This Lithium Battery Charging Board is engineered for efficient charging of 3.7V lithium batteries.
This well-designed charging module boasts an operational input voltage range of 5-6V, providing reliable and continuous charging.
It's design assures an automatic termination of the charging cycle when the final float voltage is reached and charging current decreases to 0.1A (~100mA).
The charging cycle automatically resumes when the cell voltage falls below 4.05V, corresponding to 80-90% of the battery capacity, guaranteeing a full battery.
When your battery voltage dips below 2.9V, this unit initiates a pre-charging process with a 0.1A (100mA) current to safely bring your battery up to a safe voltage for full 1A (1000mA) charging current.
This Charging Board is built with an integrated protection circuit, providing over-discharge protection and over-current protection, ensuring the safety and longevity of your lithium batteries.
The load is disconnected when the battery voltage goes below approx 2.6v and the load is reconnected when the battery voltage rises to around 3.0v.
The board is simple to use, simply connect it to the charger via USB-C, or power supply via 5V input pins and it's ready to go.
The board is compact, dimensions: 28×17.5mm.
The USB-C socket protrudes approx 1.5mm from the PCB.
