iGPSPORT cycle computers have an LCD screen and two operation buttons, and are powered by a lithium battery. - Brand: iGPSPORT - Model Name: BSC100s - Battery Type: Lithium Battery - Operation Buttons: 2 buttons - Display: LCD screen There are scratches on the mount, but there are absolutely no problems with use. Charging is via Type-C. The battery life seems to be fine, as it lasted about 60km from a flashing (almost dead) state. Feel free to comment if you have any questions! I can also add more photos. No claims and no returns, please. Thank you for looking.
