This is a standalone Lithium battery charger which lets you charge up your batteries from a micro USB cable.  The battery can connect to a JST SH connector  (the battery connector on the batteries that we sell at TinyCircuits). You can also use this without the JST connector with two large through holes to connect to a battery pack.  

Simply plug the USB side with a cable into a USB port, and plug a lithium polymer or lithium ion rechargeable (3.7V / 4.2V) battery into the other side and it will start charging.  A status LED on the board will indicate when charging, and will turn off when fully charged.  

Note: The battery and the microUSB cable are not included.   

    • 2-Pin JST SH Connector for battery connection
    • Includes two solder tabs to connect directly to battery terminals if desired
    • 100 mA charge current (can be set to 500mA with a resistor change)
    • Status LED indicates when charging
    • Robust Gold Finish – makes soldering easy and is non-corrosive

      Dimensions

      • PCB Dimensions: 14mm x 9mm (0.511 inches x 0.354 inches)
      • Max Height: 3.7mm (0.146 inches)
      • Thin 0.61mm (0.024 inches) PCB
      • Weight: 0.540 grams (0.019 ounces) 
      • The charge current can be changed to 500mA by moving R5 (next to the 0.1mA label on the silkscreen) to the R4 (next to the 0.5mA label on the silkscreen) position.

      Perfect solution for Hotwheels Car

      My sons Hot Wheels Tesla Truck charging circuit stopped working so I used this as a replacement. Works great.

      Outstanding Service & Quality!

      I am absolutely a customer for life! I received my order several days after placing it, product and packaging is of the highest quality, and everything works perfectly! Amazing!

      I wish this whole concept (Tiny, Ard and Pi) were around when I was 10 years old!

      Tiny Battery Charger - Normal sized Charge

      It does exactly what it says and what you'd expect. It changes a lipo battery with a 1mm pitch JST SH connector. I didn't try the 0.5A rate - just the default .1A - but nice to know if I wanted to fast charge...I could. Thing is...the battery I am charging is so small - even at .1A rate it charges in a short time.
      This and the small lipo with matching JST SH connector are perfect for my Minifigure Sized board: https://minifigboards.com
      Thanks for making a great product!
