This compact charging board is designed for efficient battery charging in small, space-constrained devices like smart wearables and micro-drones. Its ultra-compact size and lightweight build facilitate easy integration without increasing bulk.

Equipped with a constant current constant voltage (CC/CV) charging mode, the board manages power delivery precisely to optimize charging speed while preventing overheating, thus enhancing battery longevity.

The charging board provides a stable and accurate charge voltage of 4.2V (±1%), ensuring safe and effective recharging of lithium batteries.

It incorporates a trickle charge function for batteries with a low charge threshold of 2.8V, which helps recuperate deeply discharged batteries by supplying a gentle, controlled current.

Thermal regulation ensures the charging board maintains a safe operating temperature throughout the charging process.

The integrated current monitoring output allows for real-time tracking of charging progress, providing insight into power delivery and battery status.

Automatic charging capabilities help maintain battery condition, ensuring readiness for use without manual intervention.

Ideal for users of compact electronic devices such as smart wearables and micro-drones, this battery charging board offers a convenient and reliable solution for maintaining lithium-ion batteries in optimal condition.
