Description
Providing mobile power for your DIY projects has never been easier with the MH-CD42 Power DIY board. This tiny board offers simultaneous charge and discharge, lithium battery protection, and a 4 level LED indicator. Connect any kind of 3.7V Lithium battery to have a 5V output with current up to 2.1A.
When charging, the four level battery indicator starts with one flashing LED, meaning the battery is less then 25% full. After some time, 2 LED will lit up and the first one would stop flashing. That means your battery is 25% to 49% full. Your battery is fully charged when all 4 LEDs are lit and not flashing. In discharge mode, same definition applies but in reverse.
