ML-102 charger

http://www.intl-outdoor.com/ml102-usb-charger-for-18650-26650-battery-p-...

well the specs sounds good for me, but i cant find any review of it... curious`about termination...

according specs it could be fast charger 1A and maybe not very safe...

I have MP1 and like it, but this could be  used also as a power supply...

 

so does anybody have it?

I have to admit that when I saw this charger about 2 weeks ago I was tempted to buy, but....... I am also waiting for reviews, opinions, etc........

I'm not expert for those things like some people around here, so it would be nice if someone can comment this (cut-off, charging, discharging, etc..). Is this any good. Mini review of the charger is translated from Russian.

This charger got a very good review in the flashlight part of the german messerforum.net:

http://www.messerforum.net/showthread.php?107273-18650-Lader-billig-und-...

Here is a google translation: http://translate.google.com/translate?hl=en&sl=de&tl=en&u=http%3A%2F%2Fwww.messerforum.net%2Fshowthread.php%3F107273-18650-Lader-billig-und-sehr-gut-Miller-ML-Serie

I got some of those chargers and can highly recommend them. The build quality is excellent and it has a reliable termination at 4.2V. After the main LED turning green, leave the cell in the charger until the little LED in the housing turns green too. They really get fully charged this way.

Hiltihome states that overly long cells don't fit, but even my Xtar 18700 cells do fit.

Only 26650 cells don't fit very good. They fit in the charging bay but don't get good electrical contact. You have to work with small magnets.

I do recommend to use this charger with a reliable USB wall power supply or to get the version without USB input but with a wall adapter: http://www.cnqualitygoods.com/goods.php?id=1331

You're welcome!

 

Here is a little mod I did to one of my ML-102 chargers using this voltage display:

It can be used as a battery tester now and shows the actual cell voltage while charging.

How come according to specs could not be very safe? Smile

It has many LED status points. The output really cuts power when the battery is around 3V.
It's not 1A unless you have a power supply that can offer 1A, otherwise it's 500mA. Even a 1A power supply mayt not offer 1A since not AC to DC power supply is 100% efficient.
Very solid build, high quality soldering inside. When the LED is red then charging is really done. Also the reverse polarity protection is working.

About the termination. I have two, each of them always terminates at the same voltage, but not identical between them samples. One always 4.17V one 4.20V, I trust my multimeter on this one.

Didi you experienced that, 26650 cells not fitting well?

I have two chargers and they fit just well and charge just well, no issues. The cells I have are flat tops.

Yes. My KingKong flat top does fit inside the charger, but I have to use a small magnet to get realiable electrical contact at the positive side.

Could you give us some more details aout the display mod? Maybe we can do the same with some pictures or more information, how you connect die dispaly with the charger (my charger will arrive in 1-2 weeks).

I unfortunately did not take picture while doing the mod. But it's very easy:

I just drilled two little holes in the charger's housing and soldered a wire to the positive and negative solder point that holds the chargers battery connection springs. Then I connected the negative wire to the - pin and the positive wire to the 1S pin on the voltage display and hot glued the voltage display to the charger's housing.

Thank you. This sounds really easy. I will order a second and try it.

I just bought one of these displays as well. Let's see if I can hook it up to my Xtar MP1 Wink

What is the maximum voltage each of the 1-6s pins can handle ? Is it more than 4.5V ?

Thank you.

About the ML-102 charger:

I bought one King Kong INR 26650 raised top and (2) ML-102 chargers.  The raised top cells do not like to sit in the ML-102 charger very nicely.  The raised top of the battery slides up off the positive terminal of the charger (because the terminal just barely hits the edge of the raised part).  Seems the charger is really sized for 18650's. 

Anyone else using this combination?  Seems to me that for use with these raised top cells it would be best to file off some of the chargers rolled side (the way it's rolled to fit an 18650) to allow the 26650 to sit down lower. 

Here's a photo trying to show the issue:

1

It's tough to see the chargers positive terminal, but you can see how the cell is raised up off the "rolled edge" of the side of the charger.

King Kong Raised Top INR26650's:  Total length 68.05mm, diameter 26.33mm.  Battery is a tight fit in the ML-102 charger with just a mm or two to spare.

Charged up my King Kong INR26650 and terminated at 4.19v measured with a cheap DMM.  I then disconnected from the wall adaptor and plugged in my iPhone 3GS to see if it would start charging and it didn't at first.  I removed the battery from the charger and placed it back in and it finally started charging. 

Here's a photo showing my temporary solution to the raised top cell popping up out of the cradle (a rubber band):

1

I don't see any reason that I can't file down the rolled edges of the charger to better accommodate this raised top King Kong.  I can leave enough of the rolled edge to still firmly hold an 18650 (maybe file the edges down at the top and bottom to about the same level as the middle.

That sounds like a good plan. I dont see any reason it wouldnt work. And if you do like you wrote and leave the edge same height as the middle section it should remain structurally strong. 

This said without me having one of these. I never bought one because I could not find a review Embarassed

I was wondering if this charger will be able to fit the Xtar 18700 batteries. Also, does it come with an AC adapter or can I just plug it into my computer/cell phone charger? I am thinking about getting this over the Xtar MP1. Thanks.

Yep. It's a tight fit and needs some force, but they fit (at least 2600mAh ones, but I guess 2400mAh/3100mAh versions are same length).

Nope, no AC adapter - it only comes with USB power cord to plug it into PC/any other USB power source.

It's indeed better option than MP1, due to true CC/CV charging profile.

Just remember that it will only charge at 500mA from a computer connection but will charge at 1A from an electrical outlet (assuming your A/C to USB adaptor handles 1A+ output).  I bought some of these Apple type A/C to USB adaptors to use with it (not yet tested).

I've tested and it charges at 1A from my PC. Then again, my PC's motherboard has a feature called "3x USB power" so it might have something to do with it.

What is the full name of your MB? I've read that some USBs have been modified with charging purposes in mind. Could it possible do 1.5A max, as in 500mAx3?

It's GIGABYTE GA-Z68XP-UD4, and yes, it indeed seems to be capable of doing 1.5A max.

Most laptops and PC's with usb 2.0 will only give out up to 500 ma (0.5 amp). 0.5 amp is good for 18650's but no good for 26650 IMO then once you buy the added adaptor the cost is way to high for a charger that will not fit protected 26650's. But you could use a iphone 4 or a ipad power supply as they give out 1 to 2 amp.

But wouldn't you be better off with some thing like this for 26650,s at 1.5 amp

http://budgetlightforum.com/node/9437

or this one for 18650 or 26650 at one amp, it should fit protected trustfire 26650's at lest.

TrustFire Dual Channel Li-ion Battery Charger For 26650/25500/26700/18650/16340 - TR006 (US Plug)

Manafont have confirmed it is 1 amp per bay.

If you have a USB hub with an external power supply, you could use that. some of them are not limited at 500 mA.

Hey,

I ordered this charger (and lovin it) from Hank but forgot to get the spacers to charge 14500, anyone know a free shipping drop seller that sells appropriate spacers? I’m guessing these aren’t suitable, thanks!

If you buy something else of Hank (a product offers free shipping), you can write him an email or a PM to add the spacers and you will pay them with the rest of the order.

The magnets of Kaidomain will also work, but the size is 0,1cm. You need some more as ten for the charger.

Another option would be a thicker screw and you cut off the tip or you use some coins (I don’t know, if Australia has any copper coins?)

Light up the darkness.

Cheers mate,

Yeah we have copper coins here Smile probably too much work tho.
I was gonna order some stuff from Hank so will get him to drop those in aswell.

Thanks,

Has anyone tried the ML-102 with a high current phone like the Galaxy S 3? How well does it work with such phones?
