    Zuuds,
    A year ago I bought a 3x XML light that came with a battery that only lasted about 1.5 hours ( my rides tend to be over 2 hours)
    I dropped around $30 on a Kaidomain battery that came wiht no pack or charger...and only ran about 2 hours.( and run time got shorter after each charge)
    I ended up with a Xeccon hardcase from Leonard/ mtbrevolution that runs over 3 hours...and still going strong.
    If I was going to do it over...I would try to find the light head seperate and buy a good battery.

    You've done your homework. The cells you listed are reliable. While Panasonic will give you longer runtime to weight ratio, the another important question is how long are your average rides. If you say about 3 hours then the Gemini Samsung 5200 will do the job. We have similar batteries with neoprene pouches heading to CO next week.

    If you want to trade a sure thing with cheaper higher capacity Panasonic packs with no waterproofing protection or pouch, unknown shipping time and impossible to return warranty should it go south then its your choice. I will most defintely take Archie's word Hunk Lee is legit but can anyone say he's test each battery he gets from his suppliers, or his supplier's suppliers.

    Cool, the more options the better! As you point out, a lot more unknowns (and less goodies) with the Hunk Lee packs, but they're about $20 cheaper than the Gemini packs, so depending on one's risk tolerance, it could be worth the gamble. But if you can pick up a brand name pack on sale and there's only a $5-10 price difference, then it's a no-brainer to go with the brand name pack.

    Very surprised and appreciate that so many people talk about my products!
    The two connectors infact from same position marked P+~P-. Someone want to charge the battery when they use the battery at same time. Keep one if you only need DC socket. The finally product has PVC tube to protect inside parts.

    If anybody want this battery pack - here is your chance to get it, paypal payment available too.
    Be warned though that it doesn't have any protection pcb in it, I just received my pack from aliexpress. Basically its a direct clone of Fenix BT20's pack, just for 4 cells. There is no low-voltage cutoff or any cells monitoring so you have to use protected cells or rely on your light's battery indicator.

    If you guys are looking for a good quality battery pack. There is a sale going on right now at Banggood for some Panasonics 18650's. Deal can be found here from the BL forums.

    You combine the batteries with this holder and you have a 6800mah water proof pack for about $45.

    Do you know if the Panasonic NCR 18650B Protected (length 69.6 mm) fits in the PANNOVO B-C04 holder?

    If you go back a few post, I think Kir confirmed that the protected NCR's do fit. I don't have this case, but I do have the similar one from the BT20 and protected cells fit.

    I like this case and may pick up a couple.

    Wow, nice find, thanks.
    Anyone knows if they would fit into this box: http://kaidomain.com/product/details.S021564
    Since box has protection circuit I need unprotected batteries, right?

    FYI...This is a good price if you need the batteries now. If you can wait, the price for these cells has gone as low as $12.30/pair (flat top unprotected) during one of their Wallbuys group buy.

    Hmm, my holder (like this one) is not working anymore after I've opened it...
    I've checked all 4 cells, they are fine, but there is no electricity from whole pack. I've checked all wires and all element, everything looks ok. Any suggestions what could be wrong?

    Don't know. You'll have to keep your eye on the BLF deal thread.

    Its a tight fit and you may not be able to fully close the top cover but they will work.

    1) Observe the polarity markings on pcb when inserting the cells, this is very important!
    2) After opening/closing the pack you have to reset protection pcb by connecting it to the charger.

    Kir, thank you very much.
    Connecting it to charger did it . I was connecting it to charger to see if light on charger turns on - if battery pack is working, but didn't try to put charger into power socket.
    After connecting it to power socket it is working again.

    The final battery will be heat shrinked by PVC tube to protect it from short circuit. Just show connect material. Don't use the battery with poor connect material and mode, as it maybe short circuit and with poor electronic performance.

    Questions:

    Do people here making battery packs use protected cells or add protection circuits? If the later any recommended circuits

    Has anyone found a good twin/2x 18650 waterproof battery holder?

    Lastly can anyone recomend a good source of cheap mj extension/y cables for making battery packs.

    Thanks

    The latter, of course. Browse eBay: normally there's plenty of them; just read the descriptions...

    The cheapest source I know of, is DealExtreme.

    We made battery pack with PCM inside. The PCM can protect Li-ion battery from over-discharging, over-charging, short-circuit etc. Like below linked items:
    items in A-OK battery store on eBay!

    For the battery holder, like this:

    Just received my 4 cell Panasonic 6200mah from HunkLee. Took about 10 days to arrive on the west coast. Arrived very well packaged and appears to be a high grade quality pack. I will be conducting some run times this weekend using my gemini light heads.

    Hi HunkLee, Welcome to MTBR "Lights and Night riding forum". I see that you're a vendor of batteries. Nice prices on your website. I hope you have permission from MTBR to post and list your website on the forum. The vendors who post on MTBR have to pay a fee to carry ads or to post links. Approved vendors get to post on the forums as well. If you haven't contacted one of the moderators to attain "Approved vendor status" you may want to do that so they don't remove your posts. If you are already an approved vendor for MTBR than by all means WELCOME.

    Good to know we can actually get the batteries from him.

    I purchased 2 3100 Panasonic cells from Fasttech and a 6 cell from DX and have been waiting. The Fasttech people said the batteries are on hold in China and might not be able to be shipped and would refund me if not.

    I really just needed the batteries. It's been over 3 weeks.

    I read others have had this issue. Do you eventually get the batteries.

    Thx

    I also ordered some batteries from Fasttech and have been waiting. Current tracking indicates:

    "The item (trackingnumber) was posted on 6-Nov-2013"

    mb, do you have tracking info, if so, what is the status of yours?

    I haven't contacted Fasttech yet, I placed my order on Oct. 23 (2 days over 3 weeks).

    edit, perhaps I shouldn't have included my tracking number, removed.

    If you're buying loose cells, Amazon's probably a better bet. A few bucks more, but you avoid the infuriating delays.

    My status just says in transit but I sent an email to F/T and they explained the issue. I've been waiting since 10/20.

    I'll wait a bit longer and if same issue.

    Based on F/T response to my email, it's as though they know these orders can't be filled but they are just trying anyway to see which will go thru.

    F/T response to me. "Since your package contains batteries, which are not allowed by Hong Kong Post due to aviation security reason, we believe your package is now waiting for inspection. Therefore, we will found the tracking status remains "acceptance". If your package is caught and returned to us, we will arrange refund for you."

    This battery will come heat shrinked? Or are you talking about a different unit?

    Did two run times on high using a gemini duo at work. Temperature 44-35 degrees. First run time was 3:29 second was 3:27. Very impressed with this 4 cell Panasonic 6200 mah.

    Great battery HunkLee.

    Looks like a good set-up.

    @HunkLee....Someone also mentioned wanting a 4-cell 2S2P set-up using Panasonic 3400mAh cells. I'll second that request. There is also a market for a 2-cell ( 3400mAh ) two series pack that so far not too many vendors seem to sell. A number of people here like to run two cell packs on their helmet or run two cell packs for smaller rear lamps. Make them and they should sell, particularly since there seems to be some problems with getting batteries from the other side of the world at the moment.

    Yeah, they simply can't send batteries from China. I'm assuming loose cells only but not really sure as I have a 6 cell on order. Hopefully that will actually arrive. Might be day light savings time again by the time it does arrive tho. Haha.

    Here's Fasttech response.

    As you may have noticed that there was no tracking updates for your package during the past few weeks. After confirming with HongKong Post, we've confirmed that your package was failed to pass through the x-ray check and has been returned. This was caused due to current strict inspection of the aviation security.

    Your package has just been returned to us. Considering the risk of being returned/delayed again, we are going to make a refund for your order. Because there is too many orders being affected, the refund will be done within 24 hours. Your understanding would be highly appreciated.

    What's the typical expected lifetime of a good 4x18650 pack? I purchased a couple of the Gemini 5200mah packs last year. I've been using them on average 3 times a week, for 1.5-2.5 hours per ride. I recharge after every ride. The batteries are kept in a climate controlled area. I'd guess I've got 200 charge cycles in them so far.

    I've noticed recently that my battery indicator on my lights are now getting into the 'warning' range 1.5 hours or so into a ride. I definitely feel I've got my $'s worth as they've been flawless and still last 2+ hours on high on my MJ872 clones. I want to replace them as the warning lights make me nervous on longer rides.

    Is this life range typical? Better than average, worse than average?

    Hmmm, well I still need the batteries and on their website it says:

    "US orders are now routed via the same service provided by Singapore instead of Hong Kong Post.
    Delivery times will be more consistent across the board."

    So, I'm hoping they resend the order. Guess I'll see what happens! Which will come first, Christmas or batteries!

    hey, just want to mention that your plug is not compatible in terms of waterproofness for most bike lights guys are using here!
    Maybe you should consider to use a magicshine style plug!
    Or would that be an option as a special request when ordering?
    ..just ride...
