    MagCharger Circuit: Can You ID the Components?

    Yep, what Wilkey said. And as the cells charge, the voltage will slowly rise until the cells top off. The beauty of this setup is that you can change battery configurations (such as going from 5-cell NiCad to 9-cell NiMH and vice versa) without having to change the charger.

    CR123s vs. rechargeables

    Don't forget that with many 123 lights, rechargeable 123's work well. The Arc4 is particularly good, but anything using a BadBoy sandwich (such as the FireFly) works well. I've been running such a setup for quite a while and it works very well - and I haven't had to use a single CR123 in months.

    Rechargeable CR123's

    Re: Rechargeable CR123\'s The protection circuits are designed to solve the very problem you speak of: dangers from overcharging/discharging. Protected cells are much safer, but should still be regarded as potentially dangerous. Caution is always advisable. Nevertheless, when used properly...

    High capacity, high current AA - Impossible?

    The discharge curves on those GP batteries look very nice, but I wish they were button tops. I found these (http://www.gpina.com/pdf/180AAHC.PDF) on that site. They appear to perform just as well, are 1800mAh, and have button tops. Pretty darn nice. Edit: Even better -...

    High capacity, high current AA - Impossible?

    I've been trying to find the highest capacity AA battery that will run a WA 1185 which draws 3.15A nominally. It'd be nice to have a little buffer built in, so a battery that will provide at least 4A continuous current would be ideal. On Supreme Power's website, I found this datasheet for...

    CR2 vs. CR123

    I am highly in favor of the CR2 cell. I wish more lights took advantage of their small size. I'm particularly looking forward to Larry's CR2II, if it ever becomes publicly available. The disadvantages, as mentioned, are shorter runtime and lower load-bearing ability (and therefore...

    Li-Ion / Li-Polimer 3.6 / 3.7 V Battries

    An 18650 cell has an 18mm diameter and 65mm length. It's about the size of 2 123s, except a tad thicker and a tad shorter. An AA sized Li-Ion would be 14500 (14mm diameter x 50mm length). I believe there is a possible group-buy for these in that forum.

    Energizer Rechargable AA NiMH 1850mAH Batts

    Wal-Mart sells some Energizer 2300mAh AAs. I believe an 8-pack is only around $18 US.

    Where to get rechargeable 123's?

    Re: Where to get rechargeable 123\'s? There are mixed reports, so proceed at your own risk. I'll be using rechargeable 123s with my Fire~Fly, and if I ruin my converter/LED then what a great time to upgrade!

    Where to get rechargeable 123's?

    Re: Where to get rechargeable 123\'s? To pre-order, just add them to your cart and pay like you would with any other item. The only difference is that it will take a little longer to get to you. But at least you will ensure yourself a set. They are indeed Li-Ion. The nominal voltage of the...

    Amperage Question for Various single 123 lights

    I believe Peter said the maximum a Arc4+ should draw is 1.25A. A good one would be lower, and anything above that would be a second. So there are probably lots of seconds out there that draw over 1.25A.

    MagCharger Circuit: Can You ID the Components?

    No prob, Nitro. Thanks for the idea. Actually, the current now seems to stabilize at 137.0mA. Talk about exact calculations. Nice work. I now feel like I have a complete MagCharger solution. I'm running a WA01160, Wilkey UMP, UCL-LDF lens, and soon Otokoyama's orange-peel PMR. I've got a...

    MagCharger Circuit: Can You ID the Components?

    Yes you can. Though there's not much room on the board, so I just folded a piece of copper wire and jammed it under the resistor so that it was touching both the leads. The slight tension of the folded wire kept it firmly in place, so I don't think there's any danger of it falling out...

    Rechargeable 123s, the next step.

    The charging voltage should be whatever it takes to get the full capacity of the cell. In this case, the chargers should charge to 4.2V because of the battery chemistry. There is no sense in paying for a battery that only gets charged to a fraction of its capacity. If the manufacturer could...

    Use Maha 401 to charge other batteries?

    I don't see why it would be a problem, though I have no idea what I'm talking about. I have this charger, and it correctly charges my old 1500 mAh NiMH, which is pretty close to the cells in question, as well as 1000 mAh NiCD. The charger shouldn't care if you use leads.

    Li-Ion Rechargeable 123's - Review Thread

    Re: Li-Ion Rechargeable 123\'s - Got mine today Maybe the charger manufacturer could put a switch on the charger: "Compatability Mode (3.6V)" or "Performance Mode (4.2V)"
