Why sell lithium not protected?

  • Nietzscheen Saturday, June 5, 2010 6:26 PM Reply
    I ordered by mistake this one because I trough they were protected. And ok, it is my mistake.

    I ordered protected one after finding the mistake.

    Knowing they are not protected, I have a question. I ordered a sku.16501 and own an sku.15456. They are they only flashlight who use this kind of battery I own. All my other run on cr123a, AA, AAA or dynamo.

    Can I use unprotected with my sku.16501 or just with my sku.15456 safely?

    Would it be safe on sku.16501 on low as backup in case of prolonged black-out if it is not on high?

    I brought the sku.16501 for use mostly on full power...

    You can use them safely as long as you know you're not overcharging or over discharging.
    I.e. if you know a fully charged set of batteries should last 2 hours in a flashlight, don't use it for 3-4 before you recharge.

    Unprotected cells are usually a little shorter than the protected versions, and they don't suddenly cut out when the discharge runs too low.

    So reasons to use them would include fitting into lights where the tolerances are too tight for protected cells, or when the task you need the light for makes it more desirable to sacrifice the battery to overdischarge than to have your light suddenly go out (like diving or caving).

    Ok, it is a good idea for diving. You can't change then under water.

    But for other use, I'm more confortable to use protected. I will keep them as a secondary backup or in my sku.15456. It use much less current then my mte m3-2.

    I think I will probably go too low with my MTE M3-2 at first. At less until I know the light a little more and it run time.

    A lot off people seem really scared just because a battery isn't protected!

    I only get non-protected batterys, because i sell flashlights to cyclists and as said above, there are times when you dont want the protection circuit cutting in.
    The people who get the lights from me have NO experience whatsoever with these types of batterys (i give them info on looking after them), and out off 500+ batterys (200+ customers) only one person killed a battery by letting it run down to much.

    Its the same with anything, if you look after it, then it'll be fine.

    I think its because people think they're going to explode, when in reality the most common damage is just that it won't charge after :p

    Then I can use them. I was not sure about unprotected as I does not fully trust Chinese charger. As I hear that lithium could catch in fire. I was a concerned about safety. I can't monitor a recharge cycle for 4 hours...

    I was just keeping it on the safe side because for the use I have in mind (walking) it is not fully catastrophic got the light going down immediately. I always carry a secondary battery and keep a Fenix E01 GX as backup on my keyring.

    Unprotected cells are perfect for replacing cells of portable computer batteries, which have their protection circuit not on cell level, but on battery block level.
    Why shouldn't DX sell those cells for these purposes?

    unprotected cells are also good for making laptop battery packs since the battery already has a protection circuit its not needed. actually longer protected cells will not fit the battery casing.
