Hey, I just bought a sigelei 150w and a Dark Horse rda about a month ago on eBay, and some new batteries for it from a vape shop. Since then, I notice that whenever he battery reader reaches around 60%, the "check battery" reader comes on and won't let me vape it. It may let me continue for a few more hits, then it comes on again. If I take the rda off and put it back on, it may let me vape it for a few more hits, then do the same. I was wondering if it sounds like my mod is defective, or my rda, or my batteries? I would contact one of the companies, but I don't know which part is messing up. By the way I vape it on 50-65 watts usually. Thank you for your help in advance.

People are suggesting the illumn.com Samsung 25R's for $5 - get them! Sounds like the batteries aren't staying around the 3.7V that the Sigelei needs to fire above the nominal voltage of each battery.

This could be because one of the batteries is damaged or otherwise faulty, or because the battery is counterfeit. Either way, I wouldn't use those batteries you have inside your box anymore.

Something's fishy about them. My Sigelei 150 fires until the batteries dip below 3.7V - around 40% and below.

The batteries I use are married and I use and charge them together. And thanks, I'll check the illumn.com Samsung batteries out. And I use an intellicharger i2 charger. Is that good? And I planned on getting a new charger soon anyway so I'll check those out too

But I guess since everyone is saying something about the batteries, this means my mod isn't defective?

I would definitely change out those batteries, something isn't right. Personally I stick to the Samsung 25r or the LG HE4. If a company doesn't make the battery themselves (very few do) then it is a re-wrap of something. Why buy a re-wrap when you can buy batteries produced and labeled by the manufacturer themselves.

If you are in the market for a charger, I have been using the XTAR VC2 and have been very happy with it.

You need some type of volt meter to know the condition of your batteries and the charge level before you can pinpoint the problem. It could be the mod, it could be the batteries. You won't know until you know the battery voltage individually. The Samsung 25rs are 2 for ten bucks on ebay and the d2 charger which has an lcd display for voltage is 16 bucks. Totally worth it. Your batteries could be fine, but we don't know if we don't know the voltage.

MXJO batteries. How can I tell if they're fake?? I'd hate if they were, the vape shop charged me 30 bucks for 2..

These aren't popular batteries. I doubt that MXJO actually manufactures their batteries, they are likely re-wrapps of some other company's cell. I can guarantee that they are not a true 35 amp battery. You definitely overpaid for them at your vape shop.

Get some AW, LG, Samsung, Sony's, or Orbtronic batteries.

Good choice! I'm guessing one of your batteries is losing voltage quicker than another. Since they are rewrapped, you don't even know if they are the same battery, they could have different specs. You always want to make sure you are using 2 of the same batteries when you are draining them as fast as these mods do. It's not a typical scenario like a remote control or something like that.

I can't tell you, I don't know what they are. That's the problem with rewraps. You want to buy direct from the source, not the cheapest option that companies put their name on. I would just use caution. Maybe vape at a lower wattage and make sure they aren't getting hot, and charge them when your device tells you to instead of unscrewing or resetting the mod.

MXJO's are rewraps. I would suggest avoiding them.

Also, 15$ per battery is overpriced for any cell, let alone a rewrap.

Among other things (worth mentioning) the Sig150's battery reader is pretty wonky. I recommend taking your batteries out to charge them when the meter hits 50%, as that leaves them with about 3.5V. Draining below that voltage potentially decreases the long-term lifespan of your battery.

Oh and as another member mentioned, make sure you're marrying your batteries if you're using them in a dual-battery box mod. Once you use them in that box, they cannot go in any other single-battery device. They have to be charged simultaneously and must be put into the box when they're BOTH fully charged. It's very, very important.

Just out of curiousity and for bettering my knowledge,why do the batteries I put in a dual battery box mod have to be married, and why can't I put one in a single battery device? What would happen if I did? Would it damage the mod or something? Thank you

It could potentially result in a catastrophic failure, it is a huge deal that batteries in series have matching nominal voltage when they're put in a device.

So let's say you've got 2 batteries and you've been using them in your dual battery mod since you bought them. Those batteries have virtually identical wear and tear, they've been through the same number of charges, their voltages should drain at identical rates in your device. This is what you want.

Let's say for example you pull one battery out of your sig, and throw it in your mech for a while, and then pop it back in your sig. Uh oh. Now one battery might have 4.2V nominal voltage (the one that you didn't pull) and the one that you used in your mech is now down to 3.6V. One battery will see its brother with low voltage and say, "hey, let's even ourselves out" and potentially (though I hope the circuitry in protected devices would prevent it) dump its voltage to its less-charged brother in a VERY short period of time, likely exceeding the CDR of both batteries. The result, in this worst-case-scenario, will be thermal runaway, and it won't be pretty.

Again, hopefully the circuitry in devices like the sigelei150 will prevent batteries "loaning" voltage in the event that they're unmarried (and I suspect they do), but I am not about to leave something like that up to chance.

In a dual-battery series mod with no protection, I doubt there would be anything to stop your batteries from venting in your device if you used unmarried batteries with drastically different nominal voltages.

I'm not 100% sure, as the intricacies of parallel batteries confuse me, but batteries in parallel don't actually need to be married. In fact, I think a dual-battery parallel mod will work with 1 battery.

Hope that helps, and I'm sure someone has some corrections to make on what exactly could go wrong with unmarried batteries (as I've heard different explanations).
