I saw “Thorfires famous “happy” boxes”, and I had to laugh.
Do you have a light capable of pulling a good draw, and another battery to judge by? I’m curious as to what a protected battery is actually able to pull. My only 26650 lights are 3 amps or less, so any battery is likely capable of that. I do know with their protected 18650’s, I get a solid Amp less on a Fet, than I do with a Hotrod Battery. I’m talking 5 amps or less.
It’s good to see that they aren’t over inflating their capacity. 5000 Mah is huge. I’ve had good luck with their batteries, though I still have to question re-labeling. They could change at any time, and who’s to know. Typical Chinese business ethics. I believe their original battery labeling was Eashine.
I have run the Thorfire 5000mah cells in an S70 (my highest drain light) & also my Keeppower 5200 mah cells & couldn”t notice any difference…
The Thorefires ran the S70 on Turbo fine.
I ran it on turbo with the Thorfires, probably 10 times switching back to turbo immediately each time it stepped down to high (3 minutes) with no problems.
Took the cells out & they were cool.
Amazon UK had a deal (only lasted 1 day) if you bought the Thorfire 18650 motion sensing headlamp you could buy Thorfire cells half price (there haven”t been any 26650 Thorfires on Amazon UK since).
I bought 2 of the headlamps & a pair of the 26650 cells.
Any idea if the protection in these cells can be considered safe like with the more expensive brands?
And do you have any way to test the max continous current draw?
No idea as I only have items that draw a max of 6.5A, which they obviously handle fine.
Thorfire told me (I contacted them direct) that continuous max draw was 10A ?
I did intend to test them to see when protection kicks in but this will only tell me the voltage this happens at as the only way I have to do this is to use a device with a constant draw until the PCB trips.
BTW I am only using these Thorfire cells in a light that has a mode switch that changes colour to warn for low battery voltage (green, orange,red), has low voltage warning (light flashes) & low voltage cut off so I am not really to concerned.
My Thorfire 26650”s are definitely 66.6mm long, I have just remeasured them.
I do not have an L6 so can”t comment if they will fit but power wise they should be fine for the L6 as I am running them in an S70 which has very similar power needs to the L6.
I haven”t tested whether they are protected but Thorfire confirmed via email that they definitely were & they don”t seem like the sort of company that lies.
Even so I am running them in a light that has visible battery status via an illuminated switch that changes colour (green, orange, red) has low voltage warning & low voltage cut off so personally am not worried if they are unprotected.
All my other 26650”s are unprotected anyway.
They’ve already lied that they manufacture cells - they don’t - it is cell made in Taiwan and not by Thorfire.
Protected cells are much longer you can compare them.
5000mAh bare cell is longer then smaller capacity cells even without protection.
Quick check for brave guys :
Piece of wire
Short the cell for 1 sec
See if DMM reads zero volts after you shorted your cell(that means that protection kicked in and circuit is open)
With protection cell will not have time to heat up so no risk of some damages.
If it reads zero volts place it in your charger it should have “soft” start, and circuit will close again. All good.
I am not arguing with you & am only stating what Thorfire advertise & backed up by email when I specifically asked them about the cell.
I did mention in a previous post that I was surprised how short the cell was considering it was claimed to be protected.
However the cells tested well against my Keeppower, Basen & Liitokala 26650”s (all unprotected) on my analysing charger in terms of capacity & IR & perform fine in the flash light (which has lots of protection/warnings built in) so I am really not concerned.
Thorfire had a 1 day sale on Amazon UK.
If you bought one of their 18650 motion sensing head lamps you could buy any pair of their 14500, 18650 or 26650 cells half price, that is how I got them so cheap.
I use these thorfire cells in my s70 and plan on using them in the l6 when it lands this week. Haven’t had any issues with them and honestly I’ll probably by more of them next time im shopping on Amazon. Takes awhile to charge back up but I’m using xtar vc2. But I’d rather slow charge my cells and get more useful life. I have another set to switch them out with and like 16 18650s. The lg hg2 work well in the s70 but with 3000 mah it goes in turbo. Panasonic 18650b is a really bad fit light ran but had to keep adjusting tailcap hg2, and 30q had no problems
I can vouch for these batteries, using them in my L6 right now with no problems. Tested capacity at 5148 and 5276 @ 4.21v. Better than my AWT 26650 “4500mah”, i tested these at around 3700 to 3800mah @ 4.21v (I think there are same as efest re wraps). I like these Thorfire guys, they warrantied a light I bought of Amazon after the 30day period (it was actually 3 months after I bought it) and it came from a West coast warehouse in 4 days. They asked me to do a amazon review, I refused but still got the light!
