## Description

The JacobsParts Ultra-Small Lithium Battery Charging Board is engineered for efficient charging of 3.7V lithium batteries. Compact and weighing practically nothing, it incorporates a powerful 1A high current linear charging system, delivering fast and reliable charging. This product includes a Type-C interface for the power source, achieving compatibility with most PD chargers and ensuring broad connectivity. This well-designed charging module boasts an operational input voltage range of 5-6V and offers a stable output voltage of 4.2V, providing reliable and steady charging. Its intuitive design assures an automatic termination of the charging cycle when the final float voltage is reached and the charging current decreases to 100mA. The charging cycle automatically resumes when the battery voltage falls below 4.05V, corresponding to 80-90% of the battery capacity, guaranteeing a full battery. When your battery voltage dips lower than 2.9V, this unit initiates a pre-charging process with a 100mA current to safely and steadily rejuvenate your battery. The JacobsParts Charging Board is built with an integrated protection circuit, providing over-discharge protection with a value of 2.4V and over-current protection of 4A, ensuring the safety and longevity of your lithium battery. The board is simple to use, simply connect it to the power supply and it's ready to go. Despite its numerous functionalities, the board is surprisingly compact with dimensions of 14×18×5mm. The Type C port projects approximately 1.5mm, adding hardly any bulk to the unit.
