Seems windyfire it’s a “fire” brand with little to nothing to share with other “xxxfire” brands

Their imr i’ve tested till Now are very good, with a nice price/performance ratio

What do you think HkJ?

They do have some good batteries. I wonder if all the batteries I got from them are just as good.

I would like to try some of the good ones for obvious reasons suchas price. But, I have been afraid to order them and have stuck with Efest, Keeppower and Olight. I use 18650’s, 18350’s and would like some 16340’s.

Advice please?

Thanks Matt

I just realized these are LIFePo4 chemistry. I guess you can’t get a safer cell than that. Very nice and thanks for the review.

No. They are probably IMR chemistry, i.e. LiMn.

Hi HKJ,

I got this directly from the WindyFire website. Assuming you are correct, it’s amazing the manufacturer mis-labled their own product.

They must have mislabelled it. It is definitely not LiFePo4.

If we thought there wouldn’t be yet another xxxfire, out comes Windyfire! Surely people can come up with unique names.

Having said that the performance comes up well in your review. Thanks again HKJ for the review.

Thanks for the review HKJ.

You will like them. I bought 2 from Mt. Elec. for my Modded Minicree[Sipik]. They provide plenty of output[~700 lumens/80Kcd] and decent run time. Wink

Hi wolfdog1226 ,nice to meet you here.
may i ask you one question ,Based on my experience,the minicree flashlight Conventional drive current is generally 0.5A,windyfire 14500 battery the discharge is 10A,the li-ion 14500 Usually have 2-4A discharge ,so the IMR 14500 and the li-ion 14500 all can Can meet the driving current ,In theory is the same output, I do not know how is the Real world ,
wolfdog1226 ,do you have some experience.

For a stock light you’d be correct but some of us have modified lights that run on a 14500 and pull over 5 amps.

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.

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.

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.  

Mountain Electronics : batteries, Noctigon, and much more! What's new?
