  • Excellent Purchase!

    posted by intelboy15

    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.

    posted by loonwulf

    Great battery life, consistant output, good charge holding, and has functioned properly for over 3 years.
    great product at a great price, i like these the best of any of the batteries ive used so far. Ill be ordering more of them soon
    I can highly recommend these batteries, ive used my set for 3 years and change, and have nothing bad to say about them.
  • Protected cells at an attractive price.

    posted by SirJMD

    The cells comes nicely wrapped, so they wont get damaged during shipping.- Excellent price for two batteries.- Protected cells!- Comes pre-charged (most likely charged, due to the chemical process, when they were manafactured)
    Rather see some cells with an accurate capacity label - at least DX says that its not to be trusted.
    Decent cells for the price!

    Works as it should. No hiccups up to now.
    Bought this item for sku.6951. Batteries fits nicely.
  • Great Li-ION pack

    posted by Gekkie

    This is a great Li-ION pack. I am using this in a homemade circuit and only have to recharge it after 1 week of running. The battery is a little big due to the proctection circuit. I was suprised that it came in a little box which I then used to house my circuit.
    Good pack at a really good price, be carefull when shipping as China mail is giving people a hard time for sending li-ion packs. So check the forums!
