ultrafire battery pack Customers Reviews

  • Great capacity, a bit big though

    posted by kfallscody

    The protection circuit works well. Gives peace of mind knowing you can't really over-discharge them.
    Batteries work great, have a nice capacity. Have already ordered more.. :)
  • Great batteries - handle with care

    These are great protected cells I think the stated capacity is pretty accurateHold voltage well under loadSize is pretty close to a regular AANipple tip so no need for magnetsProtection circuit works
    They are protected but water, fire and puncturing can still burn your house downRespect the chemistry used and handle with care and they should not cause you any griefKeep away from kids - do not use in kids toys and charge them somewhere fire proof
    Great - super cheap - safety built in but read up on LI Ion before use
  • Excellent Purchase!

    1) It is a 2400mAh capacity battery.2) 2 batteries (@ ~$5 for one)3) PCB protection against overvoltage, overdischarge, and overcharge4) Build quality on par with major brand names
    I'll be using it to build a battery pack for a old cordless drill since I can't buy any Li-Ion battery packs for the drill.

    The larger size isn't much of a hamper, although it is much larger than I had expected (roughly double the volume of that of a standard AA). The high capacity is great and it has a PCB.

    I'm sure it'll be a great buy for those high-drain CREE and Luxeon LED lights (if you can get one to fit).
    Cheaper than any retail or online store in the U.S. for the same brand and quality battery. PCB equipped for about $5 a battery.

    Buy it if you need these 18650 batteries or want to build a battery pack out of them.

  • Great price!

    They fit in my 18650 using devices perfectly (A Fenix TK11 and a SpiderFire SSC P7) and seem to work fine.
    Price is excellent, much lower than I found elsewhere.
    They're batteries, at this price you may as well have a few in reserve and keep them charged and ready. I wanted to have some spares in for camping to save me lugging chargers with me.
