V3 you could stack batteries without an issue, and from what I understand the boards are the same. You can buy more extension tunes to stack two 18650s if you wanted.

That would be one long mod

 

[coalyard]

Vamo will run stacked 350's. Just double check and make sure you are installing them correctly *every time*. I do this with both my SVD and VMAX. Stacked 350's last all day, and well into the next.

And yes, it would make the Vamo long. The SVD is almost a foot of fun with a KFL on it...

Also, I broke my VAMO when I stacked two button top 18350s in it. Be sure to find some flat top 350s or maybe cut a coil off of the battery spring. Not much but enough that the batteries don't push the PCB up.

What's the difference between using 1 18650 battery and 2 18350 batterys to get the "full potential"?

(2) 18350's will perform better in a regulated device. Depending on the regulation, the duty cycle to hit the desired voltage will be shorter with (2) 18350 stacked batteries. They also at full charge, will show a voltage of ~8.4V and drop off to ~7.2V when most regulated devices will no longer fire them. The 18650 battery will be ~4.2V at full charge, and fall off from there.

Without getting pretty deep into Ohms law, it's pretty difficult to explain. Watch the PBusardo review of the SVD or Vamo on YouTube. He hooks the devices to an oscilliscope to test outputs and duty cycles with different battery configurations.

What it means in simple terms is that when I am going to be out for a long day, I have my SVD along with me, with (2) 18350 batteries in it. It lasts well over a day and a half with steady vaping. The VTR with one 18650 is pretty good, but 8 hours is pushing it.

I use my Vamo V5 all the time but in 18350 mode, used to run it in 18650 but tried it one day in the smaller mode and haven't been able to go back. Just a nice size the way it is now.

I don't understand how 2 x 800mah batteries could outlast 1 x 2250mah battery. I have never seen an 18350 with a higher mah then 800 but now you can find 650s up at 2600 I think. I don't get it, how could it be?

I've heard of 18350 batteries that exceed 1000 mah but have never seen them. The Vamo V5 currently comes with 2 IMR 900 mah 18350s.

 

[Recycled Roadkill]

And, wouldn't you know it, I take a glance at the FastTech site and there's 2 18350 batteries at 1200 mah.... but they're ultrafire. Ugh!

I use two 18350 AW button top batteries in my Vamo V5 everyday without a problem.

And I agree with what others have stated, that (2) 18350's provides more accurate power output and fully utilizes the Vamo's power potential in comparison to one 18650. Always make sure to rotate the order of the batteries and use matched pairs.

Don't cut the spring unless you plan to only run stacked 350's. In my V5, the stacked 350 take more room than a single 650. Need all the spring to contact the 650. I use flat tops in both configuration.
