  • 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.
  • More juice for your lights

    A great battery to have if you own as many flashlights as me. They may not give as much voltage as compared to rcr123's, but they sure do give a hell of a longer run time. If you own any other flashlights that use x3 AA batteries in that D battery shaped adapter, these puppies could replace them (with a few modifications) making them brighter and hold a charge much much longer!
    Don't forget the charger.
    Buy these if you need em, but remember there are others with higher mAh.
  • Good but capacity overrated

    posted by Schneizel

    Protection circuitry prevents over-discharge and over-charge.Length is pretty close to 65mm. Never actually measured but it fits in my X2000 torch. Some complain that protected 18650s don't fit in this torch.
    You could buy this if you need protected cells but personally i would recommend the trustfire 2400mAh in black/red. They're just ~$2 more and they give a true capacity of 2400mAh.
  • Very powerful batteries with low price

    Very powerful batteries. their capacity is equal to announced capacity. Or very close to it.I use them with 637 Cree XM-L T6 1000lm flashlight. Even after first charging it was able to work without pauses more then 7 hours!
    Batteries came with nice plastic case. It is very comfortable for batteries storage.
    I can recommend these batteries to all who wants to buy it.It is great batteries with very cheap price!
  • Great Battery for low-price

    It has integrated PCB Protection, are good for lighting or other device needing 3.7V power, like old notebooks!
    Can be charged for long time due to PCB.
    My flashlight shines brigth than ever!
    Ah! And it's Pink and not Red like they said. I preffer blue or black, but works ok
    You need to buy it for your works!
    Thank you, again!
