    Leonard- just told me that Panasonic batteries are not available to US, only if you buy a light. Also noted by Cat the square connectors do work perfect with MS and SS lights, I have last year BAT and Samsung batteries from Xeccon and still going strong.

    I also still feel Serfas bike lights are the best to can buy for the money, from the light head to the battery, switch, connectors all first class. Try to find a deal on one.

    Battery packs?
    I have some decent batteries that i would like to use in a 4 and 6 cell setup.

    Any recommendations on cases would be great. This appears to be the best one out there. A little pricey but looks solid.
    PANNOVO B-C04 Water Resistant 4 x 18650 Battery Pack Case for Bike Lamp - Black - Free Shipping - DealExtreme

    I've been unable to find a 6 cell case?

    also for the people out there making there own do you.
    A: Whats the best way to make sure batteries are paired? (i can source some good quality lenovo laptop batteries last set i got all 8 were great and have kept voltage without an issue)
    B: Protection circuits. do you buy the protection PCBs and if so any recommendations as i really don't know where to start on this.
    C: Leads and where to buy them from

    Just as reference I want to have a 6 cell so i can run two Yinding dual XML's from.

    Thanks in advance

    This is a very good case if you have your own cells. I have a couple for the lights I've made.

    Right now this case is sold out at DX.

    I don't think there is a 6 cell case holder yet.

    Just a quick question that is sure to be beating a dead horse, did a search, please dont sue me. Picked up a couple of lights from Amazon (assuming they may be "slightly" better than random ebay vendors). The brand is securtiying and they came with battery packs, how long do I need charge these? And how long is too long before it becomes dangerous? I already ordered a Panasonic pack for my head lamp which will be in my backpack and I will use the cheep batteries for the bar lamp with the pack mounted to the frame. Another question is I live in Switzerland (220v) but I bought these since Im in the U.S at the moment. I am assuming the charger should be able to convert 220v and I will check once I receive the package. I doubt the conversion should be a problem but I am worried about charging the cheap batteries. Any help or links to threads that have already covered this topic would be greatly appreciated. Thanks.

    Edit; one pack is 6400mAh and the other is 4800mAh

    Hi Swissam, a couple of options - (1) use the chargers that come with the lights or (2) buy use the buy a hobby charger - eg see this thread & this website.

    Check when you get your hands on the charger, but AFAIK all chargers use switchmode power supplies and should be compatible with 110-240 V, you just need an adaptor to use the correct plug. You should not have to remember which charger belongs to which battery as either charger should charge either battery.

    Personally I prefer to use a hobby charger but the vast majority of people just use the charger that comes with the light.

    Thanks for the tip. Just wondering if these chargers have an automatic shut off once fully charged. Ill wait until tomorrow as I dont want to leave it on all night. How long do these battery packs normally take to charge up?

    Getting a 2 cell 18650 light set up via slow boat (MS 816 clone ) that use individual cells in a cradle , my question is that when I upgrade cells do I have to have Protected cells ?

    Is there a battery case that i can fill with 2x18650 cells? For my Yinding light I use at the moment the Pannovo 4x18650 battery pack with some Panasonic cells. As my nightrides are normally very short (about an hour or so) I want a lighter, less bulkier battery case that I can fill with only two 18650 cells.

    I am looking for a case similar to this case on the left from Fenix:

    All chargers for Li-ion batteries are designed to shut off once the full charge has been reached. Most batteries are shipped with a 40% charge. Should take about 3-3.5 hrs. for the initial charge. When fully depleted the battery might take 5-6hrs to recharge. I highly recommend charging in a safe place and under supervision. Anyway most chargers have an LED indicator that will change from red to green when the battery is charged. Once charged it is a good idea to remove the battery and charger from the wall power outlet. I say this but only because i know that sometimes a voltage surge in line voltage can damage cheap electronics.

    @ C.M.S. > About the protected cells; Not a big issue if you know when to switch out batteries.

    @ randan > Don't know if there's a cheap 2-cell ( series ) holder but at least you have the one sold by Fenix that should work as long as the plugs are compatible. Option two is to just buy a two-cell ( 2-series ) battery. I bought one from Hunk Lee ( ebay vendor ) using Panasonic batteries for a good price although if you choose this option you will need to weather proof the battery ( which is not too hard to do ) The Hunk Lee connectors ( though not the best ) work fine depending on what type of connectors you have.

    I'm sure you can use the Pano's with two cells. It won't be less bulky, but will be lighter.

    Patski, I have one of the Xeccon Ulitmate 6800mAh batteries. It is definitely the best packaged battery you can get for the price. Unfortunately living in the USA you might not be able to obtain one at the moment as the last I heard they ( Xeccon ) weren't selling these ( aftermarket ) to the USA due to shortage of stock ( inside the USA ).
    If you want one you might have to contact Leonard from Xeccon and check on availability.

    Your right, thanks. Took about 3hrs to charge on 220, the charger was warm but never got too hot nor did it explode and burn my house down. I did however order two Panasonic packs from hunk_lee on ebay but I will keep the cheapo chargers as they look identical to the ones on hunk_lee's page. I tested the lights out on a friends farm in the middle of nowhere and these lights (ones I listed above) light up the whole field and will be more than enough for trial riding. I'm hoping I won't run into too many problems once I get the upgraded battery packs as these lights seem to be well built. I spent a little over $100 for both set ups (including upgrading the battery packs) and so far I'm more than happy with them. Now I just need to mount them and go ride....one the rain stops.

    @Wombat...Having used the Xeccon batteries with the squarish connector plug myself I think some clarification is necessary. The metal connector on the Xeccon battery is actually round, just like with any other Mshine type battery. What's squarish on the plug is the rubber shield. Strange as this might seem, it works perfectly well with any lamp I own that calls for a Mshine type batttery. ( * The exceptions are: DiNotte...which doesn't work with any Mshine type battery without modding save the Hunk Lee's ) And, The Mshine type batteries that use the "screw on" connectors.

    Truthfully, I don't know if any of the standard Mshine type batteries I use have connectors that are fully waterproof. Almost all the ones I own, ( except the Hunk Lee ) are very well shielded though. The square "Xeccon" ( female ) plugs work so well with my standard ( round/male ) lamp plugs that I really don't see there being a real issue ( or need for an adapter ). The fit is very tight and looks very"weather-resistant" to me if not completely "water-proof. I will also say this about the new Xeccon ( squarish) plugs; Used in combo with the matching Xeccon lamps... The fit is so smooth and tight I would bet money that they are water-proof to 1 meter.
    Maybe I had too many post ride beverages last night, but I can't envision how the fit between the "square connector" on the battery pack can have a tight fit with a MS type "Round" connector.

    Is anyone able to post a picture of this connection. I would like to purchase one of the Xeccon Samsung Battery packs as a replacement pack for my MS, Gemini, and SolarStorm lights.

    I PM'd Leonard, these are currently NOT avail in the US, he's looking into it, will ping me when/if a decision is made. Hopefully he'll post to the community...

    I'll try to get some photos during the weekend. Xeccon also has the adapters
    ( square to round ) FWIW. If you needed an adapter I wouldn't think that they would cost more than a couple bucks but like I said before works fine without it.

    The Xeccon 5200mAh battery should work very well with any lamp using 1-2 emitters. For years I ran my Gloworm X2 using 3yr old Bikeray 5200mAh batteries ( BAK cells ) and never had a problem. The Xeccon's with Samsung should be even better and as a side note the Samsung 2600 cells should be lighter than the Batteries built with the heavier Panasonic cells. Not that it is that much difference but I can feel the weight difference ( in my hands ) when holding the Panasonic 4-cell built with 3400mAh cells.

    If you're looking to order batteries from China, word is that most vendors (DX, Fasttech, Walbuys, etc) are having issues shipping them out. Especially to North America. Shipping companies have deemed these batteries as hazardous and highly explosive. It'll be hit and miss when ordering from them.

    Your best bet is to order within North America, price is higher, but at least you'll receive your order.

    Where are all these vendors like fasttech , DX , and others that sell individual high quality panasonic cells in particular for a very discounted price based out of ? And are they authentic ?

    China...as far we know they are authentic. They buy in bulk so can sell for less.

    This pack came with an SSx2. I'm having a hard time understanding what configuration this is? Seller description is 8.4V 6400mAh. On the sides of the batteries it states "IRC18650 3.7V", only other marking are the + and - symbols. I can find the IRC models in 1600, 2200 and 2400mAh. Samsung makes a pink IRC18650 model in 2600mAh. These must be the Purple People Melters.

    Someone effed up building that battery. It should be a 2S2P configuration. The mAh rating advertised as 6400 is using Chinese mAh which really equates to about 2000-4400mAh in reality.

    As in 'its not configured properly'? Because the configuration does not look like anything I've read about yet.

    Edit: I had the battery charging for four hours today, after testing today. The light on the supplied charger is green, so I guess that means the charger thinks it is full. I set the multimeter to DCV200 and the battery reads 8.4V on the MS power plug. My multimeter is nothing special($12 harbor freight), its amperes setting is 1.5V 4A, and gives a reading of 23.8.

    [SSx2]If I were to balance the Trustfires I linked and build a 2S/2P pack, what PCM would I want to buy; through huck_lee or or will this one work

    This is the middle wire of the 2S 3 wire setup on the photo. You can clearly see that one cell of three should be reversed. There should be two positive and 2 negative cell terminals if you want a proper 2S2P setup. The wiring here is wrong!

    The setup looks very wrong from everything I've read over the last week, what I want to establish is if this is even a type of battery configuration? We know it's not 2S2P, so what is it, just bad assembly?

    With a 2S2P configuration, I think I need a PCM that will handle 7.4V with 8A Maximal continuous Discharging current? Will this PCM work for x4 18650 protected 3.7V, 2300mAh Trustfires in 2S2P configuration, to run the SSx2?

    It is a 2S1P and the rest 2 cells are useless in that config, IMHO

    Okay, pulling it open again to see what PCM was used, since I didn't flip it and get a pic last time. Though, I'm going to drain it again before I do.

    Edit: 58f and raining out. Placed light behind house out of the rain with a sheetmetal bucket to capture the light, light is set on high. Put battery to MM before test, DCV reads 8.4v; (1.5v/4.0mA) setting reads 23.8... I need my friend to get back in town so I can use his analyzer... I got phone recording time to cut off. Will report how long it last.

    I see, it should be like this, yes?

    Almost One red wire on this picture should get two plus cell faces and the other two minus faces. The biggest problem here is that three cells are plus oriented and one minus. Two/two would be OK. You need to split this pack or rearrange one cell - the topmost cell should be enough.

    Being that i missed out on the Waterproof case (thanks C.M.S) i kind of thoughts i don't need it. The 2 cheap 4 packs i have to date have survive just wrapped in sandwich bags.

    My new thoughst are just use
    2 of these
    A Battery Holder/Case for Li-ion 18650 17670 battery 2S1P w/PCM output:6-8.4V | eBay

    or create a pack using these:
    5 Pcs Black Plastic 1 x 3.7V 18650 Batteries 2 Pin Battery Holder Case | eBay
    i'm just confused over protection circuits. do i need them? Being that i plan to use and charge batteries in my nightcore charger

    I bought 2 of those so called Panasonic's 3400mah (via China) and the run time on my Ultrafire XML U2 is about 30-40 min before light output starts to diminish. So I would say they are fake.

    Guess I'll just pay the freight and get the real ones but where do U buy so that U know they are real.

    Okay. Battery stripped 'again'...



    Flipped one battery for a proper 2S2P configuration. So then I decide that I need to test every cell. Okay, so two of the cells did not show a charge on DCV200, switch to DCV20 to look for really low voltage... None! Either the two batteries that were not wired correctly have deceased, or they have never been charged. At full the battery pack is 8.4V, 2380mAh. At cutoff the battery pack is 2.83V, 1170mAh.

    So I try to see if the i4 will tell me anything. I stick one battery in and in about 60s it tells me the battery is fully charged. When I remove the battery from the charger and test it, it shows (DCV200)1.6V. The charge wont climb any higher and the charger says it's done charging in less than one minute. Okay, so lets try the other battery in the i4 and see what I get. After 60 seconds of being in the charger, the charger is not reading that there is a battery in the charge port, the light does not even blink as it does when reading batteries, so I figure that the cell that was pointed out as needing flipped by you guys, is a dead cell, and all it has been doing is restricting current since it is the battery connected to the positive terminal with all the other batteries behind it.

    So I'm going to set aside the two working pink 18650's for now(which actually have a tight rating to each other; well matched) and wire my Trustfire 2300mAh(rated 2500mAh) batteries in 2S2P. Though, I need to find those "U" shaped ribbons, or any battery building ribbons(don't really know the name) like the ones a few pages back, because I've called all the battery and hobby stores in town and no-one sells the supplies for building batteries, except for shrink. Though there are plenty of shops that will build you one 30% more than online cost.

    Checking the number on the PCM, it is in fact a 8A protective circuit.

    I took all my trustfires and charged them one-by-one. Between all four Trustfires(using friends analyzer) there is no more than a .16V difference between the lowest charge and the highest charge at full battery, and there is no more than a 68mA difference in two of the cells. Seems safe?

    So my biggest issue right now is locating a place, either on the net, or within 25 miles of me, where I can buy ribbons for making battery packs. Links and answers are greatly appreciated!

    Vancbiker, if you have any of the ribbon in your stock, I would gladly trade you some beer and/or money for 5" in ribbon?

    Sorry, don't have any of that. I either buy pre-made packs online or use battery holders. Those factory connections are spot-welded with a special machine. There have been a few posts from folks that were able to get that done at local batteries plus type shops. There have also been posts where folks have soldered the connections to the cells. Unless you are quite proficient at soldering electrical connections, I would not advise doing that. It would be easy to kill a cell by overheating it during the soldering.

    Forgot to add...

    If you need to re-configure a pack in the future, do not pull the spot welded tabs off the cells. Cut them apart leaving a half inch or so of the tab attached to the cell. Then you can easily solder new connections to the remaining tab without risk of heat damage to the cell.

    After looking at this photo and knowing what lamp the battery was sold with, I feel at this point I would have to tear the shrink wrap off of every cheap Chinese battery I own just to make sure I don't have one of those. It is very obvious from the photo that only one cell is on the positive side when there should be two ( assuming two cells in parallel connected in series ( positive to negative ) to the other two parallel cells ). This scares the crap out of me. Someone must of left their glasses home that day before getting to the assembly line.

    @pdxmark, If I were you I would contact the vendor to get a new battery...AND, if you got this from an e-smay vendor I would lodge a complaint with e-smay.

    ( Edit; I just removed the shrink wrap off of one of my cheap batteries. No problems with mine. Actually the connections look much better than the one that pdxmark has. Anyway, still a good idea to check it if you own and actually use one of these. Personally, I only use the cheap batteries for testing and that very rarely.

    Are you just going to get a large 2" wrap like this? Will 2" fit?
    10' Black Polyvinylchloride Heat Shrink Tubing

    Will clear work? That could be interesting.

    Somewhere on one of these forums, I saw a battery pack photo with a hollow tube in place of one of the cells...

    Truthfully, I've never used heat shrink tubing that large before and I don't own a heat gun. I just know if you use it that it will have to be big enough to get the battery inside "before" you shrink it.

    If I were going to use this battery outside I would likely just replace the shrink wrap with black duct tape which sheds water very well. Then if I wanted it to be completely bullet-proof I might use the "Plastic dip" product or try a can of "Flex Seal" and apply that over the tape. I've never used PD or FS before so I have no idea if they are worth the money. Many people on this forum have used Plastic dip, never heard if anyone has ever tried what I suggest.
