It’ll get hot after running for a bit, but there’s nothing like pulling out a tiny AA sized light and having huge output for the 30 seconds at a time you need it.
thanks you .Different purposes for flashlight ,so need battery have parameters ,the flashlight some time need light more time ,or some time need More bright .Before i know most people only need flashlight need light more time ,i do not know flashlight need IMR Battery,our company IMR Battery most use for Electronic cigarette.
thanks you information,Thank you for communication.
I’ve used your Windyfire 14500 IMR’s and they are great. I’ll be watching as more sizes of your batteries become readily available and tested by HKJ, and won’t hesitate to buy more.
Notrice I said “Modded”,it is a modified light by Vinh Nguyen. ~ 700 lumens/80Kcd w/ an XPG2 PDTc [dedomed] single mode direct drive.
I have a question for you! How come an order seems to have to be reviewed before i can find out about shipping? I use efest/K’Power/LG/SONY/Samsung IMR Batteries for my Modded M2Xvn . I was going to try one of yours and was not able to order???
Thanks, but availability is the limiting factor right now. I buy batteries from Mountain Electronics, because I trust Richard and his diligence in sourcing good batteries. Right now he only offers the 14500’s. I bought 6 of them a month or two ago.
thanks for your feedback,I will ask some suggestion from Richard,and see if he can provide more types of our battery in order to meet different demand.thanks again.
I've been really impressed with the Windyfire stuff so far--especially since the price is spectacular. Their customer service has also been great so far. I'll get some of these with my next order.
thanks for your interested in Windyfire IMR 18650 battery,May i have a question,what products you will use for the 18650 battery?
still flashlight? the flashlight use one or more battery?
Linda, can you show us any technical information? Are there data sheets or graphs? What chemicals are used? Do HKJ’s measurements agree with measurements your product’s manufacturer makes? What is their main market? What is your job, and who do you work for?
Good day, may i know do you need technical information for which battery? datasheet you can see from the website www.windyfire.com.IMR battery are Li-Mn chemical.HKJ’s measurements are nearly same with ours,now this is most used for
e-cigarette and flashlight. i am as a foreign sales.
Hi wolfdog1226 , i have some qustion about the modified flashlights ,is the three characteristics will affect the brightness of the flashlight? the bulb,the flashlight Drive plate current ,the battery,On the market the CREE LED is most Popular ,I have seen CREE U2 specification ,the max current is 3A ,Theoretically i think ,if the battery have more 3A discharging ,all can get the Maximum Lumens . Is it right?I want to hear what you think.
i have see some flashlight in china ,The torch more lighter, are generally more CREE LED ,like 9 CREE LEDs,15 CREE LEDs.
I am sure there are others who can answer that better than I. Those Gimmick lights[sorry!] w/ 9, 12, or 15 LED’S will only put out an “X” Amount of lumens because the batteries only have so much power!
The link below is an example of getting 15K or 20K lumens w/ 4 or 8 quality 18650 batteries and 7 LEDS,Those gimmick lights could never do that because they are not boosted enough like these modded lights.

Some people do not stay within specifications. Leds can often take considerable over current before they blow, especially if they have lots of cooling.
Recently I tested a driver that could deliver 6A into a 3A XM-L2 led or 9A into a MT-G2 rated at 3A: http://lygte-info.dk/review/DriverTest%20LD2%20UK.html
