Are Efest 35A batteries safe for sub 85 W vaping ?

[Laser Beam]

hi

just bought revenger x 2 weaks ago with 2 Efest 35A purple battries .. i know they are
a rewarp and mabey even 10a batteries .. so i bought samsung 30q form amazone and they
are not even samsung totally fake laptop grade batteries .. for my country it may take 2 or 3
weaks to buy the good stuff from a trusted website .. i dont know right now are efest
35a good and safe for sub 85 w vaping " the 2 batteries not 1 for my mode"

85 watts would, in your mod, require two batteries with 45 watt capability (45W X 2 = 90 watts). Had your Samsung 30Q 15amp (45W each) been authentic, they would have just made the grade.

Since (1) Efest rewraps unknown cells, (2) almost always exaggerate the amp specifications, and (3) can change the cell they use at any given point in time, how can anyone give you an honest answer?

You made two mistakes in buying batteries. You bought Efests, which no one can tell you what specs they really have. And you then bought batteries from Amazon, not a trusted/reliable website to buy batteries from. Maybe you make a better choice third time around.

When doubt, look it up on List of Battery Tests | E-Cigarette Forum .
It looks like yours is mislabeled and is actually only capable of 20A or ~50W.

When choosing batteries for a regulated mod, consider the wattage setting that you will use and choosing batteries by their true amp rating (max. continuous discharge rating).

That is assuming that Efest hasn't changed the cell used since the last time Mooch bench tested them.

 

[bombastinator]

Since you know they’re not 35a batteries and they almost certainly aren’t even 30w batteries the answer in the long term is no. Treating them as 10amp batteries You might be able to get 70w on your two battery mod though. If they’re 15amp you might be ok. If. The problem is they might not even be 10amp. 8amp batteries are made. Or one or both of them may not even have actual batteries in them. There have been reports of battery cases filled with sand for example.

Rewrapping is so evil.

yeah i am aware they are 20A at best but i am conserned if they are 10A .. i know they did this for their
older allged 30 - 25 A stuff .. but id assume efest are decent enough to not rewarp a 10 A cell as 35 A one
ehter way i have to use the mod lol .. its 2 weaks still unused and i think id take the risk until i can buy a vtc5
or 30Q from a trusted site whitch will take a long time for shiping

At the very least, check how warn they are getting. That means pull them out immediately after vaping some. If they are more than a little warm, that's not good news.

 

[Dudeman]

Provided your coil isn't built too low you should be okay. Pay attention to amps if your mod displays it and pay attention to how warm the batteries get. If they don't get much warmer than ambient temp, you're fine.
If your mod is any kind of good and the batteries have too low an output, you should get a "weak battery" warning and/or it will barely give you any power, even with fully charged batteries.

Picked up two revenger's when they first came out both are my main goto devices. One with T1 other with Kanthal A-1 My best performance batteries with both units are my efest 3000 mah 35A with a shiny wrapper out performs have 3 pairs of them one pair Sony left. Also got a pair without the shiny wrap that 3000 mah 35A not as good only one pair.

Coil resistance has nothing to do with Amp rating on a REGULATED mod.


op. You got some crap batteries. I'm sorry it's difficult to get good cells where you are, but please try. I wouldn't even know what you've got, and no one here could. As @Rossum pointed out, if your cells get overly warm when vaping, then discontinue use.

Is it dangerous to use those efests? Probably not, but you'll likely not get the 300 cycle life out of them.

Provided your coil isn't built too low you should be okay.

Coil resistance has essentially no relevance in terms of amp draw from the battery in a regulated mod.

Pay attention to amps if your mod displays

This reading is amps being delivered to the coil, not what is being drawn from the battery.

If your mod is any kind of good and the batteries have too low an output, you should get a "weak battery" warning

Most mods will warn and react to a low voltage state in a battery, not the amp draw.

 

[Rossum]

Most mods will warn and react to a low voltage state in a battery, not the amp draw.

A well-designed regulator board will monitor how much the battery sags under the load that's being pulled at whatever power level it's set fire at. If that sag is excessive, it should warn the user. Some will even back off on the amount of power they'll produce. I cant say whether the board in the OP's mod does this, but Evolv's DNA boards have done this since at least the DNA20.

For safety's sake I always assume an Efest battery, red or purple, is a 10 amp battery. Fine for my lower wattage (<15) applications but nothing else.

 

[Laser Beam]

lolol .. just learned from older topics here you cannot use different batteries for the same mode .. forget about 10 A .. if i have 2 different quality efest cells in my mod i could have a bomb in my hands .. i intended to use them with gt4 coils since they have law watt requirement but i think i'll wait for my q30 shipment
