SheKor Charger for 18650/17670/18500/17500/14500/16340/

[Dances with Flashlight]

Is that normal for where you live? Or don't have enough experience to say?

Have no experience with this company, but would note that AW seldom takes more than a week to get batteries here from HK.

KD is slow but after 5 weeks of no delivery, I would certainly send them an email advising them that the product has not been received. Perhaps they would ship a replacement. Couldn't hurt to ask.

I thought this thread could use a photo of the SheKor in action. Note how the LED for the bay with the blue 14500 has gone out indicating fully charged (and no trickle current being applied), while the 18650 is still charging. I've found that when only charging one cell, it's a good practice to keep a fully charged cell in the other bay rather than leave it empty otherwise the LED in the empty bay will continue to blink which I think indicates that the charger is continuing to power that empty bay probably checking for status. But with a charged cell in there, it almost immediately just turns off.

(The stock power adapter that comes with the SheKor is shown in this photo although the unit is being powered by another adapter that is not shown in this picture.)

I don't think it's possible for the charger to give power to an empty bay. There is no electrical connection, so there's no power.

According to my SheKor box, it says: "Saving Warning: If no battery condition, LED light circularly flash .5-2 seconds, please take off the power dapter[sic] for power saving".

I have no idea what that means hahaha

[pae77]

I take it to mean that power is being wasted on the empty bay by the chargers continually checking for and finding the "no battery condition." That's why I think when charging only one battery at a time (i.e., using only one bay), it's better for the empty bay to be effectively shut off by having a full battery in there. Jmo.

Still waiting after five weeks.

I ordered mine from e-lectronics.net. I think it shipped from the Pacific Northwest.

Likewise. Fast, reliable shipping. Nice to order from within the states as well.

I also ordered mine from e-lectronics in mid April. I got 4 AW protected RCR123's at the same time that have been charged 3 times each for a total of 12 batteries being charged. They have ranged from 4.12 - 4.16V with an average voltage of 4.14 volts.

It appears they either come off at 4.12 volts or 4.15/4.16 volts. I haven't paid attention to what bay they are coming out of, but one bay may be charging slightly higher than the other. IIRC, my second charging of all 4, I restarted the cycle several times after completion and got 2@ 4.15 and the other 2@ 4.16 volts.

I got this charger instead of the WF-139 after some of the initial good press I read in this very thread.

All in all, I am more than happy to sacrifice small amount of run time in favor of less chance of fire and less stress on my batteries.

guys, I recieved mine today....

Noticed that the power unit says an output of 12V, 500mA.

Am i correct that the chrager can be pluged in a car 12V socket with the proper wire/jack used?

thanks...

[kosPap]

sort off found the answer to my question today.....

pluged a wall power supply I do not recall if it outputs 350 or 300mA at 12V.

My reservations are on powering teh charger with a cable straight from the car 12V jack....will its electronics determine current drawn from teh abtt, or will ti max out and POOF?

I also measured the SHekkor power supply....13.95V and 150mA with one batt at the charger.

Boy that charger requires patience! from 4.1V on current fed to the batt was 70mA ONLY....just before finishing I took a reading, and the charger was pushing 30mA!


Did not had the chance to measure termination volateg cos I had the DMM rigged on the batt in A mode...

[Quension]

The electronics determine how much current is drawn from the power supply, so you don't have to worry about that.

What I'd be more concerned about is the fact that car power tends to be very dirty -- it's not a flat 12V, and can be noisy. If the input electronics aren't set up to deal with that, it'll cause problems. It might power ok, but get confused in the middle of a charge cycle, or something equally strange.

It should be safe to run with the car off, nothing else running (don't turn the heater/AC on, etc). I'd wait for comments from others before trying with the car running.

[kosPap]

thanks quension....I sort of expected all thsi but I needed a confirmation...

I just ordered this charger from e-lectronics. Fast shipping from the US of A. This charger(and favorable cpf reviews) is the reason I decided to make the plunge into li ion. Well I was eyeing the pila. And still am. I haven't tested it out yet as I've only just ordered my first aw cells. I just want to go on record as saying that the availability of safer charging options has sold a few more lights in this camp. Frankly li ion gets a healthy bit of concern from me, even though I plug in my phone and toss it in drawer every day.

[pae77]

A healthy bit of concern is a good thing. Just check that it terminates below 4.20 and shuts off the way it's supposed to when finished charging. If your sample works as it should, I think you will probably like and become quite comfortable with it.

I thought the idea of CC/CV was that first the charger pushes a fixed current until the cell reaches a certain voltage, then it applies a fixed voltage at an ever decreasing current until it reaches zero (or very close to it). If so, at 4.1 volts, shouldn't the current be very low?

EDIT: I just went back in this thread, and saw that it does not adhere 100% to the ideal CC/CV charging algorithm, but, that it is close. And, at the end of the charge, it is supposed to decline in current output to a negligible amount...right?

If you look a bit further in, you'll see it mentioned a big problem with the charger is the spring resistance. In my case I reduced charging time by about an hour IIRC by semi fixing the problem. I still didn't get a proper CC/CV although the current doesn't go as low so fast. I'm planning to do a writeup, but wasn't happy with how my mod went so want to try it again but haven't got around to it.

[LEDAdd1ct]

Thank you. I will look again.

When you get around to it, if possible, I would like to see some photos showing the precise solder points, (although my motivation for doing this mod has diminished since I got an inexpensive hobby charger that does employ a true CC/CV algorithm (and provides real time display of charging currents and voltage while it's at it). But I still want to lower spring resistance as I may eventually mod one of my Shekors to act as a dumb cradle for the hobby charger.

there is a cinese thread with shekkor tests....the graphs there are indicative of the chraging.....level current pushed and then slowly declining from 4.1 on....

got to dig up the link...

[LEDAdd1ct]

I'd love to see it when you find it.

Do you refer to the Japanese site I mentioned (with link) in post 72 of this thread?

After my Shekor charger failed to arrive, KD kindly mailed another which I received about eight days after mailing.

As others have reported, it appears nicely constructed, is simple to operate (although the printed info on the box is not quite as informative or understandable as it could be), and seems to work well without any problems at all. It looks like this is going to be a good performer and a very good value.

Keeping an eye out for the mod to decrease resistance.

[Monocrom]

Looks like a nice, decent, budget charger.

yes that was the one...

Has anybody tried the new Redilast 18650's in this charger? Will they fit?

[OCD]

I can't speak for the Redilast, but I have a xxxfire that measures about 65.2mm that fits easily. Pulling the battery back as far as the charger will allow yields about 2mm of clearance between the battery and charger terminal. I would dare to say MY charger would handle a 67mm long cell. YMMV.

[Teobaldo]

This charger works fine with the AC adapter and with mi Brunton Solaris 6 solar panel (5 hours of solar charge for my 18650 battery give me 1 hour of Turbo Mode in my Fenix TA21). It's the charger that needed for the house and to leave camping. Thanks to old4570 for the thread, perhaps buy another to have it as replacement (the price is very good too).

This is post 15 from the above referenced thread for the Redilast cell sizes:

Cell sizes:


2200: I'll measure it later.
2600: 68.35-68.40mm x 18.2mm
2900: 68.85-68.95mm x 18.5mm

Hmm...

hmm do I understand correctly that you just hooked the charger at the slar panel? what does your panel output?
any pecularities?

that is very worthwhile find! thanks...though you made me want buy an one more!
