Thread: 26650 Batteries for the Big Bruiser?

    If you use the Lighthound 26500 you will be 1.5cm short. You will need to use a spacer. Due to the design of the BB this maybe not ideal as there may be a rattle when the switch is twisted out for momentary or off position.

So now I have this awsome "LOOKING" flashlight and cannot buy a battery to power it! Any suggestions?
    Can't say I didn't warn you. You could try some of the "INR" 26650's. I have no idea how those do, but the IMR 4000mAh cells are not being made anymore.

    Does Wayne have a specific recommendation since he built the light?

    The linked cells look to be the replacement for the discontinued 4000 AH, which were fantastic cells.

    alpg88, thanks for the link and they must be new as I called batteryspace over a week ago and they made no mention of these and they were not on their web site! I ordered 2 and I also ordered 2 king kong 26650 batteries, so hopefully one of these 2 manufactureers batteries will work in the Big Bruiser. BVH, the batteries that Wayne originally recommended are no longer being manufactured and I think that company may have gone out of business.

    They were bought out by a solar company, and stopped making the 4000mAh cells. 3500mAh are still made by that company, but the price went up considerably.

    I had purchased 2 Keygos 26650 batteries and after the first one did not power the Big Bruiser properly I never tried the second one. Well tonight I tried the second one and much to my surprise the Big Bruiser now not only looks good but throws one heck of a lot of light! Don't know why one works and the other one does not, they both show the same 4.19v after being charged???

    Contact issue or probably a bad cell. I would say get an exchange or refund, but it's a hassle returning an item to a company located in China.

How about the High Power LiNiCoMn 26650 3.6V 3600maH from batteryspace.com? This is my first post...so thanks in advance for any advice you can lend!
    To answer your question (hope it's okay to do so, as this question is directed at 'anyone'), Elektro Lumens will have 26700A Moli LiMn02 2900mAh, 13C 40A discharge rated batteries available to be purchased in about 1 week or so. These batteries measure 26.4mm x 70.00mm, will fit perfectly in Big Bruiser, and power it easily. Wayne

    Norm,

    Just to confirm, you mean to write 26650 not 26550, correct?

    I am in the same situation looking for protected and high capacity 26650 batteries to power my 2X26650 unit. Althought it came with the 18650 sleeve, I jsut want to test and see what 26650 power would translate into noticeable lumens.

    Anyone bought and tested any.


    Thanks.

    Just want to bump up this thread. I have been using the Keygos 26650 in my Keygos M12, M10, and just recently a Beamtech 4000 a 3x cree light. Not only do the Keygos 26650 run all my lights, that have good runtime also. In addition, I have seen tests on the Keygos 26650 that are rated at 4800Mah, to test out a 4000.

    IMO, the Keygos 26650s are keepers and I just ordered a pair of Trustfire 26650. Hopefully I will get that same results.

    Hi. I bought Keygos M10 (with T6 led), but batteries, which were with it, worked very short time (18650 Ultrafire 3800 mAh). May be some one can advise me which 26650 battery is better to use in this flashlight. Which 26650 is most reliable? And i wonder Panasonic, Sanyo or AW produces such type of batteries or not? Thanks.

    I don't know if this light REQUIRES 3.7V Li-Ion batteries. But if not, there are always A123 Systems Nanophosphate cells. Voltage is only 3.2V nominal, which could be a problem if the light has low voltage protection and doesn't run cells in series. However, current isn't a problem, as they will crank out more amps than, well, anything else out there.

    You guys also might want to check out this thread. I was somewhat frustrated with how the whole purchase of these went, since the only place they are available is direct from Germany, but on the positive side they do ship internationally.

    I did some discharge tests down to 3.0 v under load, and my copies are 98% of rated capacity. They also sell a 4500 mAh unprotected 26650 cell which is a few mm shorter if length is an issue. We'll see how they hold up, but they look great out of the starting block.

    Nailbender also sells some 26650's on his customlites site. They look like the King Kong ICR cells, but it doesn't really say.

    Oveready sells a protected XTAR 26650 cell, I have been tempted to buy one just to see how it does.

    On Vin's sub forum the Xtar 26650 did the best when various cells were tested in the X10vn.

    Battery Space IMR 4000 mAh, MNKE IMR 3500 mAh, EnerPower Protected 4500 mAh, Tensai International Unprotected 4500 mAh



    Battery Space IMR 4000 mAh, MNKE IMR 3500 mAh, EnerPower Protected 4500 mAh, Tensai International Unprotected 4500 mAh



    This graph is not completely apples to apples since the purchase dates on these cells is very different, and also note the discharge rate for the MNKE cell is higher (3.5 A) than the rest of the tests (2.5 A). Nonetheless it is a data point that might be helpful to somebody. The "Blue" are replacing the "Orange" in my inventory.


    • Battery Space IMR 4000 mAh - Purchased January 2010
    • MNKE IMR 3500 mAh - Purchased December 2011
    • EnerPower Protected 4500 mAh - Purchased January 2014
    • Tensai International Unprotected 4500 mAh - Purchased January 2014
