This is in regards to when I need to purchase new batteries for my Vamo V3. I'm planning ahead because FT is known for slow orders with batteries and was just going to add to my wish list so I wouldn't forget. The batteries that came with it were Sony US18650V3 18650 3.7V 2150mAh Rechargeable Li-Ion Battery (2-Pack) Those have a discharge rate of 10A.

I see a lot of good reviews of Sony US18650VTC3 18650 1600mAh 3.7V Rechargeable Li-ion Batteries (2-Pack) . Those of a discharge rate of 30A but the mAh has dropped from 2150 to 1600 mAh.

Assuming same attomizer, juice, voltage etc...I assume the 2150 mAh will last longer. What's the advantage to having the higher discharge rate? Doesn't the circuitry in the vamo regulate the current coming from the battery? I'm assuming by using capacitors to store the extra electricity when needed?

Side Note: I originally bought Panasonic CGR18650CG 18650 2200mAh Protected Rechargeable Lithium Batteries (2-Pack) which are protected and I didn't know any better at the time. They are working for me just a tight fit. Whats the discharge on those and since those are protected does that mean if I crank my volts although up it's not really able to deliver that? I usually have it low to middle setting otherwise I just get burnt taste.

Batteries are basically designed for higher amps (reserve power) or higher mAh capacity (battery duration). It's either one or the other, or somewhere in between.

As you noted, the 10 amp Sony's will have more battery mAh capacity which allow them to last longer between charges than the 30 amp version.

However, in applications such as using sub-ohm coils which require a much higher amp reserve, the 30 amp Sony's are the better choice.

I was not able to find any specifications on the protected Panasonics.

so for my 1.6 - 3.0 ohm atties I should just go for the 10 amp discharge with the higher mAh? Don't think I can use anything below 1.5 on my vamo anyway.

So your basically saying the 30 amp discharge is more mech mods and low resistance atties?

As for the protected panasonics I was under the understanding that if I set my volts real high that they battery may not be able to deliver that quickly enough because of the protection in the battery...again I don't really ever go that high usually somewhere in the low to mid settings. And that I don't need protected ones because that's part of circuitry in the vamo.

The protection circuitry in the processors of some regulated mods may see the protection circuit built into ICR batteries as a short and refuse to fire. And with those regulated mods that will fire an ICR battery, the pulse width modulation of the boost circuitry will double the normal amperage of the set voltage because of the way PWM works. This may well be higher than the amp limit of the ICR battery, and the battery will either shut down or not be able to supply what it doesn't have and stress the battery to fail.

Therefore, high drain IMR or hybrid batteries are the best choice for regulated mods.

Why High Drain Batteries?

Am aware of that now...just wasn't when I purchased my vamo a month or so ago. They work for me though so going to use them until I need to replace with the high drain IMR or hybrid.
