18500 efest purple 1000mah flat top (quoting 15A on battery)

Be a great to have an easy reference guide Ripshod for our batteries...interweb is a minefield sometimes for information like this

I can't say whether some of these are any good maybe Ripshod can but after some research I would probably feel comfortable buying any of them unless someone says different. I guess if they get on the list they're good to go.

I like the Keeppowers myself, mainly because Panasonic like them.

Good to have some 26650s too, thank you @jc72

No problem mate I'm planning on getting a dual 26650 mosfet switch box so was looking into them anyway. I think it's a great idea this thread because it's really confusing looking for batteries when you first start.

Great thread; thank you for doing this. And great to see the Samsung 25R's on the list, having just bought 2 earlier today, lol. Phew.

[Ripshod]

Some peeps are already checking this thread, so a quick list of my top 18650s and 18500s, listed by power (regulated mods) and ohms (mechs). It's untidy, it's still being built, but there's no errors. There will be more batteries added as I get to them so keep suggesting new ones.

18650:

75Watts / >0.14Ohms - Sony VTC5, VTC4, VTC3 / Nitecore NI18650A / Torchy 30Amp 2500mAh / Solotech 30Amp 2100MAH

60Watts / >0.175Ohms - AW IMR18650 1600mAh

50Watts / >0.21Ohms - AWT 35Amp 2500mAh / Efest Purple 35Amp 2400mAh / Efest Purple 38Amp 2100mAh / LG HE2 and HE4 / Samsung 20R and 25R (Grren & Blue) / AW IMR18650 2200mAh / JacVapour IMR18650 2500mAh / IMREN 38Amp 2600mAh / IMREN 40Amp 2500mAh / Keeppower IMR18650 2500mAh

25Watts / >0.42Ohms - AW IMR18650 2000 mAh / Panasonic CGR18650CH


18500:

45Watts / >0.24Ohms - AW IMR 18500 1200 mAh (red)

37.5Watts / >0.28Ohms - eFest IMR18500 1000mAh (red)

25Watts / >0.42Ohms - JacVapour 1100mAh / Keeppower 1100 mAh / eFest 1100 mAh (red) (flat or button)

22Watts / >0.48 Ohms - AW IMR18490 1100mAh


18350:

30Watts / >0.35Ohms - AW IMR18350 800 mAh

Thats Good Work Ripshod.
Like that you are listing The Power and resistance capabilities of each battery.
Am i right in saying you've accounted for some 'headroom' so that the battery is not stressing to much?

I have for regulated mods. I don't think headroom for mechs is too important with the batteries listed so far - as soon as ypu fire a low ohm coil the battery's volts will immediately drop, kind of giving it's own headroom. You have a concern? Better to discuss it here

[hijack]

I was just glancing at the numbers and roughly doing the math in head and thinking with the VTC 5 that 30A would allow lower. But if your factoring in a decent margin 1st then it looks good.
I was just curious about the margin if any that you had given.

[Ripshod]

Questions are good. TBH I'm surprised we haven't had a load more hijack
Some will see this effort as me laying the law down, when the law is already written.

[Ripshod]

Using pure maths a VTC5/4/3 would be capable of over 100Watts, but we have to take into consideration the IR of the battery and the joints/wires within the mod.

A simple method for regulated mods is to consider the battery's voltage as 2.5Volts. This will allow for battery drain and Volt drops.

so - 30x2.5 = 75Watts (2.5Volts takes into consideration a drained battery and the Volt drop)

I'm not intending to treat anyone as dumb, just taking the maths out of it all to make it easier to get the head around

You have to admit hijack, as rated outputs of batteries get higher the IR becomes all the more important (especially with one company pushing a 20Amp (quoted 35Amp) battery with an IR of less that 0.08Ohms (DC)). Using V=IR we see that 20x0.08=1.6Volts. A freshly charged battery could easily drop to 2.6Volts when fired.

The offender in this case is AWT, but seeing how easy it is to push such batteries is BLOODY FRIGHTENING!!!!!

Yeh after running your numbers on a calc they are bang on the limits of the battery.
I think you know were I'm going.

Is it OK to use batteries to their limits?

We've all seen idiots frying their sony's and melting firing switches on u-tube, by using wire roped together to try a 0.01 coil for the 'crack', so stupidity does live out there (for a while).

You work with electrics and I'm an armature enthusiast, so if you say 'it is so' I will take that as read and will by wiser for it.

[Ripshod]

It's not okay. That's the point.

I want to list batteries that CAN be used at the limits with no harm. Of course there will always be peeps that can fry a VTC5, but with an IR of (typically) 0.013 Ohms it's a whole lot harder to fry a VTC that say a 35Amp 2600mAh (clue there) AWT.

I'm saddened by such batteries being recommended for vapers, when the companies supplying them are only interested in profit (I recall I mention this elsewhere on the forum).

We can't advise 'idiots' but we have to be careful how we label peeps as such. At the end of the day they are only going on the information provided by peeps such as you and me.

And so I stand up and speak!! There isn't a single battery in my 18650 list that has an IR(DC) over 0.025 Ohms (rated and tested). That includes all the relables

I was unaware of the 2.5v formula to use with regulated mods and was looking at it from a mechanical side using 4.2v as I live in the 'Dark Ages', where Setting 75w and setting temperature is 'Black Magic' and 'Wizardry'.
