  • Good batterys for a good price

    The batteries do what they should do. The build quality seems to be ok, too. They have protection circuits, but still fit in my flashlight (FandyFire 5xCree XM-L T6 4000 lm) The cases in which the batteries are delivered are very helpful, if you take the batteries on a camping trip or something like that.
    I can not verify the battery capacity (2600mAh), but it seems to be ok.
    Good batterys for a good price. If you buy these, you do nothing wrong. :-)The delivery from DX was good. It is normal, that it takes about 2-6 weeks delivery time to gemany.
  • Powers Arduino UNO

    posted by LynnCochran

    Provides 9 volt power to my Arduino UNO, when it's not powering another high-current project of mine. The 5.5/2.1mm "barrel" power plug fits Arduinos, with positive in the center of the connector (if the batteries are installed correctly ;) I have not had problems inserting the batteries into this enclosure, but I add the center battery on each side last (and remove it first).
    Price could be a bit lower.
    If you need a 9V battery source to power an Arduino in a standalone project for a long time, this pack will do the work.
  • Good, it's what I needed

    it's a good soldered PCB and offers a well-working open platform for USB charge or additional sources. Clearly labeled and very easy to use and install
    I looked for this solution and this price for a long time, now I found it
    Time of ownership was a bit too long, but at the end I can be satisfied by my shop
  • Excellent

    Great card. Works out of the box for mp3 and radio. Sound quality is good enough for lot of projects.
    I thought I could hack it for integration in another project. The radio chip is commanded by I2C so it was easy, but the “main” chip is not known anywhere on the internet.Buttons are made to be integrated inside a case, quite difficult to press but I cut the PCB to connect others.
    At this price experimentations are easy.If you want to switch radio/mp3 just press and hold center button
  • It works well and description appears accurate.

    Useful size and form factor. Provided suction cups help in attaching the panel to windows inside the car, or on the inside of the window of the house (as how I had used it). I leave mine permanently attached to a used 12V car battery (without a solar charge controller) and it always keep it well-charged without overcharging it.
    I suspect this panel does not have a built-in blocking diode that prevents the panel from drawing power from the battery when the sun goes down, but I can't verify that as it doesn't bother me too much.
    Useful and decent quality panel, albeit a little bit expensive.
