Product Description:
MH-CD42 DC 5V 2.1A Charge / Discharge (Boost) Battery Protection 4.2V 3.7 Lithium Indicator Module
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
than 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, the same definition applies but in reverse.
