DIY Lithium Battery Charger 15 Steps Circuit Diagram
DIY Lithium Battery Charger 15 Steps Circuit Diagram You cannot "trickle charge" a lithium battery. If you keep pushing current in, the voltage just keeps on rising until the battery catches fire. If you keep a constant voltage, the current

The following Li-Ion battery charger circuit very efficiently follows the above conditions such that the connected battery is never allowed to exceed its over charge limit. When the IC 555 is used as a comparator, its pin#2 and pin#6 become effective sensing inputs for detecting the lower and the upper voltage threshold limits depending upon Building the 3.7V Li-Ion battery charger. Construction of this charger circuit is undoubtedly a difficult exercise for many beginners and hobbysists because the task calls for perfect skill in SMD soldering/prototyping. Fortunately, readymade Li-Ion Battery Charger Modules are now available at many online stores.

All these things are assembled on TP4056 Li-ion battery charger breakout board whose link is mentioned in step No-2. We need to do only two things, give a voltage in the range of 4.0 to 8.0 V at input terminals and connect a battery at B+ and B- terminals of TP4056. Place 7805 voltage regulator circuit; use glue gun to make a firm joint

Li-Ion Battery Charging. Li-Ion batteries are commonly used in smartphones, laptops, and other portable electronics. These batteries are charged using a constant voltage source, typically around 4.2 volts per cell. It is important to avoid overcharging a Li-Ion battery, as this can cause damage and reduce its lifespan.
