Here we build a Lithium Battery Charger & Booster Module by combining the TP4056A Li-Ion Battery Charger IC and FP6291 Boost Converter IC for a single-cell Lithium battery. A battery module like this will be very useful when powering our electronic projects with lithium batteries. The module can safely charge a lithium battery and boost its output voltage to a regulated 5V which can be used power most of our development boards like Arduino, NodeMCU, etc. The charging current of our module is set to 1A and the output current is also set to 1A at 5V, however, it can also be easily modified to provide up to 2.5A if required and supported by the battery.
