A $15 imax B6 will charge at up to 5A and works great, although the cell holder to go with it costs another $3 or so. Still less then $20 for a charger capable of charging them at 1.25A each if budget is the goal.

Otherwise I am not aware of any pre-made chargers that would work for cheap.

Have you got a link to that T_A? Thanks in advance. Smile
This one is a bit more then I spent but I am sure you can look around and find one a bit cheaper if you wanted:

http://www.ebay.com/itm/252047704675?_trksid=p2055119.m1438.l2649&ssPage...

Takes a bit more know how then just jamming the cell into the slot but it is cheap and very effective. If you flash new firmware it gets even better.

Thank you for the link T_A…….. Thumbs Up

Hmmm, I have almost all protected cells. Any pointer welcome to a slightly longer cell holder wired parallel.

I have the HobbyKing clone Accucel 6
but I’ve only used it for charging one cell at a time, so far
(e.g. it works fine for the 3.6v NiMH Black and Decker Versapack cylindrical cells)

but I ought to get into multiple-18650 lights at some point, without blowing anything up.

You can get a 26650 holder for protected 18650’s most likely. Mine are a bit longer and should fit a protected cell, I don’t own any protected cells to try though.

Mt friend used to run the Maxamps 1 cell lipos in a range of things, coupled together as what ever he needed to power, but he always charged a bunch of those as 1 cell and then put 20 amps on it.
Still took a while as this was 5450 mah cells.

We lovingly nicknamed the batteries “The LEGO batteries”

If you want to charge a lot of batteries and do it fast.

I will probably go that route as i have a few RC chargers too, and they might as well get som exercise charging round cells too beside the square RC batteries.

I think I remember far back in this thread, someone asking about thread locker for the tripod thread, hence this post. I just remembered that post and recently discovered this product for another use.

If something like loctite is used it can be undone with heat and tools no matter what grade is used. But another product is available that won’t harden and is reusable and adjustable. Those are good qualities where one needs increased friction to allow potential removal of the 1/4-20 adapter in the light but not so much friction between the 1/4-20 adapter and the tripod plate. I have a similar issue with firearms and threads that require increased friction but where I don’t want to use hardening Loctite. Vibra-tite VC-3 is such a product. It’s a polymer that requires 30 minutes to dry before the threaded part is reinstalled and once installed it can be removed and reused (3x). Once applied there is no time limit before it can be installed into the thread. I suggest just applying it to one side of the thread to see how that works and only use one application. Don’t ask me how I know this Smile .

I would have posted sooner but just recently discovered it. It’s available in many sizes.

As I write I have the 1/4-20 adapter for the MK41 drying before reinstalling it into the light. It should work there. It definitely works in the more critical firearms I’ve used it on.

> vibra-tite
Be careful with that stuff, it uses MEK (Methyl ethyl ketone) as a solvent.
That’s in the “know when not to inhale” category.
And don’t get it on your skin.

I’m thinking the Panze can only do 2 26650 and 2 18650 judging by the narrow inner slots.

I think I need to look at the opus. It physically looks like it will hold 4 × 26650. Thanks.

I just tried the Opus. It won’t fit 4×26650

Right the Panzer only has space for 26mm diameter cells in the 2 outer slots. If the need for 4 × 26650 was mentioned I missed that. Sorry.

Yes it does, but IMO it’s a very low concentration. They have other versions that use other solvents, VC-4, VC-5, etc’. At least that’s what I got out of what I read. The amount used is also very small. Surely less than a drop per adapter; the amount of MEK is very tiny in that drop.

Thanks for the warning though. I have a history with MEK and respiratory problems. Many decades ago I used it literally by the gallon to clean extruders that ran at 300+°F – 400°. We’d pour it in one end and it would come out the other end. The MEK fumes were like a fog. As I wrote, I had respiratory problems from it. VC-3 is nothing at all like that. I couldn’t even smell it when the bottle was open.

If you have to charge 4 × 26650’s at a time…. Just get two of these Bad Boys and do 4 at a time at 2A each. Wink

Excdllent charger BTW. Smile

Maybe a group buy? Buy 50 or more and the price goes down to $17.

I’d get another at that price. Thumbs Up
I got mine on a Black Friday sale for $20. Very pleased with it too. Smile

For parallel cell configs like the Q8, it’s probably a good idea to use a single charger for all four cells in order to get the cells balanced. Different chargers have different termination voltages, and when you put the separately-charged cells into the Q8 they’ll immediately cross-charge each other to equalize any differences.

Even reasonably good chargers still have a margin of error, with some units stopping at 4.17V and others stopping at 4.24V. That’s usually fine for a single cell, but with four cells in parallel they really should match each other as closely as possible.

AI is fun, no? For simple text generation like that, a neural network is probably overkill… it’s easier to do that sort of thing with Markov chains. Things get really fun with more detailed simulations though, like tools to convert from line-drawings to photographic images. Here’s a fun online version to play with:

For example, I used my Mad Artsy Skillzz ™ to make a shoe… and a purse… and a hipster sasquatch.

Excellent advice…. I totally agree to. That is what I do/will do for the Q8 also.

My bad also…. I thought he was asking about 26650’s.

You’re right; I think he was indeed. But for anyone looking for a Q8 charger, be aware that doubling up for faster charges may not be the best idea.

A quad 26650 flashlight in the Q8 flavor would only be good for one thing, and that’s for assuring someone will sleep with the fish for a longtime Big Smile

I thought about this one, but getting 2 of them with 2 cords plus the VC4 I already have is pretty messy. Cords will be everywhere! Lol.

2 of them probably is my best bet.I could charge
4 × 26650 at 2A plus
2 × 26350 and 1 or 2 Misc 18650 at 0.5A all at once!
Then when they are done I can do
4 × 18650 at 1A.
Same brand, same simple interface. Yeah, seems like the best choice. Thanks.

Given that I usually get at least a month out of a single 16340 cell, or several months from 1×18650, I probably won’t need to charge the Q8 more often than once per year. I really don’t mind charging the cells in a cheap Nitecore i4, even if it takes 8 hours, since it happens so rarely.

I suppose if you use it all night every night though, like a security guard, charging speed might be a lot more important.

Yep, I do night security work. Lots of lights, lots of cells, but luckily I can charge them all at once, just once a week.

BTW, the SV2 is practically half price at illumn. I’m not sure if they are a sponsor here so I won’t post a link, but I’m sure most folks can find it just fine.

Got me 2 on the way!

I use the XTAR Rocket for my 26650’s, at 2A charge rate. Would’ve sworn the question was about charging the 4 18650’s of the Q8 all at once at 1A…

One could always buy 4 Utorch UT02’s and charge the cells at a 3A rate in the lights… Wink
