Description
3.7V Single Cell Li-Po Charger/Discharger Maintainer Board
This project is a continuation for my Li-Ion_Charging_Module_v2
This PCBs funtion is to charge and discharge your Li-Po battery so that you can leave your battery to store charge or fully charged state. You can use Micro USB connector to power this device or power it from Molex cable. Molex cable voltage should be 12V to 14V, which is a standard voltage coming out of a 12V lead acid battery. You can also feed through USB voltage out from the board so that you can power another project through this because there is a 1A fuse in line. This project requires to install a Li-Ion Charging Module v2 that I have designed.
