Battery Paranoia

[DeadLili]

I've been vaping since 2009. Until a few days ago, I was still rocking the ego twist. Being around for the wild west of vaping, watching dumb people use unprotected batteries, and seeing videos of mods exploding in people's hands has made me paranoid.

Now I have a KangerTech Topbox Nano. The manual says, "Cell: Lithium 18650. 3.7V (must discharge over 30A)" Umm.. ok. So I pop off the battery cover to see what the vendor threw in there for me. Turns out it is this one: Sigelei 35A 2500mAh 18650 Bench Test Results...shame on you Sigelei!.

Is this battery unsafe for this mod? Does what mode I run the mod in (TC vs Power) affect which battery would be best for it? The Topbox Nano is 60W max. Any advice on a better choice for battery?

I personally run lg he4 and 35a metallic efest. Check out the battery posts by mooch. He's our battery guru.

TC mode saves energy (compared to power mode at the same wattage), since it will cut off power as soon as the temperature you chose has been achieved.

Thank you. How do I apply the manufacturer's instructions, "must discharge over 30A"? Do I need to pick one from that chart that has an Actual CDR of 30A? What are the consequences of a battery that does not discharge over 30A?

Sorry for all the questions... paranoia. Heh.

Thanks. That makes sense.

The battery will only be an issue if you were to run something like a mechanical mod. You Kanger is electronic and has a lot of built in safety features.

There are also very few high drain batteries that output 30A, but that's ok, because you don't need them. What i would recommend you do is buy some good 20A batteries and the current favourites for various uses are the LG HG2's - that come in an appealing shade of brown!

Yup, LG HG2's would get my vote as well, long runtime and plenty of amperage headroom. Check out RTDVapor to make sure you get authentic batteries and you'll be fine.

Thank you all!

I doubt there are any true 35A 18650's around anywhere. Below is a link to a long list of batteries tested by Mooch. None went to 35A in the tests, despite being manufacturer rated at 35A.

35A would be the maximum load created by using the supplied atomizer at full power. The Kanger Topbox Nano is a 60W device. You aren't likely to get anywhere close to 35A even with the .15 ohm coil in the starter kit with a regulated mod. Looks like the starter kit includes the .15, .5, and 1.5 ohm coils.

You could hit 40A on a mech at 6V on a .15 ohm coil. That would be 40A and 240W at 6V, according to the online Ohms Law Calculator. A regulated mod would downshift to avoid battery overcurrent and would top stop at 60W on your Kanger, according to the specs below.

I think it would be very helpful, if we recommend at least 2-3 batteries and notonly 1. Sometime a certain battery is out-of-Stock, sometime is really expensive, because the availability at a certain time is low.
I would add to the list the following batteries:
1. Samsung INR18650-30Q (pink sleeve)
2. Samsung INR18650-25R (Green Sleeve)
3. Sony US18650VTC5 (Dark Green sleeve)
4. Sanyo UR18650NSX (Red sleeve)

All the above batteries have between 2500 - 3000 mAh and can hold 20A CDR

They are out of stock at RTD, but VapeNW has the LG HG'2's in stock, LG HG2 18650 3000mAh 20A - 35 Amp Peak $7.99
I've personally bought them from there and can assure you they are not fakes.

 

[Mooch]

At 60W that mod is only drawing 60W / 3.2V = About 18.8A, worst case.

You can use any good 20A-rated battery. I recommend the 3000mAh Samsung 30Q or LG HG2 in order to get the longest vaping time before needing to recharge.

 

[DeadLili]

You guys are awesome! Thanks.

I know this was eons ago but I either use lg hg2 or lg he4 for about $5 a pop and I get then from genuinecells who has their own page as well as an eBay store. They've never done me wrong in 2 years
