  • Good charger for the price

    posted by hondagourou

    Nice case, slim and efficient.
    Come with a power cord. (look very cheap but i change it with a bettter one)
    The diode show the state of use. (charging and done)
    4.2V end of charge. Don't check the current or charging voltage.
    It may be better but do the job very well.
    Single cell.
    Very good for the price. Match with the cell from the same manifacturer. The led flash to green to show you the charger check the state of charge wile charging.

    There are a few positive aspects! First of all, the whole casing is made of steel Secondly, it is very bright! Great lightning, you don't need additional lenses. Next, it is easy to use, one button and there programs:1. max light, 2. medium power, 3. and quick flashes
    I bought 4 pieces and all the »users« including me are very satisfied with this lamp. I would definetly buy them again. I'm sure that they will last. I also bought additional battery pack, so I can ride my bicycle when battery is recharging. I strongly recomend it. It is also very usefull as headlamp. If you buy this lamp, you will never ever have problems in a dark. You can also use it as stroboscope on rave party.
    This is the bike light I use the most. Lots of light, gets attention even in daylight. Can be used as a bike light or as a headlamp. Cord is a good length. Battery capacity is good.

    I have had 4 Lithium chargers and 9 NiMH battery charges and this is the best. It charges two batteries independently and to different voltages. This allows me to use batteries of different chemistry and it also has different charge rates. I generally slow charge my cells to keep the temperature down and the overall life of the cell high but I love the thought of moving up to the higher charge level if I needed to top of a cell in a hurry. There are times when I discover that my wife put away discharged 18650 cells and we are going on a long night bike ride and we need every cell we have. Its then I move the switch to the higher charge level. The contacts seem to be gold plated for good corrosion resistance. The charge lights blink red then go green when each cell is done.
    If you use Lithium iron phosphate cells this is the charger for you. If you may use those cells one day, get this charger. You may think you will never buy them you could be wrong. The solar flood light sold for outdoor use already use them
    I'm glad I got mine and am working it pretty hard with no issues.
  • Bought for Cree XM-L T6 flashlight

    These are simple high capacity 18650 Li-Ion batteries. What more is there to say? I bought them for my flashlight, and they work an absolute treat. Worth the very minimal investment for the comparative safety of having a quality flashlight for my house and car.
    I don't have the equipment to verify power levels or mAh rating, but I'd gather they do the job just fine. They seem to work as well as my other flashlight's battery does.
    Hard not to recommend them at the price and usefulness. Go for it.
  • Best for the price.

    I am going to have to agree with clunian on this one. These have very high capacity, for the price it is unbeatable. They also have the ability to push out up to 8A for a short period. I have compared them to my AW 2500mah and they are almost identicle. With the exception of these cost 1/4 of the AW.
    A little thicker than most 18650s, which is actually a good thing in most lights as they do not rattle around as much.
    Great battery, if you are new to the site and are looking for something to power that first XML-T6 flashlight for almost an hour on high, this is your battery.
