    Quad cree led !

    I would think driving all four in series would force the dies to have a more consistent brightness... driving them in parallel, I can see why you might get those results.

    GTL 18650 Battery Test [ Updated ]

    Too bad you can't somehow link this review to the seller's Feedback on ebay... thanks for testing those cells, very small sample size but obviously 2800 is a HUGE LIE !!!

    Bosch 36V Lithium Ion - What cells are in there?

    :candle: so nobody has taken one apart yet ? Am I posting in the wrong section ?

    Bosch 36V Lithium Ion - What cells are in there?

    I'd like to know because I saw a Pack for sale on fleabay for ~ 99.00 :whistle: I'm wondering if the cells are comparable to the Dewalt 36v (A123 - 10 cells) and the Milwaukee V28 (emoli - 7 cells)

    fenix on a bike?

    My P1D-CE fits just fine on the old Cygolite mount I previously used with dual 10 watt halogens. http://www.shop.cygolite.com/category.sc?categoryId=34 I tightly wrap the Fenix with some velcro strips in a cross pattern. I can adjust the light's direction just enough and the light doesn't...

    Goog Li-ion charger for unprotected cells?

    Lithium Ion and CHEAP and SAFE don't really go together.

    How do I put a PCB to a 18650?

    Probably easier to buy a Protected 18650 - the work is already done for you!

    which battery do you prefer

    Where's the Li-Ion 18650 choice? (that's mine)

    Converting a Voltage regulator to Current regulator

    http://theledguy.chainreactionweb.com/index.php/ has some current regulated boards for sale. You could take a look there. Put the circuit together and see what happens..... what the heck! Or put it together "virtually" with a freeware program like Linear Tech's LTSpice program

    500,000 + Watts, WOW!

    Cool! A HIGH CURRENT Lithium Ion! The 26650's are rated at 2.3 Amp Hours per cell (similar to a regular Li-Ion). So at 40 amps, you won't get much runtime....

    Battery Power Indicator (green/yellow/red) circuit?

    Temperature, Load Current and Battery Chemistry will effect your readings too.... How about those coulomb counter IC's?

    Hacker(s) have thrashed Wiki Battery Chart

    I was going to send somebody (battery help thread) a link to http://www.wiki.tjtech.org/index.php/The_Rechargeable_Battery_Compatibility_Chart but I see that it has been taken over by some Hackers.... :xyxgun: who can fix this?? :help:

    Stupid questions...

    When driving any Light Emitting Diode, the VOLTAGE across the LED (and the internal resistance of the power source) will determine the current running through the LED. LED's do NOT have a linear response to voltage either, it's a curved line (on a graph of Voltage/Current). Take a look at...

    Nobody Prefers Single-Level Lights?

    A single level light is like a one-speed bicycle, motorcycle or car. It's simple and therefore reliable. On the other hand, it's somewhat limiting. Even though my mtn bike has 27 speeds, I STILL don't always have the gearing I want, or the chain flies off and I get stuck. All things are a...
