On to my second set of cheap Chinese batteries that are giving me 1.5 - 2 hours on starting on high. What would I get out of a decent set of 18650 4 cell batteries? Thinking I'll just keep the cases and swap out the batteries for some Torchy ones if that's possible.
2 hours on full, 4 hours on low with a shagged battery
my battery tests out an actual 2200mah and i get 3 high 5 and a bit low
Great, thanks bud.
I have one of the Torchy Fluxient battery packs (doesn't seem to be selling them at the moment though). I recall it having a larger capacity Samsung batteries?
It did 2 hours on full power & lost 1 blob on the light. I've since got a splitter cable to run 2 lights on one battery & tested that - it seems to be about 1hr 40 mins on max power that can last before the bottom warning light is flashing & the power drops off.
Good batteries.
I ran one as a head torch with the torchy pack (in my back pack) at relentless 24, ran for at least 6 hours on low.. was too knackered to see how many lights were left on when I took it of tho'
Any Cree XM-L based light is likely to be pulling [u]approx[/u] 1000ma from a 7.4V battery [u]per LED[/u] on full power.
You can [u]roughly[/u] approximate battery life by doing:
Battery Capacity (mah) / (1000 x NoOfLeds)
So for a 2 LED light using old magicshine/fluxient 4 cell pack:
4400 / 2000 = [u]approx[/u] 2.2hrs
Pretty sure I read somewhere there's some new 4 cell packs rated to 6400mah, so the best you'd get on 4 cells would be:
6400 / 2000 = [u]approx[/u] 3.2hrs
hunk lee seems to be the place to go for replacement packs now- pretty quick delivery, good range. Seemingly random pricing, I found a high capacity pack for less than the middle of the road ones. Oh, quite short cable though, that's slightly annoying, it's about 3 inches too short to work nicely with my bag/light setup so I need to use an extender
The industry seems to have arbitrarily decided that 4 cells = 4400MAH but it's total bobbins, even within apparently identical products there's a range of performance. Think of it like chinese lumens
This is the description of the six cell pack I got from Torchy on ebay
Fluxient 6600mAh 7.4v battery with pouch compatible with Magicshine, Solar Storm
Paid £29.99 for it, not currently available but I assume it will be back on at some point.
Kaidomain are doing high-quality battery packs containing Panasonic NCR cells. My double even came with a nice nylon pouch which I didn't expect.

Where is the best UK place to get protected 18650 batteries from these days? Is it still torchy boy?
Just getting prepared for straffpuffa
Any links appreciated. Thanks
Don't know about best but torchy'll always be a good option
