18650 Battery Health Question.

Can I use an external battery pack to charge an IPV Mini?

I have a 10,000mAh external battery to charge my cell phone (Note 4, with a 3500mAh battery), which has 2 options for charging: 1.5v=1A and 2.5v=2.1A.

Is it recommended? Is it safe? Are there any precautions I need to take if I use the battery pack?

I haven't gotten around to getting an extra 18650 battery (and charger) for the IPV Mini. I've finally realized that it takes maybe 2-3 hours to charge the battery via the USB cable. But the one battery doesn't quite last me all day, depending on how heavy I'm using the Mini.

I usually carry a Volcano Inferno once the Mini dies, but the Volcano really sucks in comparison to the Mini. I'd love to be able to charge the Mini while I'm out and about.

I've added a pic of the external battery for specific information.


Thanks for all your help.  

Now that I have gotten into unregulated mods I've been doing a lot of reading about batteries... well actually I had started reading before but now that I am actually using them I want to know more.

One thing I am a little puzzled about is that you should recharge a battery when it's about 2/3 discharged and you should never charge a battery that is completely discharged. My questions:

1. How do I know the level of discharge in my battery? - I don't own a multi meter
2. What do you do with a fully discharged battery? - just chuck it?  

Hi

I'm using Samsung 21700 T40 batteries.
Trying to figure out..
Is it best to charge a battery when it's discharged or nearly discharged?

I like to keep things simple with a routine of charging once a day, but then the battery will be set to charge even when there's 15-30% power left.

Is that bad for the battery?  

Hey guys,

I finally updated my charger a few days ago (I think before I had the VP2) or something like that. Quick question on something I'm noticing that seems a bit odd to me.

When I charge (for example 18650's), a battery that's fully charged in channel 1...it flashes FULL/0.00 mA, I remove the battery. A few minutes later, I'll put the battery back in the same bay, and all of a sudden there are a few hundred mA's that show up on the screen that need to be charged back into the battery and it takes a few minutes for channel 1 to recognize the battery is fully charged and flash FULL/0.00mA again (although it does show above that's fully charged at 4.2v).

If I take that same battery and do the same test but this time in channel 2, within a few seconds it recognizes that the battery is fully charged and flashes FULL/0.00mA. So it seems channel 1 is not working as well as channel 2 is, when it comes to recognizing information from the battery.

Is this normal for this charger or do I have a defective charger?  

So I'm in the market for some high drain 18650 batteries and I was about to go with the Samsung 25R but then I stumbled apon the AWT IMR18650 2600mAh battery. I'm see in some places that this battery have a maximum continuous discharge of 35A and a max discharge of 40. Is this really true? Because I'm also seeing in some other places that it has a maximum continuous discharge of 20A and maximum discharge of 40A (which seems to be a bit more believable to me). If anyone has a link to some testing done on these it would be greatly appreciated. Thanks!

Here's a link to FastTech's listing where I originally found out of this battery: https://www.fasttech.com/products/2287804

And a Ebay listing saying it has a Max. Continuous of 35A: 2 PC AWT IMR 18650 Li MN Battery High Drain Rechargeable 3 7V 2600mAh 40A Yel | eBay  

I got a problem with my Luxotic Surface. I'm using a LG Choco Battery 18650, it was fully charged and when I press the fire button suddenly it appears for Battery Low even the battery was on fully charged. I tried my spare battery maybe its just a mistake putting a fully charge battery, but it was the same issue also with the spare battery. I tried the 2 batteries with my Geek Vape Aegis 100W to check whether my batteries are already broke but it works fine. I was vaping for my Luxotic Surface by 55.0 Wattage, 0.21 ohms, 3.40 Voltage. Can someone help me out to fix this problem?  

A long time ago, talking to a friend who's an electronic engeneer, he advised me to do something and so far works beautifully. It's specially true of cellphones and integrated battery stuff, so you might as well do it to your iSticks and your Kindle as well.

When you receive a new device that has an integrated battery and charger, both have circuitry controlling the charge. The first week of use or so (in the case of the Kindle the first few weeks or months) do complete discharge (until it shuts down completely) and charge completely cycles. This calibrates the battery and the charger to make a more efficient use of the energy.

Just now I'm putting a new iStick 30 though its paces. First day lasted me about 6 hours. Second day almost 8. Yesterday a full 12 hours. Doesn't matter the voltage. Charge it completely and discharge it completely a few times. You'll see how performance increases dramatically.  

i have a new Itaste VV4 15 watt 1000mah
I don't seem to get as much time out of my battery as i expected- does anyone know about how long it should last?

I'm going to test it out to see exactly how much time i get out of a full charge but as of right now i just feel like it's not lasting as long as it should.

Also when I use it plugged up on a charging cord the battery still runs out till it eventually has no charge and turns off and cant be used till it adds up some charge on it- I thought since it was a pass through device i would still be able to continue to use it while being plugged up on the charger, so im not sure if I should actually be able to with this device and mine is not working correctly or thats just how this unit does work.  

I have a variable voltage/wattage battery and I have heard that some say charge it as often as you can this reduces stress, others say that's bad, some say a combination of long and short cycles but I don't know which is best. My battery's manual said get down to 10% but it doesn't measure it accurately (but I love these batteries so I don't want to change but they are expensive so I want to prolong their life span as long as possible even if that does mean charging them very often.) I do have two so charging often isn't an inconvenience for me if that's what I am supposed to do.  

So last night I guess I was more tired than I anticipated and forgot to unplug my charger before knocking out. I was charging a 18350 battery. As soon as I woke up I remembered and immediately unplugged the charger. I left the battery sitting all day and just checked it on my multimeter and it reads 4.18 volts. I also checked it on my sigelei and it read 4.2 volts. I am th overly cautious type though so I just wanted to ask you guys if you think the battery is still safe or if I should properly dispose of it.
